Monosodium glutamate, also known as sodium glutamate, is the sodium salt of glutamic acid.
It is a flavor enhancer often added to restaurant foods, canned vegetables, soups, deli meats and other foods.
MSG is found naturally in some foods including tomatoes and cheese in this glutamic acid form.
It is used commercially in broths, soups, canned and frozen vegetables, flavouring and spice blends, gravies, meats, poultry, and sauces and in other combinations.
