Chemical Properties

trans-2-Nonen-1-ol is an unsaturated nonaromatic alcohol

Chemical Properties

White liquid; fatty, violet odor.Insoluble in water.

Occurrence

Reported found as a volatile component in Cucurbitaceae (cucumber, squash, pumpkin), in chicken fat, cognac, kelp, prickly pear, malt, nectarine and asparagus.

Uses

Food additive.

Definition

ChEBI: (E)-non-2-en-1-ol is a medium-chain primary fatty alcohol that is (E)-non-2-ene carrying a hydroxy group at position 1. It has a role as a flavouring agent, a plant metabolite and a pheromone. It is a medium-chain primary fatty alcohol, a primary allylic alcohol and a volatile organic compound.

Preparation

By hydrolysis of the corresponding acetate; the acetate is prepared from 1-bromo-2-nonene and acetic anhydride in acetic acid solution

Aroma threshold values

Detection: 130 ppb

Taste threshold values

aste characteristics at 10 ppm: green, fatty, melon with a chicken fat and lard nuance
