What Is MSG and How Does It Work
Monosodium glutamate (MSG) is a flavor enhancer commonly added to foods to boost their savory taste. Chemically, MSG is the sodium salt of glutamic acid, an amino acid that occurs naturally in many foods like tomatoes, cheese, and mushrooms. While glutamic acid is a naturally occurring component of protein, MSG is the purified, crystallized form that is specifically used to amplify flavor.
