l-glutamic acid
one of the 20 common amino acids, occurs naturally in food such as cheese, milk, meat, fish, corn,tomatoes, mushrooms, soybean and sugar beet. in its free form, l-glutamic acid is the major flavour enhancing component of foods with a meaty / savoury taste. the role played by l-glutamic acid in the palatability of foods is exploited by either traditional cooking methods that release free l-glutamic acid, or by supplementation with monosodium glutamate.
