Food Additive of the Week E621 – MSG (Monosodium Glutamate)
Although traditional Asian cuisine had often used seaweed extract, which contains high concentrations of glutamic acid, it was not until 1907 that MSG was isolated by Kikunae Ikeda. MSG was subsequently patented by Ajinomoto Corporation of Japan in 1909.
In its pure form, it appears as a white crystalline powder which rapidly dissociates into sodium cations and glutamate anions on contact with water (glutamate is the anionic form of glutamic acid). Ingestion of MSG is known to produce a variety of adverse reactions in some people. These reactions, although seemingly dissimilar, are no more diverse than reactions found as side effects of certain neurological drugs. We do not know why some people experience reactions and others do not.
