Monosodium Glutamate 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, similar to how yogurt or vinegar is made. MSG is used to enhance the savory (umami) taste of foods.

Manufacturers add MSG to foods to boost their natural savory flavors, creating an umami taste. It is commonly found in processed foods like snacks, soups, sauces, and seasoned meats. It can also be used in restaurant cooking to add depth of flavor.

MSG is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when consumed at typical levels. Some individuals report experiencing short-term symptoms like headaches or flushing after consuming MSG, but controlled studies have not consistently linked these symptoms to MSG. 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. Evidence on widespread adverse effects is mixed and often debated.
