trans,trans-2,4-Decadien-1-al Usage And Synthesis
Chemical Properties clear yellow liquid
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 bee f, fish, potato chips, roasted peanut, buckwheat and wheat bread crumb.
Preparation By autooxidation of methyl (trans, trans)-linolate hydroperoxide.
