Sodium tripolyphosphate is a common ingredient added to fish (e.g. salmon) before frozen and its primary purpose is to reduce the amount of thaw water (or maintain water) and make seafood look firmer and smoother. 
Sodium tripolyphosphate may also find it in other frozen seafood, such as scallops, shrimp, and lobster.
The taste, odor, texture, and juiciness are important properties of seafood but most seafood is easily damaged caused by ice crystals and the protein denaturation during the freezing storage. 

Sodium tripolyphosphateis the protein in fish meat that determines the water retention performance. 
Polyphosphate is a widely used water-retaining agent for seafood to prevent protein denaturation during freezing. 
In the production of frozen fish fillets, the fish fillets are soaked in a solution of sodium tripolyphosphate with a certain concentration before freezing.
The level of water retention performance is closely related to the quality of fish products such as texture, tenderness, sliceability, elasticity, and taste. 
If without sodium tripolyphosphate, when thawed, most seafood is prone to lose weight (water) and generate a darker appearance and as well make the body fragile.
