Technical Document

Sodium Acid Pyrophosphate Sodium acid pyrophosphate is an inorganic phosphate salt used mainly as a leavening acid, sequestrant, and pH regulator in food systems. It is valued for its controlled reaction rate with sodium bicarbonate, which allows precise management of gas release, texture, and volume in baked and processed foods, as well as for its ability to bind metal ions and influence protein functionality.
