Sodium Acid Pyrophosphate Food Grade also known as SAPP or disodium pyrophosphate is mainly used in the food applications and food processing. Sodium acid pyrophosphate food grade is extensively used in food processing, as in canned seafood, cured meat and potato products, to adjust the pH, maintain color, improve the water-holding capacity and reduce purge during retorting, Additionally, SAPP is a popular leavening agent found in baking powders. It also has industrial applications such as It is used as a buffering agent in labs, as a chelating agent in antimicrobial studies, as a food acidulant, as a peptizing agent for foodstuffs, as a corrosion inhibitor, as an anti-scaling agent, and as a sequestering agent. It is used in electroplating, metal cleaning, and drilling mud.
