What is trans-2-Hexenyl acetate?

Description

trans-2-Hexen-l-yl acetate has a pleasant, fruity odor and corresponding taste. This substance may be synthesized by heating at the boil l-bromohexen-2 -ol with sodium acetate and acetic acid.

Chemical properties

clear colorless to slightly yellow liquid

Chemical properties

(E)-2-Hexenyl Acetate occurs in many fruits and in some essential oils, for example, peppermint. It is a fresh, fruity, slightly green-smelling liquid and is used in fruit flavors.

Chemical properties

2-Hexen-1-yl acetate has a pleasant, fruity odor and corresponding taste.

Occurrence

Reported found in Fragaria vesca and other fruits; only the trans-form is known. Also reported in apple, apple juice, apricot, bilberry, guava, peach, blackberry, strawberry fruit and jam, tomato, corn mint oil, spearmint oil, white and red wine, tea, plum, plumcot, mushroom, starfruit, mango, banana and passion fruit.

Preparation

By heating at the boil, 1-bromohexen-2-ol with sodium acetate and acetic acid.

Definition

ChEBI: (E)-hex-2-enyl acetate is an acetate ester resulting from the formal condensation of the hydroxy group of (E)-hex-2-en-1-ol with the carboxy group of acetic acid. It has a role as a plant metabolite and a flavouring agent. It is an acetate ester and an olefinic compound. It is functionally related to an (E)-hex-2-en-1-ol.

Taste threshold values

Taste characteristics at 10 ppm: sweet, green, fresh and fruity with a waxy apple background.
