Organoleptic compositions

摘要

The present invention provides organoleptic compositions which upon thermolyis, hydrolysis or both, release an odorant molecule. They find utility, for example, in tobacco, in tobacco paper, and as additives to food, beverages or gum. The compositions contain one or more dicarboalkoxy dioxolane derivatives having the following formula: <IMAGE> wherein R1 and R2 are, independently, -CO2R3 wherein R3 is -H3 or lower alkyl, provided that in at least one of R1 and R2, R3 is lower alkyl; wherein Z is a direct bond, or -CH=C(R4)-; where R4 is -H or alkyl group; and Y is <IMAGE> where R5 and R6 are independently -H, lower alkyl or -OR7 where R7 is -H or lower alkyl.
