ABSTRACT:
A process is provided for the treatment of tobacco which comprises the steps of: (1) contacting tobacco which contains relatively high quantities of desirable flavorants, and which may also contain relatively high quantities of materials which may produce tar and nicotine in the tobacco smoke, for example, a flavorful bright tobacco, with a stream of non-reactive gas, under conditions whereby the tobacco is heated in a temperature range from about 140.degree. to about 180.degree. C., and preferably from about 160.degree. to about 170.degree. C., for a period of time sufficient to result in a weight loss of the tobacco of from about 3 to about 10% in excess of the weight loss represented by oven volatiles as defined herein, (2) condensing volatile constituents of the resulting gaseous stream, for example, by passing the gaseous stream in contact with a surface, maintained at a temperature of from about -78.degree. C. or lower to about 30.degree. C., for sufficient time to form a condensate; and (3) collecting said condensate. The condensate may be used subsequently to flavor a smoking material in order to enhance the organoleptic properties of its smoke.
