(2E,4E)-deca-2,4-dienal is a polyunsaturated fatty aldehyde derived from decanal that has undergone formal dehydrogenation, resulting in the introduction of trans-double bonds at the 2-3 and 4-5 positions. It is a product of lipid peroxidation in cell membranes and is also found in cooking oil fumes. This compound serves various roles, including being a nematicide (used to kill plant-parasitic nematodes) and an apoptosis inducer. 2,4-Decadienal is a natural product found in organisms such as Vaccinium vitis-idaea and Streptomyces. Additionally, trans,trans-2,4-decadienal is a metabolite found in or produced by Saccharomyces cerevisiae. (E,E)-2,4-Decadienal is an aromatic substance present in various food items, including butter, cooked beef, fish, potato chips, roasted peanuts, buckwheat, and wheat bread crumbs. In its isolated form, it has a deep fat flavor, reminiscent of a chicken aroma (at 10 ppm concentration). At lower concentrations, it exhibits the odor of citrus, resembling notes of orange or grapefruit. It is worth noting that (E,E)-2,4-decadienal has raised concerns about its potential carcinogenicity. While it has been used as an aroma in the European Union, there are restrictions on its use until the required data regarding its safety have been submitted. This compound has diverse sensory properties and is found in a range of food products, contributing to their characteristic aromas and flavors, but its safety for consumption is subject to regulatory scrutiny.
