Abstract
Abstract Processes for imparting flavors and aromas to consumable materials, for example vegetable flavors to foodstuffs or perique flavors to tobacco, by adding to such materials a small amount of at least one thioester according to the formula: ##STR1## wherein R 1 is alkyl, aryl, aralkyl, alkaryl, cycloalkyl, or alkenyl and R 2 is alkyl, alkylthioalkyl, aralkyl, alkaryl, or aryl, R 1 containing at least two carbon atoms when R 2 is an alkyl group containing three or four carbon atoms, effective to alter the flavor and/or aroma of such materials, together with compositions containing such thioesters and adapted to alter the flavor and/or aroma of such materials, novel cycloalkyl and alkenyl thiopropionates useful for such purposes, and processes for producing such novel thiopropionates.
