Glutamic acid is a natural essential amino acid that is present in all complete proteins. It is the most common excitatory neurotransmitter in the brain. Glutamic acid has the ability to make bland and tasteless foods taste wonderful. It is very cheap and easy to produce, and is present in a wide variety of foods. Commercially it is prepared by bacterial fermentation of molasses and also prepared from vegetable protein. It is essentially an odourless, white crystal or crystalline powder that is slightly soluble in water. It is used as a flavour enhancer, nutrient, dietary supplement, and as a salt substitute in foods.http://www.creative-enzymes.com/product/Glutamic-Acid_461.html
