A: Ammonium hydroxide and other ammonia-containing compounds are used extensively in food processing. Food and Drug Administration (FDA) regulations affirm ammonium hydroxide as safe (“generally recognized as safe” or GRAS) for use as a leavening agent, a pH control agent, and a surface-finishing agent in food with no limitation other than current good manufacturing practice. 21 C.F.R. § 184.1139. See also National Academy of Sciences, Food Chemicals Codex, 5th Ed. (2004), p. 24.
A: Many food pathogens, including dangerous forms of E. coli can be found in the intestines of cattle. They are able to survive and grow in the high acid tissues of animals. Ammonium hydroxide and other compounds can damage these organisms and lower the acidity of meats and other foods, making it difficult for these pathogens to survive.
Q: What about use of ammonium hydroxide in meat products?
Quaternary ammonium salts are used as , , , and as (e.g. in ). In fabric softeners, the salts are often used. In strips, the salts are often used. Spermicidal jellies also contain quaternary ammonium salts.
making a quaternary ammonium salt.
Quaternary ammonium compounds are prepared by of tertiary amines, in a process called quaternization. Typically one of the alkyl groups on the amine is larger than the others. A typical synthesis is for from a long-chain alkyldimethylamine and :

Quaternary ammonium cations, also known as quats, are positively charged of the structure NR4+, R being an group. Unlike the (NH4+) and the primary, secondary, or tertiary ammonium , the quaternary ammonium cations are permanently charged, independent of the of their solution.

A: Ammonium hydroxide is ammonia combined with water. Ammonia (NH3) is a compound consisting of nitrogen and hydrogen. Both ammonia and ammonium hydroxide are very common compounds, found naturally in the environment (in air, water, and soil) and in all plants and animals, including humans. Ammonia is a source of nitrogen, an essential element for plants and animals. Ammonia is also produced by the human body – by our organs and tissues and by beneficial bacteria living in our intestines.
