Description and Uses
Isoamyl butyrate has a strong, characteristic, fruity (pear-like) odor and a sweet, corresponding taste. Usually prepared by esterification of commercial isoamyl alcohols with butyric acid by heating in the presence of TwitchelFs reagent; or by fermentation from butyric acid and isoamyl alcohol.
Isoamyl Butyrate is a synthetic flavoring agent that is a stable, col- orless liquid of strong fruity odor. it is usually prepared by esterifica- tion of isoamyl alcohols with butyric acid. it is soluble in most fixed oils and mineral oil and is insoluble in glycerin and propylene gly- col. storage should be in glass, tin, or resin-lined containers. it is used in fruit flavors such as pineapple, raspberry, and strawberry and has application in dessert gels, puddings, and baked goods at 50–60 ppm.
