Hazard Information | Back Directory | [Chemical Properties]
clear colorless to yellowish liquid | [Occurrence]
Reported found in Bartlett pears, apple, grape, durian (Durio zibethinus), pear brandy, quince and spineless
monkey orange (Strychnos madagasc). | [Uses]
Potential applications include the profile enhancement of guava, melon, pear, apple, banana, kiwi, grape, golden delicious apple, fruit cocktail juices, fruit nectar, mamey and other tropical backgrounds. | [Definition]
ChEBI: Ethyl (2E,4Z)-deca-2,4-dienoate is a fatty acid ethyl ester resulting from the formal condensation of the carboxy group of (2E,4E)-deca-2,4-dienoic acid with the hydroxy group of ethanol. It has a role as a plant metabolite, a flavouring agent, a fragrance and a kairomone. It is functionally related to a (2E,4E)-deca-2,4-dienoic acid. | [Aroma threshold values]
Detection: 100 ppb. Aroma characteristics at 1.0%: sweet ripe pear, creamy and slightly fatty with fruity,
green, waxy apple, fleshy nuances | [Taste threshold values]
