Isoamyl butyrate Chemical Properties,Usage,Production
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
Isoamyl butyrate has a fruity, apricot, pineapple, banana, strong, characteristic odor and a sweet, corresponding taste
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
Isoamyl butyrate is a clear colorless mobile liquid. B.P. 1795 C. Sp.Gr. 0.87. Insoluble in water, soluble in alcohol, essential oils, perfume and flavor materials. Powerful and diffusive fruity, sweet Apricot-Banana-Pineapple-like odor, somewhat sharper than that of the iso-Amyl-iso-buty rate. Sweet and fruity taste, not very powerful, yet stronger than the acetate.
Occurrence
Reported found in the oil of Eucalyptus macarthuri and in coconut oil. Also reported found in apple, apricot, banana, kumquat peel oil, guava, grapes, melon, strawberry, tomato, cheeses, beer, cognac, rum, Scotch whiskey, cider, grape wines, port, honey, yellow passion fruit, plum, mango, plum wine, cashew apple, cherimoya, bilberry wine, mountain papaya, Roman chamomile, mastic gum leaf and fruit oil.
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.
Uses
manufacture of artficial rum and fruit essences. Extensively used in flavor compositions. This ester may constitute a large percentage of many fruit flavors, such as: imitation Apricot, Banana, Cherry, Peach, Strawberry, "Tutti- -frutti", etc. and in Butter, Butterscotch, Chocolate, etc. Concentration in finished product may be 80 ppm in candy, and up to 550 ppm in chewing gum. Occasionally used to impart "lift" to perfumes and to modify "creamy" notes with Amyl phenylacetate, Vanillin, etc.
Definition
