Monosodium Glutamate(MSG, also known as Sodium Glutamate) is the
sodium salt of glutamic acid, one of the most abundant naturally
occurring non-essential amino acids. Monosodium glutamate is found
naturally in tomatoes, cheese and other foods.
MSG is used in the food industry as a flavor enhancer with an umami
taste that intensifies the meaty, savory flavor of food, as
naturally occurring glutamate does in foods such as stews and meat
soups.
