Isoamyl butyrate Usage And Synthesis
  • DescriptionIsoamyl 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.

  • DescriptionIsoamyl 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.

  • UsesIsoamyl 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.
  • DefinitionChEBI: The butanoate ester of isoamylol.
  • PreparationUsually prepared by esterification of commercial isoamyl alcohols with butyric acid by heating in the presence of Twitchell’s reagent; or by fermentation from butyric acid and isoamyl alcohol
  • Taste threshold valuesTaste characteristics at 10 ppm: ripe fruity, fatty, banana, apple, melon and fermented whiskey
