| General description: | 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. |
