What it is

E503ii is ammonium carbonate, a chemical compound made from ammonia and carbon dioxide. It is a white crystalline powder that readily dissolves in water. It is produced industrially through a reaction between ammonia and carbon dioxide.

Why it's used

Ammonium carbonate is used as a leavening agent in baking, particularly in cookies and crackers. It helps baked goods rise and become lighter by producing carbon dioxide gas when heated. It is often found in products like cookies, cakes, and biscuits.

Health notes

In the US, ammonium carbonate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is considered safe when consumed in amounts typically found in food. International bodies like JECFA have evaluated ammonium carbonate, but did not set a specific numerical acceptable daily intake.

Allergen info

Ammonium carbonate is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
