Abstract: Acidic electrolyzed water (AEW) is a new green and promising technology for food preservation with the advantages of high safety, broad-spectrum antimicrobial activity, efficient preservation and low cost. AEW is characterized by low pH, high redox potential and a considerable concentration of available chlorine. AEW represents a new alternative to the traditional preservation method for aquatic products, and has been successfully used in the sterilization and inactivation of enzymes in aquatic products. In addition, AEW can work synergistically with other sterilization technologies yielding improved preservation effect. This article summarizes the mechanism of action of AEW as a preservative, and reviews the latest advances in its application in aquatic products. Finally, we conclude with a discussion of future prospects, with a view to providing a theoretical guidance for the application of AEW in the preservation of aquatic products.
