What it is

Sodium acid pyrophosphate (SAPP) is a salt made from sodium and pyrophosphoric acid. It is a white powder that dissolves in water. It is often produced by heating sodium phosphate.

Why it's used

SAPP is used as a leavening agent in baked goods like cakes and donuts, helping them rise. It also acts as a stabilizer and emulsifier in processed foods such as potato products and seafood, preventing undesirable changes in color and texture.

Health notes

SAPP is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of phosphorus, an essential mineral. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated SAPP and established an acceptable daily intake. High phosphorus intake from all sources can be a concern for individuals with kidney disease.
