What it is

Calcium acid phosphate is a chemical compound made from calcium, phosphorus, and oxygen. It is typically produced by reacting calcium carbonate or calcium hydroxide with phosphoric acid. It is a white powder that is odorless and tasteless.

Why it's used

Manufacturers add calcium acid phosphate to foods as a leavening agent, helping baked goods rise and become fluffy. It can also act as a dough conditioner, improving texture and consistency. It is commonly found in baked goods like cookies, muffins, and pastries, as well as in some flour mixes.

Health notes

In the U.S., calcium acid phosphate is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. It is a source of calcium and phosphorus, which are essential minerals for bone health. International bodies like JECFA have evaluated it. Evidence does not suggest adverse health effects at typical dietary intake levels.

Allergen info

Calcium acid phosphate is not derived from any of the FDA's major allergens and does not contain gluten.
