Ammonium bicarbonate is widely used in the food industry as a leavening agent in baked goods like cookies, crackers, and flatbreads. It releases carbon dioxide when heated, causing dough to rise and creating a light, airy texture. It is also employed in the production of ceramics and plastics as a foaming agent, helping to create porous structures. In agriculture, it serves as a nitrogen source in fertilizers, promoting plant growth. Additionally, it is used in fire extinguishers as a flame retardant and in the pharmaceutical industry as a buffering agent in certain medications. Its ability to decompose into harmless gases makes it a preferred choice in various applications.
