Freshness Preserved By Sodium Acid Pyrophosphate

Sodium acid pyrophosphate (SAPP) is a white, crystalline powder. It is a salt made from phosphoric acid, which occurs naturally in the body and in foods like meat and dairy. SAPP is produced industrially by heating sodium phosphate.

SAPP is used as a leavening agent in baked goods, helping them rise and become fluffy. It also acts as a preservative, preventing browning in processed potatoes and seafood. It is frequently found in potato products, baked goods, and some meats.

In the U.S., SAPP is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. 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. Some studies have looked at the effects of high phosphate intake on bone health, but evidence is mixed and not specific to SAPP.
