Chemical Properties

clear colorless to pale yellow liquid

Chemical Properties

2-Dodecenal has a powerful, fatty, citrus-like odor at low levels and a mandarin taste.

Occurrence

Reported found in orange peel oil, kumquat peel oil, milk (0.0006 ppm), grilled and roasted beef, cured pork, roasted peanut (0.02 to 0.11 ppm), coriander leaf and unprocessed rice. Its presence has also been reported in the essential oils of Eryngium facidum and Achasma walang Val.

Uses

Trans-2-Dodecenal is a component of essential oils from Cymbocarpum anethoides and a volatile compound of virgin rapeseed oil.

Definition

ChEBI: (E)-dodec-2-enal is a trans-2,3-unsaturated fatty aldehyde that is (E)-dodec-2-ene in which the allylic methyl group has been oxidised to the corresponding aldehyde. It has a role as an anthelminthic drug, a plant metabolite and an antibacterial agent. It is a trans-2,3-unsaturated fatty aldehyde and a long-chain fatty aldehyde. It derives from a hydride of an (E)-2-dodecene.

Preparation

By condensation of acetaldehyde with decanal; also from α-bromolauric acid by way of the ethyl ester and alcohol.

Aroma threshold values

Detection: 1.4 ppb; aroma characteristics at 0.1% in neobee oil: fatty, waxy, metallic, fatty tallow, greasy, meaty, green vegetative cucumber with chicken and cilantro notes.

Taste threshold values

Taste characteristics at 0.1 ppm: strong aldehydic, soapy, vegetative green, celery and cucumber-like, banana musty, chicken fatty and brothy.

Safety Profile

A severe skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes
