Food-grade ammonium chloride is primarily produced by recrystallizing agricultural or industrial ammonium chloride through a series of specialized processes including dissolution and filtration.

Food-grade ammonium chloride features high purity, low heavy metal ion content, controllable particle size, and stable pH value. It is widely used in bread leavening improvement, yeast cultivation, soy sauce catalysis, sausage casing production, and other industries. It is also regarded as a safe alternative to liquid ammonia in the water supply industry for chloramine disinfection.
