Ammonium bicarbonate is widely used in the food industry as a leavening agent in baked goods such as cookies, crackers, and flatbreads. It releases carbon dioxide gas when heated, causing dough to rise and create a light, airy texture. In agriculture, it serves as a nitrogen source in fertilizers, promoting plant growth. It is also employed in the production of ceramics and plastics as a foaming agent. Additionally, it finds use in fire extinguishers and as a pH regulator in various industrial processes. Its ability to decompose into harmless byproducts makes it environmentally friendly in many applications.
