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. |
