Applications of Sodium Tripolyphosphate (STPP)

Improves taste and texture of food, making it more delicate and soft while preventing protein condensation
Acts as water retaining agent and preservative by forming soluble complexes with metal ions in food
Functions as leavening agent in baked goods to increase volume and softness
Serves as coagulant for proteins and starch to improve food structure and stability
Works as metal chelating agent and pH regulator to prevent scale formation and improve food stability

Benefits in Dairy Products

Prevents agglomeration during heating by forming stable complexes with proteins and fats
Enhances water retention to maintain moisture content during storage and transportation
Improves texture and mouthfeel of dairy products
