Sodium Tripolyphosphate (STPP) is a vital inorganic phosphate compound widely used in industrial production and food processing. Its molecular structure contains three phosphate units (PO₄³⁻) linked by oxygen bridges to form a linear chain. This unique structure provides multiple chelation-active sites. Consequently, STPP possesses excellent complexing, dispersing, emulsifying, and water-retention properties, making it one of the most produced and used polyphosphates globally

Among the family of phosphate products, Sodium Tripolyphosphate (STPP) is a significant multifunctional inorganic salt that plays a key...
