| Hazard Information | Back Directory | [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]
Taste characteristics at 20 ppm: sweet, fruity, pineapple, apple, bubble gum and tutti-frutti.
Natural occurrence: Reported found in apricot, banana, apple, strawberry, blue and Gruyere cheeses, cognac, port wine, rum,
