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: WHEREIN R1 is alkyl, aryl, aralkyl, alkaryl, cycloalkyl, or alkenyl and R2 is alkyl, alkylthioalkyl, aralkyl, alkaryl, or aryl, R1 containing at least two carbon atoms when R2 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.
