Monosodium Glutamate As A Flavor Enhancer

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid found naturally in many foods. It is produced commercially through the fermentation of carbohydrates, such as from corn or sugarcane, by specific bacteria. This process yields a white crystalline powder that enhances savory flavors.

MSG is used as a flavor enhancer to add an umami or savory taste to foods. It is often found in processed foods like sauces, frozen meals, soups, and snack foods. Manufacturers add it to boost the natural savory notes of ingredients and create a more satisfying flavor profile.

In the U.S., MSG is generally recognized as safe (GRAS) by the FDA. The FDA requires that foods containing added MSG list it on the ingredient label. While some individuals report sensitivity to MSG, scientific studies have not consistently shown a direct link between typical MSG consumption and these symptoms. JECFA and EFSA have evaluated MSG and found it to have no safety concerns at typical intake levels.
