Ammonium bicarbonate is an inorganic compound widely used in the food industry as a leavening agent. It decomposes into carbon dioxide, ammonia, and water upon heating. This makes it ideal for flat baked goods such as crackers and cookies.
Unlike baking soda, it leaves no residual sodium in the finished product. It is valued for producing light, crispy textures in baked goods. Ammonium bicarbonate is also used in certain confectionery and snack food manufacturing processes.
