Usee

Isobutyl butyrate is a metabolite of Rifampicin, a Rifamycin antibiotic.

Description

Isobutyl butyrate has a fruity odor reminiscent of apple or pineapple and a sweet flavor reminiscent of rum. May be prepared by esterification of butyric acid with isobutyl alcohol in the presence of concentrated H2S04; or by enzymatic action of hog pancreas on a mixture of isobutyl alcohol and butyric acid in the absence of water.

Chemical Properties

Isobutyl butyrate has a fruity, ethereal odor reminiscent of apple or pineapple and a sweet flavor reminiscent of rum.

Definition

ChEBI: A butyrate ester resulting from the formal condensation of butanoic acid with isobutanol. It is used as a food flavour ingredient for apple, banana, peach and pinapple flavours in ice cream and confectionery.

Preparation

By esterification of butyric acid with isobutyl alcohol in the presence of concentrated H2SO4, or by enzymatic action of hog pancreas on a mixture of isobutyl alcohol and butyric acid in the absence of water.

Taste threshold values
