What it is
Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid that occurs naturally in many foods. It is produced commercially through the fermentation of plant-based ingredients like corn or sugar beets, similar to how yogurt or vinegar is made.
Why it's used
MSG is used as a flavor enhancer to add an umami taste, which is often described as savory or meaty. It is commonly found in processed foods such as soups, broths, seasoned snacks, and savory dishes to boost their overall flavor profile.
Health notes
In the U.S., MSG is generally recognized as safe (GRAS) by the FDA. Some individuals report sensitivity to MSG, experiencing symptoms like headaches or flushing, although controlled studies have not consistently linked these symptoms to MSG consumption at typical levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated MSG, and regulatory bodies worldwide consider it safe for consumption. Research continues to explore any potential effects of MSG.
Allergen info
MSG is not derived from any of the nine FDA major allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, sesame). It does not contain gluten.
