Definitions

• TUBACCU PRUDUCT This invention relates to a tobacco product and has for an object the provision of a composition for improving the flavor and/or aroma of tobacco and tobacco smoke.
• a further object of this invention is the provision of an additive 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.
• An additional object of this invention is to provide a product which when smoked has an enhanced flavor or aroma.
• a still further object of this invention is the provision of smoking products, such as cigarettes, cigars or pipe tobacco, whereby the flavor and aroma before and during smoking are improved or enhanced.
• the flavor and/or aroma of tobacco or tobacco products is improved by adding thereto a small amount of a pyridine compound having from one to three lower alkyl substituents therein. More particularly, the tobacco additives are pyridines substituted with from one to three methyl or ethyl groups.
• tobacco additives are: 3-methylpyn'dine, 3,4-dimethylpyridine, 3,5- dimethylpyridine, 2,4-dimethylpyridine, 2,5-dimethylpyridine, 2,6-dimethylpyridine, 2-ethylpyridine, 4-methylpyridine, 3-ethylpyridine, 4-ethylpyridine, 4-ethyl-2-methyl pyridine, 3-ethyl-4-methylpyridine and 2,4,6-trimethylpyridine.
• Preparation of the alkyl substituted pyridines employed in accordance with this invention is known to the art.
• an alkyl substituted pyridine 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 0.05 percent by weight of the tobacco or tobacco product.
• the amount of additive is between about 0.0001 and 0.001 percent by weight.
• 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.
• 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.
• tobacco additives of the invention when incorporated into tobacco products improve the flavor and/or aroma of the product.
• 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.
• an aged flue-cured and shredded tobacco is sprayed with a 1 percent ethyl alcohol solution of 3-methylpyridine in an amount to provide a tobacco containing 0.00l percent by weight of the additive on a dry basis. Thereafter the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. It has been found that the cigarette when prepared as indicated has an improved burley character.
• 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.
• 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.
• other flavorand aroma-producing additives such as those disclosed in US. 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.
• the additives can be added to certain tobacco substitutes of natural or synthetic origin 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.
• the invention has been particularly described with reference to the addition of the additives directly to tobacco.
• 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 material or the seam paste employed for gluing the cigarette paper.
• 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.
• a tobacco product having added thereto a small amount of an alkyl substituted pyridine compound having the pyridine nucleus and having as the only substituents thereon from one to three alkyl groups selected from methyl and ethyl, said amount being not more than about 0.00l percent by weight of the tobacco product and being sufficient to alter the flavor or aroma of the tobacco product.
• a product in accordance with claim 1 pyridine compound is 4-methylpyridine.
• a product in accordance with claim 1 pyridine compound is 3-ethylpyridine.
• a product in accordance with claim 1 pyridine compound is 4-ethylpyridine.
• a product in accordance with claim 1 pyridine compound is 4-ethyl-2-methylpyridine.
• a product in accordance with claim I pyridine compound is 3-ethyl4-methylpyridine.
• a product in accordance with claim 1 pyridine compound is 2,4,6-trimethylpyridine.
