1. What is Sodium Acid Pyrophosphate (SAPP)?

　　Sodium Acid Pyrophosphate, commonly abbreviated as SAPP, is also named disodium dihydrogen pyrophosphate. With CAS number 7758-16-9 and additive code E450(i) / INS 450(i), it is a widely used functional food-grade phosphate.

　　Produced by Chuandong Chemical, this product appears as white, odorless and free-flowing crystalline powder. It dissolves easily in water while being insoluble in ethanol. Thanks to its excellent leavening effect, pH buffering capacity and metal chelating property, SAPP is an indispensable ingredient for modern food production worldwide.

　　2. What are the Main Functions of SAPP?

　　Our food grade Sodium Acid Pyrophosphate features stable performance and multiple functions to meet various food processing needs:

　　Leavening Agent: Reacts steadily with sodium bicarbonate to release carbon dioxide, creating fluffy texture for baked goods and frozen dough.

　　pH Stabilizer & Buffer: Maintains stable pH value of food systems, prevents deterioration and extends shelf life.

　　Metal Ion Chelator: Blocks adverse reactions caused by metal ions, avoiding discoloration and rancidity of finished products.

　　Water Retention Agent: Improves tenderness and water holding capacity of meat and seafood, reducing juice loss during cooking.

　　High Safety Level: Strict control over heavy metals and impurities, fully compliant with global food safety regulations.
