Description

General description

trans,trans-2,4-Decadienal is one of the main volatile flavor constituents of rice, tomato, cold-pressed orange and tangerine oils. It has also been identified in frying oils and fumes since it is formed as a by-product when lipids in edible oils undergo peroxidation on heating.

Application

• Multispectral and Molecular Dynamics Study on the Impact of trans,trans-2,4-Decadienal and 4-hydroxy-2-nonenal on Myoglobin Redox Stability.: The study examines the effects of lipid oxidation products on protein stability, with significant implications for understanding oxidative stress and its impact on muscle foods (Qi et al., 2024).
