Monosodium

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid naturally found in many foods. It is produced commercially through the fermentation of starch, sugar beets, sugarcane, or molasses.

MSG is used to enhance the savory "umami" taste in foods. Manufacturers add it to a wide variety of processed foods, including seasonings, soups, processed meats, and snacks, to boost their flavor profile.

MSG is Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA). Some people report sensitivity to MSG, experiencing symptoms like headaches or flushing, though scientific studies have not consistently shown a link between MSG consumption and these symptoms in the general population. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated MSG and established an acceptable daily intake.
