용도
개요
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.
출처
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.
용도
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.
일반 설명
