What it is

Ammonium bicarbonate is a chemical compound that is a white powder or crystalline solid. It is produced industrially through a reaction involving ammonia, carbon dioxide, and water. It is a salt of carbonic acid.

Why it's used

Ammonium bicarbonate is used as a leavening agent in baking, particularly in cookies and crackers. When heated, it breaks down into ammonia, carbon dioxide, and water, causing baked goods to rise and become lighter. It is often used when a crisp texture is desired.

Health notes

In the United States, ammonium bicarbonate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved as a food additive in the European Union. International bodies like JECFA have evaluated it. At typical levels found in food, it is not associated with adverse health effects.
