(E,E)-2,4-Decadienal is an aromatic substance found in butter, cooked beef, fish, potato chips, roasted peanut,[2] buckwheat[3] and wheat bread crumb.[4] In an isolated state, it smells of deep fat flavor, characteristic of chicken aroma (at 10ppm). At lower concentration, it has the odor of citrus, orange or grapefruit. It might be carcinogenic.[5] It has been used as aroma in the EU, but use restrictions apply until the required data have been submitted.[6]
