Ammonia is essential for life. This naturally occurring substance is found in virtually all life forms, from plants to animals to humans. Life could not have evolved and cannot survive without it. Ammonia, in the form of ammonium hydroxide, is naturally found in beef, other proteins, and virtually all foods. It is widely used in the processing of numerous foods, such as baked goods, cheeses, gelatins, chocolate, caramels, and puddings.
