7.Description:
(en)This application is a continuation-in-part of application for United States Letters Patent, Ser. No. 228,512 filed on Aug. 5, 1988 now U.S. Pat. No. 4,946,782.
BACKGROUND OF THE INVENTION
This invention is concerned with a microbial process for the production of compositions of matter containing unsaturated lactones.
Considerable time and effort have been expended by microbiologists in the search for better processes for the production of unsaturated lactones; and more generally lactones per se. U.S. Pat. No. 3,076,750 discloses a method of preparing certain optically active lactones and the corresponding hydroxycarboxylic acids by microbial reduction of ketocarboxylic acids. The metabolism of ricinoleic acid by some Candida strains was investigated by Okui, et al (J.Biochemistry, 54,536-540, 1963) who showed that gamma hydroxydecanoic acid was an intermediate in the oxidative degradation of ricinoleic acid. However, only trace amounts of gamma hydroxydecanoic acid were recovered from the fermentation medium due to the metabolysis of gamma hydroxydecanoic acid upon completion of the fermentation, and the toxicity of ricinoleic acid to the microorganism, which limits the amount of substrate that can be used.
U.S. Pat. No. 4,560,656 provided a method of producing optically active gamma hydroxydecanoic acid comprising culturing or incubating a microorganism capable of hydrolyzing castor oil, and effecting beta-oxidation of the resulting hydrolysate in the presence of castor oil, to produce gamma hydroxydecanoic acid.
U.S. Pat. No. 4,560,656 also provided a method of producing optically active gamma hydroxydecanoic acid comprising enzymatically hydrolyzing castor oil using lipase to form an enzymatic hydrolysate and culturing or incubating a microorganizm capable of effecting beta-oxidation of the enzymatic hydrolysate in the presence of said hydrolysate to produce gamma hydroxydecanoic acid.
U.S. Pat. No. 4,560,656 also provided a method of producing optically active gamma hydroxydecanoic acid comprising culturing or incubating a microorganism capable of hydrolyzing castor oil and a microogranism capable of effecting beta-oxidation of castor oil hydrolysate in the presence of castor oil to produce gamma hydroxydecanoic acid.
European Published Patent Application 258993 published on Apr. 9, 1988 discloses a process for the production of optically active gamma hydroxydecanoic acid suitable for conversion to optically active gamma decalactone. The process covers steps of:
(a) culturing sporobolomyces odorous; and/or rhodotorula glutinis on a medium containing a ricinoleic acid sources at 15°-35° C. at a pH of 3-9 and optionally; and
(b) lactonizing the resulting gamma hydroxydecanoic acid to gamma decalactone.
Nothing in the prior art however discloses the ability by means of fermentation to create a novel mixture of unsaturated lactones together with, optionally, gamma decalactone found to be useful in augmenting or enhancing the organoleptic properties of consumable materials.
In the flavor and fragrance art, a need has arisen for the development and efficient production of naturally occurring lactones which have heretofor been found to be useful and necessary in the creation of flavor formulations used in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos and smoking tobaccos and also useful in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and the like).
Although U.S. Pat. No. 4,560,656 has partially fulfilled the need for provision of saturated gamma decalactone defined according to the structure: ##STR8## nothing in the prior art sets forth the creation of unsaturated lactones defined generically according to the structure: ##STR9## and defined more specifically according to the structures; ##STR10##

Referring to FIGS. 20 and 21, there is provided a process for forming scented polymer elements (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250° C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 20 and 21, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polyproyplene, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and the perfuming substance which is at least one of the lactones of our invention or mixtures of lactones and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostate or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds. The heater 218 is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220°-270° C. in the case of low density polyethylene. The bottom portion of the container 212 is heated by means of heating coils 212 A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220°-270° C.
Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the lactones of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.
After the perfume material is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coil 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the lactones of our invention or mixture of perfume substance and one or more of the lactones of our invention, will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240°-250° C., for example, (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer intimately admixed with the perfume substance which is all or which contains one or more of the lactones of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for the formation of other functional products, e.g., garbage bags and the like.
SUMMARY OF THE INVENTION
Our invention relates to a method using fermentation techniques to produce and recover certain naturally occurring lactones found to be useful for their organoleptic properties in augmenting or enhancing the aroma or taste of consumable materials such as foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, smoking tobaccos, perfume compositions, colognes and perfumed articles, e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, cosmetic powders, hair preparations and the like which lactones are defined according to the structures: ##STR53## and taken alone or taken further together with the lactone having the structure: ##STR54## wherein R represents C 6 alkyl or alkenyl, and X represents alkylene or alkenylene with the proviso that R is C 6 alkyl when X is alkenylene and R is C 6 alkenyl when X is alkenylene. The lactone compositions are produced by means of fermentation of castor oil or ricinoleic acid or a castor oil hydrolysate to form a mixture of carboxylic acids having the structure: ##STR55## together with gamma hydroxydecanoic acid according to the reaction: ##STR56## with the reaction of the castor oil going to the ricinoleic acid being shown, thusly: ##STR57## More specifically, the fermentation reaction of the ricinoleic acid going to the various carboxylic acids is shown according to the reaction: ##STR58## The fermentation reaction is effected as a result of the presence in the reaction mass of certain organisms, to wit, one of:
Candida petrophilum, ATCC 20226;
Candida oleophila, ATCC 20177;
Candida sp., ATCC 20504; or
Candida sake, ATCC 28137.
The resulting reaction mass is then subjected to a pH reduction to a pH in the range of 0-5 and heated at a temperature in the range of about 90° up to about 120° C. whereupon lactonization of the gamma hydroxydecanoic acid takes place, thusly: ##STR59## The other acids in the reaction mass do not lactonize.
