Is ammonium bicarbonate e503ii vegan?

Ammonium bicarbonate, designated by the food additive code E503ii, is a chemical leavening agent commonly known as ammonium hydrogen carbonate or baking ammonia. It is manufactured industrially by combining carbon dioxide with aqueous ammonia, resulting in a white crystalline powder that decomposes into ammonia, carbon dioxide, and water when heated.

This additive is widely used in commercial baking, particularly in dry, crisp baked goods like crackers, cookies, wafers, and traditional flat pastries. Because it releases gases that escape completely during the baking of thin foods, it provides a light and airy texture without leaving a chemical aftertaste.

Ammonium bicarbonate E503ii is classified as vegan because it is an inorganic, synthetic compound produced entirely from mineral and chemical feedstocks. No animal tissues, animal byproducts, or animal-derived processing aids are utilized at any stage of its production.
