Lipid oxidation in fishes: action mechanism and prevention

Fabiola Helena dos Santos Fogaça, Léa Silvia Sant'Ana


Aquaculture produces food with high nutritive value, however its environmental conditions and management increase the stress reaction of fishes, prejudicing the quality of their products. The lipid oxidation is one of the main causes of the fishery deterioration, due the high unsaturated value of fatty acid of aquatic organisms. This review describes lipid oxidation mechanisms, their analysis methodology and some preventive ways, emphasizing the antioxidants effects of vitamin E utilization in fish’s diet.