The third step of the process of our invention involves distillation of the reaction mass at a temperature in the range of 120°-220° C. and at a pH of between about 1 and about 7 whereby the unsaturated acids lactonize according to the reaction: ##STR60## wherein the sum of the carbon atoms in the X moiety and in the R moiety is equal to the number of carbon atoms in the Y moiety minus 1 and wherein Y represents an oxo-saturated, oxo-unsaturated or di-unsaturated C 9 , C 11 or C 13 moiety.
The resulting products, in the form of mixtures of lactones or as separate lactones or groups of lactones are useful in augmenting or enhancing the aroma or taste of consumable materials as set forth, supra.
The first step of the process of our invention involving the reactions: ##STR61## takes place at a pH in the range of 5.5 up to 7 and a temperature in the range of from about 20° up to about 35° C.
Prior to the reaction taking place an inoculum is produced whereby the microorganism, e.g., Candida petrophilum, ATCC 20226 is grown in olive oil for a period of about 10 up to about 30 hours. The resulting inoculum is then admixed with castor oil or a castor oil hydrolysate substrate.
The form in which the microorganisms are used is not critical. They can be used as the culture (suspension), i.e., including the cells and the corresponding nutrient solution, or in the form of cells suspended in a buffer solution. The cells or an enzyme extract thereof may be immobilized on a suitable solid support which may then be used to effect the transformations
The culture suspension is prepared by inoculation of a suitable medium with the microorganism. A suitable medium is one which contains carbon sources, nitrogen sources, inorganic salts and growth factors. Among the suitable carbon sources are for example, glucose, galactose, L-sorbose, maltose, sucrose, cellobiose, trehalose, L-arabinoise, L-rhamnose, ethanol, glycerol, L-erythrithol, D-mannitol, lactose, melibiose, raffinose, meleitose, starch, D-xylose, D-sorbitol, alpha-methyl-D-glucoside, lactic acid, citric acid and succinic acid. Among the suitable nitrogen sources are, for example, nitrogen-containing organic substances such as peptone, meat extract, yeast extract, corn steep liquor, and casein, urea, amino acids, or nitrogen containing inorganic compounds such as nitrates, nitrites, and inorganic ammonium salts. Among the suitable inorganic salts are, for example, phosphates, magnesium, potassium, calcium, sodium. The above mentioned nutrients in the culture medium may be supplemented with, for example, one or more vitamins of the B Group and/or one or more trace minerals such as Fe, Mo, Cu, Mn, B as desired. However, the process can be performed in a vitamin-free medium; for example, when a small amount of yeast extract is added to the medium there is no need for vitamins or trace minerals.
The cultivation of the microorganism can be carried out as a stationary culture or as a submerged culture (e.g., shaking culture, fermentors) preferably under aerobic conditions. One suitably may work in the pH range of from about 3.5 to about 8.0, and preferably in the range of from about 4.0 to about 7.5. The pH may be regulated by the addition of inorganic or organic bases, such as sodium hydroxide, potassium hydroxide, calcium hydroxide, calcium carbonate, by ion-exchange resins, or by the addition of a buffer such as phosphate or phthalate. The incubation temperature is suitably maintained at between about 15° C. and about 33° C., with a range from about 20° C. to about 30° C. being preferred.
The process in accordance with the invention is conveniently carried out by adding castor oil or castor oil hydrolysate, as the substrate, to the culture medium at the onset of cultivation, as the sole carbon source. Alternatively, the substrate may be added in combination with another carbon source, such as dextrose, either during cultivation, or when cultivation is complete. The amount level, or concentration of the substrate in the medium may vary. For example, in the case of hydrolyzed castor oil, levels of from about 0.3% to about 5% may make up the medium initially or be added during the course of the fermentation, whereas substantially any level of castor oil may be used. The reaction time may vary depending on the composition of the culture medium and the substrate concentration. In general, shaking flask cultures require from between about 2h. and about 240h. depending upon the microorganism and the composition of the culture medium. However, when a fermentor is used the fermentation time may be reduced to about 100h. or less
The fermentation may be carried out using the cells of the microorganism isolated from the culture solution, or with an enzyme extract isolated from the cells in a manner known per se In this case, the fermentation can be conveniently carried out in aqueous solution, for example, in a buffer solution, in a physiological salt solution, in a fresh nutrient solution, or in water. The isolated cells or enzyme extract may be immobilized on a solid support and the desired transformation effected in the absence of the live microorganism. The transformation of the substrate may be effected by mutants of the microorganism. Such mutants can be obtained readily by methods well known in the art, for example, by exposing the cells to UV or X-rays, or customary mutagenic substances such as, for example, acridine orange.
The substrate is generally added directly to the medium. A surface-active agent or dispersion agent, such as TWEEN® 80 polyoxyethylenesorbitan monostearate), can also be added to an aqueous suspension of the substrate. Conventional antifoam agents, such as silicone oils (e.g., UCON), polyalkyleneglycol derivatives, maize oil, or soya oil can be used to control foaming.
The transformation of the substrate can be monitored using standard analytical techniques such as GLC, TLC, HPLC, IR and NMR. If a rapid disappearance of the substrate is observed, more substrate can then be added in order to maximize the transformation capacity of the microorganisms. The incubation is generally terminated when all the substrate has disappeared from the culture medium.
After the fermentation process is complete, the lactonization steps may take place. The first lactonization, involving the reaction of gamma hydroxydecanoic acid, to wit: ##STR62## takes place at a pH in the range of 0-5 at a temperature of 90°-120° C. The pH is adjusted using acids such as 85% aqueous phosphoric acid. The reaction time may vary from about 0.25 hours up to about 2 hours. During this first lactonization step the unsaturated carboxylic acids defined according to the structure: ##STR63## e.g., the carboxylic acids having the structures: ##STR64## do not lactonize.
