Polyphenols are secondary metabolites produced by plants when they are under stress and initiate self-defense mechanisms. Because of their large number of hydroxyl groups, they have many biological activities such as anti-oxidation, anti-bacterial and anti–tumor. It has become a research hotspot. The good antioxidant and bacteriostatic effects of polyphenols make it a highly promising biological preservative. In this paper, polyphenols were classified according to their sources, and its composition and properties as well as the biological activities related to preservation were briefly described. And focus on the research progress and development trend in the field of aquatic product preservation in order to provide reference for further expanding the application of polyphenols in the field of biological preservatives.
