What are the applications of Application
Decadienal is a lipid peroxidation product from cell membranes
Preparation
By autooxidation of methyl (trans, trans)-linolate hydroperoxide.
Definition
ChEBI: (2E,4E)-deca-2,4-dienal is a polyunsaturated fatty aldehyde that is decanal which has undergone formal dehydrogenation to introduce trans- double bonds at the 2-3 and 4-5 positions. A product of lipid peroxidation in cell membranes and a component of cooking oil fumes. It has a role as a nematicide and an apoptosis inducer.
Aroma threshold values
Detection: 0.07 to 10 ppb. Aroma characteristics at 0.1%, rich fatty, aldehydic, green melon, chicken fat, oily and creamy with chicken stock and chicken meat nuances.
Taste threshold values
Taste characteristics at 2 ppm: rich oily fatty, aldehydic, green, chicken meat with tropical fruit and cilantro nuances
