APPLICATIONS

Monosodium Glutamate, commonly known as MSG, is a sodium salt of an amino acid (L-glutamic acid). It is a white crystalline substance soluble in water and alcohol; practically odorless. MSG is used to intensify flavours of foods. It is produced by a bacterial fermentation process with starch or molasses as carbon sources and ammonium salts as nitrogen sources (Steffen process). MSG is not a direct taste enhancer but a complex flavour enhancer for gravies, meats, poultry, sauces, and in other combinations. It is also used to enhance the taste of tobacco and has been used medically to treat hepatic coma.
