Abstract of the Disclosure The invention provides a process for treating a consumable material which comprises adding thereto a small but effective amount of at least one bicyclo-[2.2.2]-octane derivative having the formula wherein the dashed lines represent single or double carbon-to-carbon bonds, but when the dashed line between R7 and R8 is a single bond then the dashed line between R9 and R10 is a single bond; one of R2 or R3 is hydrogen or lower alkyl and the other is hydrogen or hydroxy, or taken together, R2 and R3 are a carbonyl oxygen; R4 and R5 are lower alkyl; R1, R6, R7 and R8 are hydrogen or lower alkyl; R9 is hydrogen, lower alkyl other than isobutyl, cyano, lower carboalkoxy or lower aliphatic acyl other than acetyl, and R10 is hydrogen, lower alkyl, cyano, lower carboalkoxy, or lower aliphatic acyl of 3 or more carbon atoms, at least one of R9 and R10 being hydrogen, at least five of R1 through R10 being other than hydrogen, to alter the organo-leptic properties of the material and particularly the aroma. The novel bicyclo-[2.2.2]-octane derivatives and processes for preparing them are also disclosed. |
