TRANS,TRANS-2,4-DECADIENAL Chemical Properties,Usage,Production

Chemical Properties 2-trans, 4-trans-Decadienal has a powerful, oily, chicken fat odor and a sweet, orange-like odor at high concentration. It has a grapefruit- or orange-like taste on dilution.
Occurrence Reported as occurring in peanut oil and, as a volatile component, in fried potatoes, the trans, trans- form is reported found among the volatile flavor components of potato chips and tomato. Also found in citrus peel oils, orange juice, tangerine juice, guava fruit, strawberry fruit, cabbage, carrot, raw potato, bell pepper, butter, cooked chicken, beer, rum, tea, peanut oil, popcorn, potato chips, corn tortilla, oatmeal, Brazil nut, roasted almonds, roasted peanuts and pecans, soybeans, cassava, caviar, cooked beef, lamb, mutton, and fish.
Uses trans,trans-2,4-Decadienal is an aldehyde with a fat flavor aroma characteristic of chicken but has a citrus odor at lower concentrations. trans,trans-2,4-Decadienal can be found in butter, cooked beef, fish, potato chips, roasted peanut, buckwheat and wheat bread crumb.
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.
Preparation By autooxidation of methyl (trans, trans)-linolate hydroperoxide.
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
