| Hazard Information | Back Directory | [Chemical Properties]
2-Dodecenal has a powerful, fatty, citrus-like odor at low levels and a mandarin taste. | [Chemical Properties]
2-Dodecenal is a colorless liquid with a powerful aldehydic,
mandarin, citrus-like odor. It may be prepared as described earlier, see
2-hexenal,. 2-Dodecenal is used in flavors and fragrances to create orangemandarin-
like citrus notes. | [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: 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. | [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]
