Based on the analysis of the mechanism of freezing and dehydration of aquatic products, the relevant literatures on the development and application of salt water-retaining agents, sugar water-retaining agents, and protein gel water-retaining agents were combed. It was pointed out that excessive addition would worsen the flavor of aquatic products, although salt water-retaining agents had better performance. Sugar-based water-retaining agents and protein gel-based water-retaining agents were natural, green and safe, but the water-retaining properties alone were weak and costly. In view of this, through the use of natural ingredients such as polysaccharides and oligosaccharides, the production cost of sugar water-retaining agents was reduced, or sugar water-retaining agents and protein gel water-retaining agents were used as the main raw materials to mix with phosphorus-free salts. The synergistic effect of the composite water-retaining agent to enhance the water-retaining will effect and reduce the application cost can become future research directions. [ABSTRACT FROM AUTHOR]
