| | 2-Undecenal Usage And Synthesis |
| Chemical Properties | 2-Undecenal has a powerful, fresh aldehydic odor. The commercial product is a mixture of several isomers of undecylenic
aldehyde. This compound exhibits fungistatic activity. | | Occurrence | Reported found among the volatile components in fish products, also formed in the oxidative decomposition of
heated lard; its presence in nature has been reported in cranberry and bilberry, milk, cooked chicken, heated beef and pork, roasted
filberts, roasted peanuts, pecans, coriander seed and leaf, soybean, kiwifruit and potato chips. | | Definition | ChEBI: 2-undecenal is an undecenal in which the C=C bond is located at the 2-3 position. It is an undecenal, a n-alk-2-enal and a volatile organic compound. | | Preparation | By oxidation of 2-undecanol. | | Taste threshold values | Taste characteristics at 15 ppm: waxy, addehydic, green, with a citrus and meaty nuance. |
