Sodium Tripolyphosphate (STPP) is a white crystalline powder that is highly soluble in water, with an alkaline solution. It exhibits strong chelating properties, binding with metal ions to prevent precipitation, and possesses excellent emulsifying and dispersing capabilities. STPP is chemically stable and maintains its functional properties even at high temperatures.
Applications: In the food industry, STPP is widely used in the processing of meat, seafood, and dairy products to enhance water retention, improve texture, and extend shelf life. In detergents, it serves as a water softener and cleaning aid, effectively boosting cleaning performance. Additionally, STPP is utilized in industrial water treatment, ceramic production, and the textile industry as a dispersant, stabilizer, or pH regulator. Its versatility and efficiency make it a vital component in various industries.
