Uses

Sodium Pyrophosphate is a leavening agent, preservative, sequestrant, and buffer which is mildly acidic with a ph of 4.1. It is moderately soluble in water, with a solubility of 15 g in 100 ml at 25°c. It is used in doughnuts and biscuits for its variable gas release rate during the mixing, bench action, and baking process. It is used in baking powder as a leavening agent. It is used in canned fish products to reduce the level of undesired struvite crystals (magnesium ammonium phosphate hexahydrate) by complexing the magnesium. It is used to sequester metals in processed potatoes. It is also termed sapp, sodium acid pyrophosphate, acid sodium pyrophosphate, disodium diphosphate, and disodium dihydrogen pyrophosphate.
