MSG seasoning, or monosodium glutamate, is a flavor enhancer used in cooking to intensify the savory taste known as umami, which is one of the five basic tastes alongside sweet, sour, salty, and bitter. MSG is the sodium salt of glutamic acid, an amino acid naturally found in many foods including tomatoes, cheese, mushrooms, and seaweed. The glutamate in MSG is chemically identical to the glutamate found in natural foods and is metabolized by the body in the same way. MSG is commonly used to enhance the flavor of sauces, soups, broths, and processed foods. It adds a savory, meaty flavor to dishes without adding significant sodium—actually containing about one-third the sodium of table salt—and can be used as a partial salt substitute. MSG was first isolated in 1908 from seaweed broth by the Japanese chemist Kikunae Ikeda, who identified glutamate as the substance responsible for the umami taste. Despite misconceptions, studies have shown that MSG is generally recognized as safe by food regulatory authorities like the U.S. FDA and the WHO. It has been extensively tested and does not cause adverse effects when consumed in normal amounts in food. In summary, MSG seasoning is a well-known, safe, umami- enhancing food additive that can enrich the taste of various savory dishes by imparting a rich, meaty flavor. It is widely used in both Asian and global cuisines as a seasoning and flavor enhancer. If you want to try it at home, you can use MSG as a white crystalline powder, often blended with salt to reduce sodium intake while maintaining flavor.
