Sodium Acid Pyrophosphate, SAPP

Sodium Acid Pyrophosphate, SAPP is an inorganic compound consisting of sodium cations and pyrophosphate anion. It is a white, water-soluble that serves as a buffering and chelating agent, with many applications in the food industry. When crystallised from water, it forms hexahydrate, but it dehydrates above room temperature. Sodium Acid Pyrophosphate, SAPP is a polyvalent anion with a high affinity for polyvalent cations.

Sodium Acid Pyrophosphate, SAPP is a popular leavening agent found in baking powders. It combines with sodium bicarbonate to release carbon dioxide. It is available in a variety of grades that effect the speed of its action. Because the resulting phosphate residue has an off-taste, Sodium Acid Pyrophosphate, SAPP is usually used in very sweet cakes which mask the taste.

Sodium Acid Pyrophosphate, SAPP is designated in the USA as generally recognized as safe for food use. It is used in canned seafood to maintain color and reduce purge during retorting. Retorting achieves microbial stability with heat. It is an acid source for reaction with baking soda to leaven baked goods. In baking powdeer, it is often labeled as food additive E450. In cured meats, it speeds the conversion of sodium nitrite to nitrite by forming the nitrous acid intermediate, and can improve water-holding capacity. 

In leather treatment, Sodium Acid Pyrophosphate, SAPP can be used to remove iron stains on hides during processing. It can be used with sulfamic acid in some dairy applications for cleaning, especially to remove soapstone. When added to scalding water, it facilitates removal of hair and scurf in hog slaughter and feathers and scurf in poultry slaughter. 

Sodium Acid Pyrophosphate, SAPP in petroleum production, it can be used as a dispersant in oil well drilling muds. 

Sodium Acid Pyrophosphate, SAPP can also be found in frozen hash browns and other potato products, where it is used to keep the color of the potatoes from darkening.
