Benzyl isobutyrate Usage And Synthesis

Chemical Properties

Benzyl isobutyrate has a fresh, floral, somewhat jasmine-like, fruity odor and sweet, strawberry-like taste.

Occurrence

Reported found in mint, spearmint, beer, cherimoya (Annona cherimolia Mill.) and Passiflora edulis hybrid juice.

Definition

ChEBI: Phenylmethyl 2-methylpropanoate is a carboxylic ester. It is functionally related to a benzyl alcohol.

Preparation

May be prepared from benzyl alcohol and isobutyric acid, by the action of aluminum ethylate on a mixture of benzyl and butyric aldehydes.

Taste threshold values

Taste characteristics at 10 ppm: fruity and sweet with ripe berry nuances.
