Flavor Enhancers: Monosodium Glutamate

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 like corn starch, sugar beets, or sugarcane.

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 seasoning mixes, bouillon, sauces, and processed foods to boost their overall flavor profile.

MSG is generally recognized as safe (GRAS) by the FDA for use in food. Some individuals report sensitivity to MSG, experiencing symptoms like headaches or flushing, though scientific studies have not consistently linked these symptoms to MSG consumption at typical dietary levels. JECFA and EFSA have evaluated MSG and established acceptable daily intakes. While some concerns have been raised in popular media, regulatory bodies and major scientific reviews have found no consistent evidence of widespread adverse reactions in the general population when consumed at normal levels.
