What is Sodium Acid Pyrophosphate?
Sodium Acid Pyrophosphate is a food-grade and synthetic phosphoric salt that appears as a white, odorless powder. It serves multiple functions, including acting as a leavening agent for dough, a preservative, and a buffering agent. Other names for Sodium Acid Pyrophosphate include disodium dihydrogen pyrophosphate, SAPP, disodium diphosphate, sodium pyrophosphate, and pyrophosphate.

Uses of Sodium Acid Pyrophosphate
Sodium Acid Pyrophosphate is widely used in various applications, particularly in the food industry, due to its unique properties. Here are some of its key uses:
Leavening Agent: When combined with sodium bicarbonate, it releases carbon dioxide gas, which helps in leavening dough, making it fluffy or puffed. This gas increases the volume and sponginess of baked goods such as bread, biscuits, cookies, donuts, and other flour-based products.
Enhancing Dough Performance: Besides sodium acid pyrophosphate, other agents like tartaric acid, cream of tartar, monocalcium phosphate, dicalcium phosphate, and sodium aluminum phosphate also influence dough rising.
Baking Powder Production: Sodium acid pyrophosphate is extensively used in producing baking powder and dough conditioners, particularly in bread, cakes, cookies, and to some extent, biscuits and wafers.
Seafood Preservation: In seafood products, it prevents the formation of struvite crystals.
Meat and Protein Products: It is used to maintain color stability and increase shelf life in meat and protein products.
Canned Foods: In canned foods, it reduces unwanted crystals (magnesium ammonium hexahydrate) by forming complexes with magnesium.
Dairy Industry: It serves as an emulsifying agent in dairy products.
Classification: Sodium acid pyrophosphate is categorized into three groups based on its release rate of carbon dioxide (CO2): fast, medium, and slow pyrophosphate. Consumers select the appropriate type according to their product formulation needs.
Import Sources: In our country, the majority of sodium acid pyrophosphate imports come from China, although it is sometimes sourced from Germany and Thailand as well.
