At present, aquatic products are mainly stored and sold through ice storage, which has high additional costs. Ordinary low-temperature freezing also has disadvantages such as meat hardening and poor freshness, greatly limiting the circulation and transportation of aquatic products. Fresh aquatic products caught can be soaked in acidic electrolyzed water for sterilization, and then refrigerated with acidic electrolyzed water ice cubes to extend the shelf life of aquatic products as much as possible. In current preservation experiments, fish are often used as research objects. Previous studies have shown that hairtail treated with acidic electrolyzed water significantly reduces the total number of bacteria and prolongs the refrigeration shelf life by 2-3 days compared to the control group. A study was conducted on the preservation of pufferfish using slightly acidic electrolyzed water, and the results showed that the hardness, elasticity, and recovery of pufferfish treated with electrolyzed water were 1.10-1.45 times that of the control group. Under the same refrigeration conditions, the shelf life can be extended by 2 days. By treating carp fillets with alkaline electrolyzed water, acidic electrolyzed water, and 1% essential oil compounds for 15 minutes, it was found that these three combined treatments can effectively reduce the number of microorganisms on the surface of the fillets and inhibit microbial growth; At the 5th day of storage, the volatile basic nitrogen content of carp fillets remained at a low level, and sensory analysis showed that the color, flavor, color, and texture of the treated fillets had almost no changes.
The application of acidic electrolyzed water in the aquaculture industry still needs to be strengthened in domestic research. Existing reports mainly focus on the application of strongly acidic electrolyzed water, while there are few reports on the application of slightly acidic electrolyzed water. In addition, there are almost no reports on the application of sterilization in aquaculture water bodies. Compared with strongly acidic electrolyzed water, slightly acidic electrolyzed water has milder sterilization treatment conditions, less corrosiveness to equipment and operators, almost no residual chlorine, and low operating costs. It can be used in aquaculture and from the source to the consumption process of aquatic products. Therefore, further research and application promotion of slightly acidic electrolyzed water should be strengthened.
