STPP (sodium tripolyphosphate, with the chemical formula Na₅P₃O₁₀) is a versatile inorganic compound with functions such as chelation, dispersion, emulsification, and buffering. It is widely used in various fields.
Application
Food Industry
-
Moisture Retention Agent: STPP can enhance the water-holding capacity of meat and fish products, keeping them moist and tender during processing and storage. For example, in the processing of frozen shrimp, STPP acts as a moisture retention agent by binding with myofibrillar proteins in the shrimp meat to form a stable structure. This helps reduce the damage to cell membranes caused by ice crystals during freezing.
-
Quality Improver: It can increase the tenderness and texture of meat, improving the overall flavor and eating experience of food.
-
pH Regulator: STPP can also regulate the pH of food, keeping it stable and thereby extending the shelf life of food products.
-
Metal Chelating Agent: It can chelate metal ions in food, preventing them from participating in undesirable reactions.
Ceramic Industry
-
Dispersant: In ceramic manufacturing, STPP is mainly used as a dispersant. It can prevent solid particles in ceramic slurries from aggregating, improving the fluidity and stability of the slurry.
-
Grinding Aid: It can improve ball milling efficiency, reduce energy consumption, and shorten ball milling time.
-
Deflocculant: STPP can improve the rheological properties of ceramic slurries, enhancing the forming properties of the ceramic body.
Other Applications
-
Paper Industry: STPP is used as an anti-grease agent in the paper industry.
-
Building Materials Industry: STPP is used as a cement additive to improve the fluidity of cement and delay its setting time.
-
Leather Industry: STPP also has applications in the leather industry.