However, when the resulting mixture containing the gamma decalactone having the structure: ##STR65## is distilled at 120°-220° C. while the pH of the reaction mixture is in the range of 1-7 lactones having the structures: ##STR66## are produced according to the reactions: ##STR67##
The lactone derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters other than the lactone derivatives of our invention, ethers, synthetic essential oils, and natural essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the fruity area (e.g., peach and apricot aromas). Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation and (d) topnotes which are usually low-boiling, fresh-smelling materials.
In perfume compositions, it is the individual compositions which contribute to their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the lactone derivative(s) of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of lactone derivative(s) of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.005% of lactone derivative(s) or even less (e.g., 0.002%) can be used to impart sweet, fruity (peach and apricot) aromas to soaps, cosmetics, detergents including anionic, cationic, nonionic and zwitterionic solid or liquid detergents, perfumed polymers and other products. The amount employed can range up to 70% of the fragrance components and will depend upon the consideration of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
The lactone derivative(s) of our invention are useful (taken alone or taken together with other ingredients in perfume compositions) in detergents, soaps, space odorants and deodorants, perfumes, colognes, toilet waters, bath preparations, hair preparations such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like.
As little as 0.25% of the lactone derivative(s) will suffice to impart an intense, sweet, fruity (peach and apricot) aroma to floral perfume formulations. Generally no more than 5% of the lactone derivative(s) based on the ultimate end product is required to be used in the perfume compositions.
Furthermore, as little as 0.25% of the lactone derivative(s) will suffice to impart such aromas to perfumed articles per se, whether in the presence of other perfume materials or whether used by themselves. Thus, the range of use of the lactone derivative(s) of our invention in perfumed articles, e.g., perfumed polymers and solid or liquid anionic, cationic, nonionic or zwitterionic solid or liquid detergents, may vary from 0.25% up to about 5% by weight based on the total weight of the perfumed article.
In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the lactone derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethanol, a non-toxic glycol, e.g., propylene glycol, or the like. The carrier can also be an absorbent solid such as a gum (e.g., gum arabic or xanthan gum or guar gum) or components for encapsulating the composition by means of coacervation (such as by gelatin) or by means of formation of a polymer around a liquid center (as by using a urea formaldehyde prepolymer to form a polymeric capsule around a perfume composition center).
It will be appreciated from the present disclosure that the lactone derivatives according to the present invention can be used to alter, vary, fortify, modify, enhance or otherwise improve the flavor of a wide variety of materials which are ingested, consumed or otherwise organoleptically sensed.
The terms "alter" and "modify" in their various forms will be understood herein to mean the supplying or imparting of a flavor character or note to an otherwise bland, relatively tasteless substance, or augmenting an existing flavor characteristic where the natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its organoleptic character.
The term "enhance" is intended herein to mean the intensification (by use of the lactone derivative of our invention) of a flavor or aroma note or nuance in a tobacco flavor or foodstuff or perfume composition or perfumed article without changing the quality of said note or nuance.
A "flavoring composition" is taken to mean one which contributes a part of the overall flavor impression by supplementing or fortifying a natural or artifical flavor in a material or one which supplies substantially all the flavor and/or aroma character to a consumable article.
The term "foodstuff" as used herein includes both solid and liquid ingestible materials for man or animals which materials usually do, but need not, have nutritional value. Thus, foodstuffs include meats, gravies, soups, convenience foods, malt, alcoholic and other beverages, milk and dairy products, seafoods, including fish, crustaceans, mollusks and the like, candies, vegetables, cereals, soft drinks, snacks, dog and cat foods, other veterinary products, and the like. The lactone derivative(s) of our invention are also useful tobacco flavorants and flavor enhancers.
The term "tobacco" will be understood herein to mean natural products such as, for example, burley, Turkish tobacco, Maryland tobacco, flue-cured tobacco and the like including tobacco-like or tobacco-based products such as reconstituted or homogenized leaf and the like as well as tobacco substitutes intended to replace natural tobacco such as lettuce and cabbage leaves and the like. The tobaccos and tobacco products in which the lactone derivative(s) of our invention are useful include those designed or used for smoking such as in cigarettes, cigar and pipe tobacco, as well as products such as snuff, chewing tobacco and the like.
When the lactone derivative(s) of this invention are used in a flavoring composition, they can be combined with conventional flavoring materials or adjuvants. Such co-ingredients or flavoring adjuvants are well known in the art for such and have been extensively described in the literature. Requirements of such adjuvant materials are: (1) that they be non-reactive with the lactone derivative(s) of our invention; (2) that they be organoleptically compatible with the lactone derivative(s) of our invention whereby the flavor of the ultimate consumable material to which the lactone derivative(s) are added is not detrimentally affected by the use of the adjuvant; (3) that they be ingestibly acceptable and thus non-toxic or otherwise non-deleterious. Apart from these requirements, conventional materials can be used and broadly include other flavor materials, vehicles, stabilizers, thickeners, surface active agents, conditioners, and flavor intensifiers.
Such conventional flavoring materials include saturated fatty acids, unsaturated fatty acids and amino acids; alcohols including primary and secondary alcohols, esters, carbonyl compounds including ketones and aldehydes; lactones; other cyclic organic materials including benzene derivatives, allicyclic compounds, heterocyclics such as furans, pyridines, pyrazines and the like; sulfur-containing compounds including thiols, sulfides, disulfides and the like; proteins; lipids, carbohydrates; so-called flavor potentiators such as monosodium glutamate, magnesium glutamate, calcium glutamate, guanylates and inosinates; natural flavoring materials such as cocoa, vanilla and caramel; essential oils and extracts such as anise oil, clove oil and the like and artificial flavoring materials such as vanillin and the like.
