Is bicarbonate de ammonium vegan?

Bicarbonate de ammonium, also known as ammonium bicarbonate, is a white, crystalline powder commonly used in baking as a leavening agent. Unlike other leavening agents, such as baking soda and baking powder, bicarbonate de ammonium releases gas at a much slower rate, resulting in a more controlled rise in baked goods. It has a distinct ammonia smell when heated, which dissipates during baking. Bicarbonate de ammonium is often used in traditional European baked goods, such as German Lebkuchen and Swedish Pepparkakor cookies, due to its unique properties.
