Spices And Monosodium Glutamate

Spices are a diverse group of plant-derived substances used to flavor food. They can be seeds, fruits, roots, bark, or vegetative substances. Monosodium glutamate (MSG) is a sodium salt of the amino acid glutamic acid, a common flavor enhancer found naturally in many foods like tomatoes and cheese, and also produced commercially through fermentation.

Spices add flavor and aroma to a wide variety of foods. MSG is primarily used as a flavor enhancer to provide an umami taste, which is often described as savory or meaty. It is commonly found in processed foods like soups, sauces, snacks, and savory dishes.

Spices are generally recognized as safe (GRAS) by the FDA when used for flavoring. MSG is also GRAS for use in food. Some individuals report sensitivity to MSG, experiencing symptoms like headaches or flushing, though scientific studies have not consistently shown a causal link at typical consumption levels. JECFA and the FDA have evaluated MSG and found it safe. The WHO/IARC has not classified MSG regarding carcinogenicity.