Specific preferred flavor adjuvants are as follows:
anise oil;
ethyl-2-methyl butyrate;
vanillin;
cis-3-heptenol;
cis-3-hexenol;
trans-2-heptenol;
cis-3-heptenal;
butyl valerate;

gamma hexenyl lactone;
2,4-decadienal;
2,4-haptadienal; and
butylidene phthalide.
According to another aspect of our invention, an organoleptically improved smoking tobacco product and additives therefor as well as methods of making the same which overcome specific problems heretofore encountered in which specific Turkish, oriental-like aromas prior to smoking and improved Turkish, oriental aromas on smoking in the main stream and the side stream are created or enhanced or modified or augmented and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend. In particular, low grade Virginia-type tobaccos may be upgraded using the lactone derivative(s) of our invention.
This invention further provides improved tobacco additives and methods whereby various desirable natural aromatic Turkish tobacco flavoring characteristics with oriental notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics.
In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more of the lactone derivative(s) of our invention.
In addition to the lactone derivative(s) of our invention, other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in admixture with the lactone derivative(s) of our invention as follows:
I. Synthetic Materials
Beta-ethyl-cinnamaldehyde;
Eugenol;
Dipentene;
Beta-damascenone;
Maltol;
Ethyl maltol;
Delta undecalactone;
Delta decalactone;
Benzaldehyde;
Amyl acetate;
Ethyl butyrate;
Ethyl valerate;
Ethyl acetate;
2-Hexenol-1;
2-Methyl-5-isopropyl-1,3-nonadiene-8-one;
2,6-Dimethyl-1,6-undecadiene-10-one;
2-Methyl-5-isopropyl acetophenone;
2-Hydroxy-2,5,5,8a-tetramethyl-1-(2-hydroxyethyl)decahydronaphthalene;
Dodecahydro-3a-6,6,9a-tetramethyl naphtho(2,1-b)furan;
4-Hydroxy hexanoic acid, gamma lactone; and
Polyisoprenoid hydrocarbons defined in Example V of U.S. Pat. No. 3,589,372 issued on June 29, 1971.
II. Natural Oils
Celery seed oil;
Coffee extract;
Bergamot oil;
Cocoa extract;
Nutmeg oil; and
Origanum oil.
An aroma and flavoring concentrate containing one or more of the lactone derivative(s) of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstitued tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of oriental and/or Turkish tobacco notes, we have found that satisfactory results are obtained if the proportion by weight of the sum total of lactone derivative(s) to smoking tobacco material is between 50 ppm and 1,500 ppm (0.005%-0.15%) of the active ingredients to the smoking tobacco material. We have further found that satisfactory results are obtained if the proportion by weight of the sum total of lactone derivative(s) used to flavoring material is between 500 and 15,000 ppm (0.05%-1.5%).
Any convenient method for incorporating the lactone derivative(s) into the tobacco product may be employed. Thus, the lactone derivative(s) taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, diethylether, and/or volatile organic solvents and the resulting solution may either be spread onto the cured, cased, and blended tobacco material or the toacco material may be dipped into such solution Under certain circumstances, a solution of the lactone derivative(s) taken alone or taken further together with other flavoring additives as set forth above may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying or dipping or coating.
Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus-treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have the lactone derivative(s) in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.
In accordance with one specific example of our invention, an aged, cured and shredded domestic Virginia tobacco is sprayed with a 20% alcohol solution of the compound having the structure: ##STR68## on a dry basis. Thereafter the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarette, when treated as indicated, has a desired and pleasing aroma which is detectable in the main stream and the side stream when the cigarette is smoked. This aroma is described as being sweeter, with pronounced Turkish/oriental characteristics and with improved body and enhanced tobacco character in the main stream and side stream. In addition, interesting amber nuances are imparted.
While our invention is particularly useful in the manufacture of smoking tobacco such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products formed from sheeted tobacco dust or fines may also be used. Likewise the lactone derivative(s) of our invention can be incorporated with materials such as filter tip materials, seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the lactone derivative(s) can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughout this specification, is meant any composition intended for human consumption by smoking or otherwise when composed of tobacco plant parts or substitute materials or both.

Gelatin is effected by pouring the heated coacervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulphate at 65° C. The resulting jelled coacervate may be filtered and washed with water at temperatures below the melting point of gelatin, to remove the salt.
Hardening of the filtered cake, in this example, is effected by washing with 200 parts by weight of 37% solution of formaldehyde in water. The cake is then washed to remove residual formaldehyde.

7.Description:
(en)This application is a continuation-in-part of application for United States Letters Patent, Ser. No. 228,512 filed on Aug. 5, 1988 now U.S. Pat. No. 4,946,782.
BACKGROUND OF THE INVENTION
This invention is concerned with a microbial process for the production of compositions of matter containing unsaturated lactones.
Considerable time and effort have been expended by microbiologists in the search for better processes for the production of unsaturated lactones; and more generally lactones per se. U.S. Pat. No. 3,076,750 discloses a method of preparing certain optically active lactones and the corresponding hydroxycarboxylic acids by microbial reduction of ketocarboxylic acids. The metabolism of ricinoleic acid by some Candida strains was investigated by Okui, et al (J.Biochemistry, 54,536-540, 1963) who showed that gamma hydroxydecanoic acid was an intermediate in the oxidative degradation of ricinoleic acid. However, only trace amounts of gamma hydroxydecanoic acid were recovered from the fermentation medium due to the metabolysis of gamma hydroxydecanoic acid upon completion of the fermentation, and the toxicity of ricinoleic acid to the microorganism, which limits the amount of substrate that can be used.
U.S. Pat. No. 4,560,656 provided a method of producing optically active gamma hydroxydecanoic acid comprising culturing or incubating a microorganism capable of hydrolyzing castor oil, and effecting beta-oxidation of the resulting hydrolysate in the presence of castor oil, to produce gamma hydroxydecanoic acid.
