Antioxidants from Crustaceans: A Panacea for Lipid Oxidation in Marine-Based Foods
Oladipupo Odunayo Olatunde, Soottawat Benjakul
Abstract
Lipid oxidation is an important cause of quality deterioration in marine-based foods (MBFs) because of their high contents of poly- and mono- unsaturated fatty acids. Synthetic antioxidants (SAs) have been used for retarding lipid oxidation. However, SAs have been associated with health risks. Therefore, natural antioxidants from animal origin, particularly marine animal processing by-products have become a promising alternative. Crustaceans can serve as an excellent source of valuable bioactive compounds. Information on antioxidants from crustaceans, such as bioactive peptides, chitin derivatives, and carotenoids is revisited. The applications of these antioxidants in impeding lipid oxidation in MBFs are also discussed.
