ABSTRACT:
Described is a process for the preparation of C.sub.2 -C.sub.5 alkyl esters of C.sub.4 -C.sub.5 carboxylic acids defined according to the structure: ##STR1## by means of fermentation of one or more C.sub.5 -C.sub.6 amino acids defined according to the structure: ##STR2## in the presence of a C.sub.2 -C.sub.5 alcohol according to the reaction: ##STR3## wherein R.sub.1, R.sub.2 and R.sub.3 each represent hydrogen or methyl with the proviso that at least one of R.sub.1, R.sub.2 and R.sub.3 represents methyl and wherein R represents C.sub.2 -C.sub.5 alkyl and wherein R is the same as R'. Also described are the products produced according to such process as well as their organoleptic utilities for augmenting or enhancing the aroma or taste of consumable materials selected from the group consisting of perfume compositions, colognes, perfumed articles, foodstuffs, chewing gums, medicinal products, toothpaste, chewing tobaccos and smoking tobaccos.