U.S. Pat. No. 4,560,656 also provided a method of producing optically active gamma hydroxydecanoic acid comprising enzymatically hydrolyzing castor oil using lipase to form an enzymatic hydrolysate and culturing or incubating a microorganizm capable of effecting beta-oxidation of the enzymatic hydrolysate in the presence of said hydrolysate to produce gamma hydroxydecanoic acid.
U.S. Pat. No. 4,560,656 also provided a method of producing optically active gamma hydroxydecanoic acid comprising culturing or incubating a microorganism capable of hydrolyzing castor oil and a microogranism capable of effecting beta-oxidation of castor oil hydrolysate in the presence of castor oil to produce gamma hydroxydecanoic acid.
European Published Patent Application 258993 published on Apr. 9, 1988 discloses a process for the production of optically active gamma hydroxydecanoic acid suitable for conversion to optically active gamma decalactone. The process covers steps of:
(a) culturing sporobolomyces odorous; and/or rhodotorula glutinis on a medium containing a ricinoleic acid sources at 15°-35° C. at a pH of 3-9 and optionally; and
(b) lactonizing the resulting gamma hydroxydecanoic acid to gamma decalactone.
Nothing in the prior art however discloses the ability by means of fermentation to create a novel mixture of unsaturated lactones together with, optionally, gamma decalactone found to be useful in augmenting or enhancing the organoleptic properties of consumable materials.
In the flavor and fragrance art, a need has arisen for the development and efficient production of naturally occurring lactones which have heretofor been found to be useful and necessary in the creation of flavor formulations used in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos and smoking tobaccos and also useful in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and the like).
Although U.S. Pat. No. 4,560,656 has partially fulfilled the need for provision of saturated gamma decalactone defined according to the structure: ##STR8## nothing in the prior art sets forth the creation of unsaturated lactones defined generically according to the structure: ##STR9## and defined more specifically according to the structures; ##STR10##

Referring to FIGS. 20 and 21, there is provided a process for forming scented polymer elements (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250° C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 20 and 21, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polyproyplene, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and the perfuming substance which is at least one of the lactones of our invention or mixtures of lactones and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostate or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds. The heater 218 is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220°-270° C. in the case of low density polyethylene. The bottom portion of the container 212 is heated by means of heating coils 212 A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220°-270° C.
Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the lactones of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.
After the perfume material is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coil 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the lactones of our invention or mixture of perfume substance and one or more of the lactones of our invention, will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240°-250° C., for example, (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer intimately admixed with the perfume substance which is all or which contains one or more of the lactones of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for the formation of other functional products, e.g., garbage bags and the like.
SUMMARY OF THE INVENTION
Our invention relates to a method using fermentation techniques to produce and recover certain naturally occurring lactones found to be useful for their organoleptic properties in augmenting or enhancing the aroma or taste of consumable materials such as foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, smoking tobaccos, perfume compositions, colognes and perfumed articles, e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, cosmetic powders, hair preparations and the like which lactones are defined according to the structures: ##STR53## and taken alone or taken further together with the lactone having the structure: ##STR54## wherein R represents C 6 alkyl or alkenyl, and X represents alkylene or alkenylene with the proviso that R is C 6 alkyl when X is alkenylene and R is C 6 alkenyl when X is alkenylene. The lactone compositions are produced by means of fermentation of castor oil or ricinoleic acid or a castor oil hydrolysate to form a mixture of carboxylic acids having the structure: ##STR55## together with gamma hydroxydecanoic acid according to the reaction: ##STR56## with the reaction of the castor oil going to the ricinoleic acid being shown, thusly: ##STR57## More specifically, the fermentation reaction of the ricinoleic acid going to the various carboxylic acids is shown according to the reaction: ##STR58## The fermentation reaction is effected as a result of the presence in the reaction mass of certain organisms, to wit, one of:
Candida petrophilum, ATCC 20226;
Candida oleophila, ATCC 20177;
Candida sp., ATCC 20504; or
Candida sake, ATCC 28137.
The resulting reaction mass is then subjected to a pH reduction to a pH in the range of 0-5 and heated at a temperature in the range of about 90° up to about 120° C. whereupon lactonization of the gamma hydroxydecanoic acid takes place, thusly: ##STR59## The other acids in the reaction mass do not lactonize.
The third step of the process of our invention involves distillation of the reaction mass at a temperature in the range of 120°-220° C. and at a pH of between about 1 and about 7 whereby the unsaturated acids lactonize according to the reaction: ##STR60## wherein the sum of the carbon atoms in the X moiety and in the R moiety is equal to the number of carbon atoms in the Y moiety minus 1 and wherein Y represents an oxo-saturated, oxo-unsaturated or di-unsaturated C 9 , C 11 or C 13 moiety.
The resulting products, in the form of mixtures of lactones or as separate lactones or groups of lactones are useful in augmenting or enhancing the aroma or taste of consumable materials as set forth, supra.
The first step of the process of our invention involving the reactions: ##STR61## takes place at a pH in the range of 5.5 up to 7 and a temperature in the range of from about 20° up to about 35° C.
Prior to the reaction taking place an inoculum is produced whereby the microorganism, e.g., Candida petrophilum, ATCC 20226 is grown in olive oil for a period of about 10 up to about 30 hours. The resulting inoculum is then admixed with castor oil or a castor oil hydrolysate substrate.
