What it is

Sodium acid pyrophosphate is a white, crystalline powder. It is a salt made from phosphoric acid, a common chemical compound. It is often used in food processing as a leavening agent.

Why it's used

In foods, it helps baked goods rise by reacting with baking soda to produce carbon dioxide gas. It is also used to prevent discoloration in processed potatoes and seafood, and to help maintain texture in some dairy products.

Health notes

Sodium acid pyrophosphate is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of phosphorus, an essential mineral. JECFA has evaluated it and set an acceptable daily intake. While it contains sodium, its contribution to overall sodium intake from food is usually small.

Allergen info

Not a major allergen. It does not contain gluten.
