General description

Isoamyl acetate is the major ginjo-flavor components of Japanese sake (Ginjo-shu). It is effective in inactivating various microorganisms. Synthesis of isoamyl acetate by lipase-catalyzed transesterification of ethyl acetate in n-hexane has been reported. It is flavor-active compound present in beer.