The form in which the microorganisms are used is not critical. They can be used as the culture (suspension), i.e., including the cells and the corresponding nutrient solution, or in the form of cells suspended in a buffer solution. The cells or an enzyme extract thereof may be immobilized on a suitable solid support which may then be used to effect the transformations
The culture suspension is prepared by inoculation of a suitable medium with the microorganism. A suitable medium is one which contains carbon sources, nitrogen sources, inorganic salts and growth factors. Among the suitable carbon sources are for example, glucose, galactose, L-sorbose, maltose, sucrose, cellobiose, trehalose, L-arabinoise, L-rhamnose, ethanol, glycerol, L-erythrithol, D-mannitol, lactose, melibiose, raffinose, meleitose, starch, D-xylose, D-sorbitol, alpha-methyl-D-glucoside, lactic acid, citric acid and succinic acid. Among the suitable nitrogen sources are, for example, nitrogen-containing organic substances such as peptone, meat extract, yeast extract, corn steep liquor, and casein, urea, amino acids, or nitrogen containing inorganic compounds such as nitrates, nitrites, and inorganic ammonium salts. Among the suitable inorganic salts are, for example, phosphates, magnesium, potassium, calcium, sodium. The above mentioned nutrients in the culture medium may be supplemented with, for example, one or more vitamins of the B Group and/or one or more trace minerals such as Fe, Mo, Cu, Mn, B as desired. However, the process can be performed in a vitamin-free medium; for example, when a small amount of yeast extract is added to the medium there is no need for vitamins or trace minerals.
The cultivation of the microorganism can be carried out as a stationary culture or as a submerged culture (e.g., shaking culture, fermentors) preferably under aerobic conditions. One suitably may work in the pH range of from about 3.5 to about 8.0, and preferably in the range of from about 4.0 to about 7.5. The pH may be regulated by the addition of inorganic or organic bases, such as sodium hydroxide, potassium hydroxide, calcium hydroxide, calcium carbonate, by ion-exchange resins, or by the addition of a buffer such as phosphate or phthalate. The incubation temperature is suitably maintained at between about 15° C. and about 33° C., with a range from about 20° C. to about 30° C. being preferred.
The process in accordance with the invention is conveniently carried out by adding castor oil or castor oil hydrolysate, as the substrate, to the culture medium at the onset of cultivation, as the sole carbon source. Alternatively, the substrate may be added in combination with another carbon source, such as dextrose, either during cultivation, or when cultivation is complete. The amount level, or concentration of the substrate in the medium may vary. For example, in the case of hydrolyzed castor oil, levels of from about 0.3% to about 5% may make up the medium initially or be added during the course of the fermentation, whereas substantially any level of castor oil may be used. The reaction time may vary depending on the composition of the culture medium and the substrate concentration. In general, shaking flask cultures require from between about 2h. and about 240h. depending upon the microorganism and the composition of the culture medium. However, when a fermentor is used the fermentation time may be reduced to about 100h. or less
The fermentation may be carried out using the cells of the microorganism isolated from the culture solution, or with an enzyme extract isolated from the cells in a manner known per se In this case, the fermentation can be conveniently carried out in aqueous solution, for example, in a buffer solution, in a physiological salt solution, in a fresh nutrient solution, or in water. The isolated cells or enzyme extract may be immobilized on a solid support and the desired transformation effected in the absence of the live microorganism. The transformation of the substrate may be effected by mutants of the microorganism. Such mutants can be obtained readily by methods well known in the art, for example, by exposing the cells to UV or X-rays, or customary mutagenic substances such as, for example, acridine orange.
The substrate is generally added directly to the medium. A surface-active agent or dispersion agent, such as TWEEN® 80 polyoxyethylenesorbitan monostearate), can also be added to an aqueous suspension of the substrate. Conventional antifoam agents, such as silicone oils (e.g., UCON), polyalkyleneglycol derivatives, maize oil, or soya oil can be used to control foaming.
The transformation of the substrate can be monitored using standard analytical techniques such as GLC, TLC, HPLC, IR and NMR. If a rapid disappearance of the substrate is observed, more substrate can then be added in order to maximize the transformation capacity of the microorganisms. The incubation is generally terminated when all the substrate has disappeared from the culture medium.
After the fermentation process is complete, the lactonization steps may take place. The first lactonization, involving the reaction of gamma hydroxydecanoic acid, to wit: ##STR62## takes place at a pH in the range of 0-5 at a temperature of 90°-120° C. The pH is adjusted using acids such as 85% aqueous phosphoric acid. The reaction time may vary from about 0.25 hours up to about 2 hours. During this first lactonization step the unsaturated carboxylic acids defined according to the structure: ##STR63## e.g., the carboxylic acids having the structures: ##STR64## do not lactonize.
However, when the resulting mixture containing the gamma decalactone having the structure: ##STR65## is distilled at 120°-220° C. while the pH of the reaction mixture is in the range of 1-7 lactones having the structures: ##STR66## are produced according to the reactions: ##STR67##
The lactone derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters other than the lactone derivatives of our invention, ethers, synthetic essential oils, and natural essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the fruity area (e.g., peach and apricot aromas). Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation and (d) topnotes which are usually low-boiling, fresh-smelling materials.
In perfume compositions, it is the individual compositions which contribute to their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the lactone derivative(s) of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of lactone derivative(s) of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.005% of lactone derivative(s) or even less (e.g., 0.002%) can be used to impart sweet, fruity (peach and apricot) aromas to soaps, cosmetics, detergents including anionic, cationic, nonionic and zwitterionic solid or liquid detergents, perfumed polymers and other products. The amount employed can range up to 70% of the fragrance components and will depend upon the consideration of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
The lactone derivative(s) of our invention are useful (taken alone or taken together with other ingredients in perfume compositions) in detergents, soaps, space odorants and deodorants, perfumes, colognes, toilet waters, bath preparations, hair preparations such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like.
As little as 0.25% of the lactone derivative(s) will suffice to impart an intense, sweet, fruity (peach and apricot) aroma to floral perfume formulations. Generally no more than 5% of the lactone derivative(s) based on the ultimate end product is required to be used in the perfume compositions.
