Definitions

• An additional object of this invention is to provide a tobacco which has been treated in such manner as to impart a subtle flavor which is pleasing to the smoker.
• a domestic tobacco is provided to which has been added a small amount of l-methyl-Z-pyrrolecarboxaldehyde.
• the above chemical herein referred to as Compound I, may be represented by the followingformula:
• Compound I is a liquid having a boiling point of approximately 72.4 C. per 12 millimeters of mercury pressure and the following characteristics:
• the designated Compound I is usually added to a domestic tobacco in amounts to provide a tobacco in which is dispersed about 0.001 to about 1.0 percent by weight of the additive.
• the amount of additive is between about 0.005 and about 0.03 percent by weight in order to form a domestic tobacco having a desired flavor and aroma.
• the preferred percentages may be somewhat less, however, if
• the additive may be applied in any suitable manner and preferably in the form of a liquid solution or suspension by spraying, dipping or otherwise.
• the additive may be incorporated at any step in the treatment of the tobacco, but is preferably added after aging, curing and shredding and before the tobacco is formed into cigarettes.
• the tobacco treated may have the additive in excess of the amounts above indicated so that when blended with other tobaccos the final product will have the percentage within the indicated range.
• an aged, cured and shredded burley tobacco is sprayed with a one percent ethyl alcohol solution of the above indicated compound in an amount to provide a to bacco composition containing 0.01 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.
• the cigarette when treated as indicated has a desired and pleasing aroma which is detectable in the main and side smoke streams when the cigarette is smoked; this aroma is described by some smokers as an almond note.
• the manner in which the additive is applied to the tobacco is not particularly important since, as indicated, it may be done in the form of spraying or dipping, utilizing suitable suspensions or solutions of the additive.
• water or volatile organic solvents such as alcohol, ether, acetone, volatile hydrocarbons and the like, may be used as the carrying medium for the additive while it is being applied to the tobacco.
• other flavor and aroma producing additives such as those disclosed in Jones United States Patent No. 2,766,145 and Schumacher United States Patent No. 2,978,365, may be incorporated into the tobacco with the additive of this invention.
• the additives of the 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.
• the additive of this invention 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 human consumption by smoking or otherwise, Whether composed of tobacco plant parts or substitute materials or both.
• a domestic tobacco having added thereto a small amount of 1-methyl-2-pyrrolecarboxaldehyde suflicient to alter the flavor of the tobacco.
• a domestic smoking tobacco having added thereto between about 0.001 and about 1.0 percent by Weight of 1-methy1-2-pyrrolecarboxaldehyde.
• a domestic smoking tobacco having added thereto between about 0.005 and about 0.03 percent by weight of 1-methyl-2-pyrrolecarboxaldehyde.
• a tobacco product having added thereto a small amount of 1-methyl-2-pyrrolecarboxalde'hyde sufiicient to improve the flavor of the tobacco.
• a tobacco product having added thereto between 3 about 0.001 and about 1.0 percent by weight of l-methyl- 2-pyrrolecarboxaldehyde.
• a tobacco product having added thereto between about 0.005 and about 0.03 percent by weight of l-methyl-2-pyrrolecarboxaldehyde.
• a tobacco substitute having added thereto between about 0.001 and about 1.0 percent by weight of l-methyl- 2-pyrrolecarboxaldehyde.
• a process of improving tobacco which comprises adding thereto a small amount of 1-methyl-2-pyrrolecarboxaldehyde suflicient to improve the flavor of the tobacco.
• a process of improving the flavor of tobacco which comprises adding thereto between about 0.001 and about 1.0 percent of 1-methyl-2-pyrrolecarboxaldehyde.
• a process of improving tobacco which comprises adding thereto in the form of a liquid solution a small amount of 1-methyl-2-pyrrolecarboxaldehyde sufficient to improve the flavor of the tobacco.
• a process of improving tobacco which comprises adding thereto in the form'of a liquid suspension a small amount of 1-methyl-2-pyrrolecarboxaldehyde suflicient to improve the flavor of the tobacco.
