What it is

Sodium acid pyrophosphate is a white, crystalline powder. It is a salt made from phosphoric acid and sodium. It is often produced industrially by heating sodium phosphate.

Why it's used

This ingredient acts as a leavening agent, helping baked goods rise. It also helps maintain color and texture in processed meats and seafood. It is commonly found in baked goods like cookies, cakes, and pastries, as well as in some processed potato products.

Health notes

Sodium acid pyrophosphate is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is used in small amounts and is not known to cause harm at typical consumption levels. International bodies like JECFA have evaluated it. Some research suggests high phosphate intake from all sources could be a concern for people with kidney problems, but this is not specific to sodium acid pyrophosphate.