Furthermore, as little as 0.25% of the lactone derivative(s) will suffice to impart such aromas to perfumed articles per se, whether in the presence of other perfume materials or whether used by themselves. Thus, the range of use of the lactone derivative(s) of our invention in perfumed articles, e.g., perfumed polymers and solid or liquid anionic, cationic, nonionic or zwitterionic solid or liquid detergents, may vary from 0.25% up to about 5% by weight based on the total weight of the perfumed article.
In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the lactone derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethanol, a non-toxic glycol, e.g., propylene glycol, or the like. The carrier can also be an absorbent solid such as a gum (e.g., gum arabic or xanthan gum or guar gum) or components for encapsulating the composition by means of coacervation (such as by gelatin) or by means of formation of a polymer around a liquid center (as by using a urea formaldehyde prepolymer to form a polymeric capsule around a perfume composition center).
It will be appreciated from the present disclosure that the lactone derivatives according to the present invention can be used to alter, vary, fortify, modify, enhance or otherwise improve the flavor of a wide variety of materials which are ingested, consumed or otherwise organoleptically sensed.
The terms "alter" and "modify" in their various forms will be understood herein to mean the supplying or imparting of a flavor character or note to an otherwise bland, relatively tasteless substance, or augmenting an existing flavor characteristic where the natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its organoleptic character.
The term "enhance" is intended herein to mean the intensification (by use of the lactone derivative of our invention) of a flavor or aroma note or nuance in a tobacco flavor or foodstuff or perfume composition or perfumed article without changing the quality of said note or nuance.
A "flavoring composition" is taken to mean one which contributes a part of the overall flavor impression by supplementing or fortifying a natural or artifical flavor in a material or one which supplies substantially all the flavor and/or aroma character to a consumable article.
The term "foodstuff" as used herein includes both solid and liquid ingestible materials for man or animals which materials usually do, but need not, have nutritional value. Thus, foodstuffs include meats, gravies, soups, convenience foods, malt, alcoholic and other beverages, milk and dairy products, seafoods, including fish, crustaceans, mollusks and the like, candies, vegetables, cereals, soft drinks, snacks, dog and cat foods, other veterinary products, and the like. The lactone derivative(s) of our invention are also useful tobacco flavorants and flavor enhancers.
The term "tobacco" will be understood herein to mean natural products such as, for example, burley, Turkish tobacco, Maryland tobacco, flue-cured tobacco and the like including tobacco-like or tobacco-based products such as reconstituted or homogenized leaf and the like as well as tobacco substitutes intended to replace natural tobacco such as lettuce and cabbage leaves and the like. The tobaccos and tobacco products in which the lactone derivative(s) of our invention are useful include those designed or used for smoking such as in cigarettes, cigar and pipe tobacco, as well as products such as snuff, chewing tobacco and the like.
When the lactone derivative(s) of this invention are used in a flavoring composition, they can be combined with conventional flavoring materials or adjuvants. Such co-ingredients or flavoring adjuvants are well known in the art for such and have been extensively described in the literature. Requirements of such adjuvant materials are: (1) that they be non-reactive with the lactone derivative(s) of our invention; (2) that they be organoleptically compatible with the lactone derivative(s) of our invention whereby the flavor of the ultimate consumable material to which the lactone derivative(s) are added is not detrimentally affected by the use of the adjuvant; (3) that they be ingestibly acceptable and thus non-toxic or otherwise non-deleterious. Apart from these requirements, conventional materials can be used and broadly include other flavor materials, vehicles, stabilizers, thickeners, surface active agents, conditioners, and flavor intensifiers.
Such conventional flavoring materials include saturated fatty acids, unsaturated fatty acids and amino acids; alcohols including primary and secondary alcohols, esters, carbonyl compounds including ketones and aldehydes; lactones; other cyclic organic materials including benzene derivatives, allicyclic compounds, heterocyclics such as furans, pyridines, pyrazines and the like; sulfur-containing compounds including thiols, sulfides, disulfides and the like; proteins; lipids, carbohydrates; so-called flavor potentiators such as monosodium glutamate, magnesium glutamate, calcium glutamate, guanylates and inosinates; natural flavoring materials such as cocoa, vanilla and caramel; essential oils and extracts such as anise oil, clove oil and the like and artificial flavoring materials such as vanillin and the like.
Specific preferred flavor adjuvants are as follows:
anise oil;
ethyl-2-methyl butyrate;
vanillin;
cis-3-heptenol;
cis-3-hexenol;
trans-2-heptenol;
cis-3-heptenal;

2,4-decadienal;
2,4-haptadienal; and
butylidene phthalide.
According to another aspect of our invention, an organoleptically improved smoking tobacco product and additives therefor as well as methods of making the same which overcome specific problems heretofore encountered in which specific Turkish, oriental-like aromas prior to smoking and improved Turkish, oriental aromas on smoking in the main stream and the side stream are created or enhanced or modified or augmented and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend. In particular, low grade Virginia-type tobaccos may be upgraded using the lactone derivative(s) of our invention.
This invention further provides improved tobacco additives and methods whereby various desirable natural aromatic Turkish tobacco flavoring characteristics with oriental notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics.
In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more of the lactone derivative(s) of our invention.
In addition to the lactone derivative(s) of our invention, other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in admixture with the lactone derivative(s) of our invention as follows:
I. Synthetic Materials
Beta-ethyl-cinnamaldehyde;
Eugenol;
Dipentene;
Beta-damascenone;
Maltol;
Ethyl maltol;
Delta undecalactone;
Delta decalactone;
Benzaldehyde;
Amyl acetate;
Ethyl butyrate;
Ethyl valerate;
Ethyl acetate;
2-Hexenol-1;
2-Methyl-5-isopropyl-1,3-nonadiene-8-one;
2,6-Dimethyl-1,6-undecadiene-10-one;
2-Methyl-5-isopropyl acetophenone;
2-Hydroxy-2,5,5,8a-tetramethyl-1-(2-hydroxyethyl)decahydronaphthalene;
Dodecahydro-3a-6,6,9a-tetramethyl naphtho(2,1-b)furan;
4-Hydroxy hexanoic acid, gamma lactone; and
Polyisoprenoid hydrocarbons defined in Example V of U.S. Pat. No. 3,589,372 issued on June 29, 1971.
