설명

일반 설명

Isobutyl acetate, a medium chain ester, is a high-volume solvent, flavor and fragrance compound. It is the fruity ester formed during the fermentation of wine. Organoleptic threshold value of isobutyl acetate has been evaluated in Norwegian all-malt pilsener beer. Engineered biosynthesis of isobutyl acetate in Escherichia coli directly from glucose has been reported.

애플리케이션

Isobutyl acetate is suitable ester aroma compound used in the estimation of esters which contribute to the fruity aroma in sweet wines.
