Isoamyl butyrate Usage And Synthesis


Description

Isoamyl Butyrate is a chemical ester of butyrate. It is a kind of flavoring agent that widely used in the preparation of a variety of fruit juice flavor, such as apricots, bananas, pears, apples and other flavor. It is high-demand flavor and fragrance compounds widely used in the food, beverage, cosmetic, and pharmaceutical industries. It is also a kind of solvent for extracting natural spices and the solvent of acetate fiber. Its synthesis can be mediated by the lipase (from various sources) catalyzed esterfication of isoamyl alcohol and butyrate.

Description

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.

Chemical Properties

Chemical Properties

Isoamyl Butyrate is a liquid with strongly fruity odor that occurs, for example, in banana. It is used mainly in fruit flavors.

Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

manufacture of artficial rum and fruit essences.

Uses

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.
