The harm of lipid oxidation on aquatic products during the freezing process, the endogenous and exogenous pro-oxidation factors that led to lipid oxidationwere reviewed. It summarized the current methods of delaying lipid oxidation, such as adding antioxidants, improving packaging and new technology, and pointed out that the technology which can not only control the lipid oxidation of aquatic products in the process of frozen storage but also realize industrial promotion is an urgent problem to be solved.
