Sodium tripolyphosphate (STPP) is a water retention agent. This is a much-needed property for processed meat products because this chemical reacts well with the proteins and globulins in the meat

1.Meat and Seafood: STPP is commonly used in the processing of meat and seafood products. It helps to improve the moisture retention and texture of these products, particularly during freezing and thawing processes. In seafood, STPP is often used to prevent freezer burn and maintain the freshness of products like shrimp, scallops, and fish fillets.
2.Processed Foods: STPP is used in many processed foods, such as canned soups, sauces, and ready-to-eat meals. It serves as a preservative, helping to extend the shelf life of these products by inhibiting microbial growth and enzymatic reactions that can cause spoilage.
3.Cheese and Dairy Products: In cheese manufacturing, STPP can be used as a sequestrant, helping to prevent the formation of calcium phosphate crystals that can affect the texture and appearance of cheese. It may also be used in dairy products like evaporated milk and condensed milk to stabilize emulsions and improve texture.
4.Baked Goods: While less common in baked goods compared to other food categories, STPP may be used in some formulations to improve dough stability, increase water retention, and enhance the volume and texture of baked products.
5.Beverages: STPP is not commonly used in beverages, but it may be found in some powdered drink mixes and fruit juices as a buffering agent to maintain pH stability and prevent flavor degradation.
6.Other Foods: STPP may also be found in various other food products where its functions as a preservative, emulsifier, or texture modifier are beneficial, such as processed meats, frozen desserts, and instant noodles.
