Sodium acid pyrophosphate (SAPP) is a white, water-soluble, inorganic compound widely used as a food additive and industrial ingredient. In the food industry, it serves as a leavening agent in baked goods, a sequestrant to prevent discoloration in potatoes and canned seafood, and a stabilizer in processed meats to retain moisture. Beyond food, it finds applications in detergents, water treatment, and metal surface conditioning due to its dispersing and chelating properties.