II. Natural Oils
Celery seed oil;
Coffee extract;
Bergamot oil;
Cocoa extract;
Nutmeg oil; and
Origanum oil.
An aroma and flavoring concentrate containing one or more of the lactone derivative(s) of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstitued tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of oriental and/or Turkish tobacco notes, we have found that satisfactory results are obtained if the proportion by weight of the sum total of lactone derivative(s) to smoking tobacco material is between 50 ppm and 1,500 ppm (0.005%-0.15%) of the active ingredients to the smoking tobacco material. We have further found that satisfactory results are obtained if the proportion by weight of the sum total of lactone derivative(s) used to flavoring material is between 500 and 15,000 ppm (0.05%-1.5%).
Any convenient method for incorporating the lactone derivative(s) into the tobacco product may be employed. Thus, the lactone derivative(s) taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, diethylether, and/or volatile organic solvents and the resulting solution may either be spread onto the cured, cased, and blended tobacco material or the toacco material may be dipped into such solution Under certain circumstances, a solution of the lactone derivative(s) taken alone or taken further together with other flavoring additives as set forth above may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying or dipping or coating.
Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus-treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have the lactone derivative(s) in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.
In accordance with one specific example of our invention, an aged, cured and shredded domestic Virginia tobacco is sprayed with a 20% alcohol solution of the compound having the structure: ##STR68## on a dry basis. Thereafter the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarette, when treated as indicated, has a desired and pleasing aroma which is detectable in the main stream and the side stream when the cigarette is smoked. This aroma is described as being sweeter, with pronounced Turkish/oriental characteristics and with improved body and enhanced tobacco character in the main stream and side stream. In addition, interesting amber nuances are imparted.
While our invention is particularly useful in the manufacture of smoking tobacco such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products formed from sheeted tobacco dust or fines may also be used. Likewise the lactone derivative(s) of our invention can be incorporated with materials such as filter tip materials, seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the lactone derivative(s) can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughout this specification, is meant any composition intended for human consumption by smoking or otherwise when composed of tobacco plant parts or substitute materials or both.

A second flavor formulation is prepared which is identical to the above formulation, except without the lactones of Example V.
The flavor formulation with the lactones of Example V has a definite natural rich orange aroma with buttery nuances due to the addition of the buttery principals to this citrus flavor.
The citrus flavor with the lactones of Example V added thereto is used in the following examples.
EXAMPLE XXI
A. Powder Flavor Composition
20 Grams of the flavor composition of Example XX containing the lactones of Example V is emulsified in a solution containing 300 grams gum acacia and 700 grams water. The emulsion is spray-dried with a Bowen Lab Model Drier utilizing c.f.m. of air with an inlet temperature of 500° F., an outlet temperature of 200° F., and a wheel speed of 50,000 rpm.
B. Sustained Release Flavor
The following mixture is prepared:
______________________________________Ingredients Parts by Weight______________________________________Liquid Citrus Flavor 20.0Composition of Example XXPropylene glycol 9.0CAB-O-SIL ® M-5 5.00(Brand of Silica produced by theCabot Corporation of 125 High Street,Boston, Massachusetts 0210):Physical Properties:Surface area: 200 m.sub.2 /gmNominal particle size: 0.012 micronsDensity: 2.3 lbs/cu.ft.)______________________________________
The Cab-O-Sil is dispersed in the liquid citrus flavor composition of Example XX with vigorous stirring, thereby resulting in a viscous liquid. 71 Parts by weight of the powder flavor composition of Part "A", supra, is then blended into the said viscous liquid, with stirring, at 25° C. for a period of 30 minutes resulting in a dry, free flowing sustained release flavor powder.
EXAMPLE XXII
10 Parts by weight of 50 Bloom pigskin gelatin is added to 90 parts by weight of water at a temperature of 150° F. The mixture is agitated until the gelatin is completely dissolved and the solution is cooled to 120° F. 20 Parts by weight of the liquid flavor composition of Example XX is added to the solution which is then homogenized to form an emulsion having particle size typically in the range of 5-40 microns. This material is kept at 120° F. under which conditions the gelatin will not jell.
Coacervation is induced by adding, slowly and uniformly 40 parts by weight of a 20% aqueous solution of sodium sulphate. During coacervation the gelatin molecules are deposited uniformly about each oil droplet as a nucleus.
Gelatin is effected by pouring the heated coacervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulphate at 65° C. The resulting jelled coacervate may be filtered and washed with water at temperatures below the melting point of gelatin, to remove the salt.
Hardening of the filtered cake, in this example, is effected by washing with 200 parts by weight of 37% solution of formaldehyde in water. The cake is then washed to remove residual formaldehyde.
EXAMPLE XXIII
Chewing Gum
100 Parts by weight of chicle are mixed with 4 parts by weight of the flavor prepared in accordance with Example XXI(B) 300 Parts of sucrose and 100 parts of corn syrup are added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Company.
The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long-lasting rich citrus flavor.
EXAMPLE XXIV
Chewing Gum
100 Parts by weight of chicle are mixed with 18 parts by weight of the flavor prepared in accordance with Example XXII. 300 Parts of sucrose and 100 parts of corn syrup are then added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Company.
The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long-lasting rich citrus flavor.
EXAMPLE XXV
Toothpaste Formulation
The following separate groups of ingredients are prepared:
