Abstract:Marine fish are rich in nutrients and high in water content, and are prone to spoilage in the cold chain logistics. Therefore, understanding the spoilage mechanism of marine fish in cold chain logistics, and then carrying out targeted preservation of marine fish products, greatly improve the quality of marine fish products in cold chain. This review discusses the mechanisms of autolytic spoilage, oxidative spoilage and microbial spoilage in the cold chain logistics of marine fish, and focuses on the research progress of the preservation technology for controlling microbial spoilage. The surface microbial of marine fish can be effectively reduced by the ozone water, electrolyzed water, low temperature plasma, irradiation sterilization, high hydrostatic pressure, photodynamic sterilization technology and other bacteria-reducing technologies. Then the low temperature control, modified atmosphere packaging and active packaging technologies are used to control the microbial growth, protein and lipid oxidation of marine fish in the cold chain logistics, which could maintain the freshness quality of marine fish. These findings can provide a reference for the further development of preservation technology applied to the marine fish in the cold chain logistics.
