Research progress on active peptides in marine fish

Abstract

With the deepening research on marine resources, active peptides from marine fish have gradually become a hot spot. This review based on the background of the important value and broad application prospect of active peptides in marine fish. Various preparation methods for active peptides from marine fish, such as enzymolysis, extraction, microbial fermentation, and enzymatic hydrolysis, are described in detail. The antioxidant, antibacterial, anti-blood pressure, immunomodulatory, anti-skin photoaging, and anti-fatigue functions and the corresponding mechanisms of action of the active peptides of marine fishes are discussed in depth. The active peptides of marine fish are further proposed to strengthen the in-depth investigation of the mechanism of action and optimise the preparation process in future research, as well as the application in functional food. It is hoped that more ideas can be provided for the safe, effective and compliant application of marine fish active peptides in promoting human health food.
