With rising living standards, food additives are widely adopted in modern food processing, featuring diverse types and versatile functions. When applied within approved usage scopes and dosage limits, food additives help deliver better food quality. Sodium pyrophosphate (TSPP) can be found on the ingredient list of many processed foods.

　　Food grade sodium pyrophosphate is a water-soluble white powder. It serves as a stabilizer and buffering agent in food manufacturing. It is commonly added to soy sauce and fruit juice to brighten and stabilize their colour.

　　Food grade TSPP can chelate metal ions to improve finished food quality. It also works as a melting salt and emulsifier for cheese. It releases calcium ions from calcium caseinate in cheese, increases casein viscosity and produces soft, stretchable cheese. For soy sauce and bean paste, the recommended dosage ranges from 0.005% to 0.3%, which effectively prevents browning and optimizes colour performance.

　　Sodium pyrophosphate has two main grades: industrial grade and food grade. Only food-grade sodium pyrophosphate with valid food additive production qualification can be used for food processing.

　　Chongqing Chuandong Chemical Group supplies qualified food grade sodium pyrophosphate (TSPP) complying with food additive regulations.
