3,095,882 7/1963 Hind c121]. l3l/l7 R 5 Claims, N0 Drawings 7 TOBACCO PRODUCT This invention relates to tobacco and tobacco products and has for an object the provision of compositions and processes for improving the flavor and/or aroma of tobacco and tobacco smoke.
it is well known in the tobacco art that the flavor and aroma of tobacco products and the smoke from the tobacco are very important considerations insofar as the ultimate consumer is concerned. Considerable efforts are exerted by the manufacturers of tobacco products to provide a product that will be acceptable to the consumer, particularly as regards flavor and aroma characteristics. It has been the common practice in the tobacco industry to prepare blends of domestic and oriental tobaccos in order to provide smoking tobacco which has a pleasing flavor and aroma before and during smoking. However, such a procedure is costly and may at times become prohibitive in the event that certain types of tobacco may be in short supply. Accordingly, it is a further object of this invention to provide a class of additive materials which when applied to the tobacco products improve and enhance the flavor and aroma of these products and the smoke emitted therefrom thereby increasing or enhancing the pleasure and other values that may be derived by the comsumer from the use of these products.
A further object of this invention is the provision of processes for enhancing or otherwise improving the flavor, aroma and other qualities of certain domestic, oriental, reconstituted or synthetic tobaccos which may be deficient in said flavor or aroma or other qualities.
A still further object of this invention is the provision of smoking products, such as cigarettes, cigars or pipe tobacco, and a process for forming same whereby the flavor and aroma before and during smoking are improved or enhanced.
Further and additional objects will appear from the following description and the appended claims.
In accordance with this invention, the flavor and/or aroma of tobacco or tobacco products is improved by adding thereto a small amount of a compound having the following general formula:
wherein R alkyl of up to eight carbon atoms, alkenyl of up to 8 carbon atoms, cycloalkyl of not more than 6 carbon atoms, cycloalkenyl of five or six carbon atoms;
R hydrogen or alkyl of up to six carbon atoms;
R, hydrogen or alkyl of up to six carbon atoms; or
R and R together alkylidenyl of up to eight carbon atoms.
Representative ofthe tobacco additives ofthis invention are: methylsuccinic anhydride, ethylsuccinic anhydride, isopropylsuccinic anhydride, octylsuccinic anhydride, 2,2-dimcthylsuccinic anhydride, 2,3-dimethylsuccinic anhydride, 2-ethyl-3-met-hylsuccinic anhydride, 2-butyl-2-ethylsuccinic anhydride, 2-butyl-3-hexylsuccinic anhydride, 2,3-dihexylsuccinic anhydride, 2,2-dipropylsuccinic anhydride, 2,3-di-tertbutylsuccinic anhydride, 2,3-diethyI-Z-methylsuccinic anhydride, 2-ethyl-2,3-dimethylsuccinic anhydride, trimethylsuccinic anhydride, allylsuccinic anhydride, (2-ethyl-l-butenyl)succinic anhydride, hexenylsuccinic anhydride, octenylsuccinic anhydride, (2-neopentylallyl)succinic anhydride, cyclopentylsuccinic anhydride, cyclohexylsuccinic anhydride, cyclopentenylsuccinic anhydride, cyclohexenylsuccinic anhydride, itaconic anhydride, ethylidenylsuccinic anhydride, isopropylidenylsuccinic anhydride, l-methylheptylidene )succinic anhydride and cyclohexylidenylsuccinic anhydride.
The tobacco additives of this invention'are known compounds as are methods of preparing them.
In practice of this invention a compound of the class described or mixtures thereof is added to tobacco or applied to a tobacco product or its component parts in amounts of from about 0.00001 to about 0.1 percent by weight of the tobacco or tobacco product. Preferably, the amount of additive is between about 0.0005 and 0.005 percent by weight. However, the amount used will depend upon the amount of flavor and/or aroma desired and the particular compound or mixtures thereof that is used. The additives can be incorporated at any step in treatment of the tobacco but are preferably added after aging, curing and shredding and before the tobacco is formed into cigarettes or other products. Likewise, it will.be apparent that only a portion of the tobacco need be treated and the thus treated tobacco can be blended with other tobaccos before the cigarettes or other tobacco products are formed. In such case the treated tobacco may have the additive in excess of the amounts above indicated so that when blended with other tobaccos the final product will contain a percentage of additive within the indicated range.
The tobacco additives of the invention when incorporated into tobacco products improve the flavor and/or aroma of the product. However, it is to be appreciated that definition or characterization of flavor or aroma in the tobacco art is almost purely subjective and different smokers may define the same flavor or effect quite differently. With this in mind, characterization of the effect of representative tobacco additives-of this invention in cigarettes has been made as follows:
Additive 2,2-Dimethylsuccinic anhydride 2,3-Dimethylsuccinic anhydride Octylsuccinic anhydride [sopr'opylsuccinic anhydride Flavor Evaluation Adds harshness Sweet, adds harshness and body Adds body. burley character Sweet. nutty, fruity, some Oriental character Sweet, smoothing. enhances itaconic anhydride tobacco flavor. adds body Z-EthyI-J-methylsuccinic anhydride slightly chemical smoked.
Sweet. adds richness. green taste.
The additives falling within the scope of this invention may be applied to the tobacco by spraying, dipping or otherwise, utilizing suitable suspensions or solutions of the additives. Thus, water or volatile organic solvents, such as alcohol, ether, acetone, volatile hydrocarbons and the like, may be used as the carrying medium for the additives while being applied to the tobacco. Also, other flavorand aroma-producing additives, such as those disclosed in U.S. Pat. Nos. 2,766,145, 2,905,575, 2,905,576, 2,978,365 and 3,041,211 may be incorporated into the tobacco with the additives of this invention.
While this invention is principally useful in the manufacture of cigarette tobacco, it is also suitable for use in connection with the manufacture of pipe tobacco, cigars or other tobacco products. Furthermore, the additives can be added to certain tobacco substitutes of natural or synthetic origin and by the term tobacco as used throughout this specification is meant any composition intended for use by smoking or otherwise, whether composed of tobacco plant parts or substitute materials or both.
Also, the invention has been particularly described with reference to the addition of the additives directly to tobacco. However, it will be apparent that the additives can be applied to the paper of the cigarette or to the wrapper of a cigar. Also, they can be incorporated into the filter tip, the packaging materialor the seam paste employed for gluing the cigarette paper. Thus, a tobacco product is provided which includes the specified additives and tobacco although in every instance the compound need not be admixed with the tobacco as above specifically described.
Those modifications and equivalents which fall within the spirit of the invention-are to be considered a part thereof.
