  FDA Backgrounder: FDA and Monosodium Glutamate
Monosodium glutamate (MSG) is used as a flavor enhancer in a variety of foods prepared at home, in restaurants, and by food processors.
MSG is the sodium salt of the amino acid glutamic acid and a form of glutamate.
Glutamate itself is in many living things: It is found naturally in our bodies and in protein-containing foods, such as cheese, milk, meat, peas, and mushrooms.

 The Discovery of Umami
Glutamate is an amino acid, and is a building block of protein.
To be used as seasoning, glutamate had to have some of the same physical characteristics which are found, for example, in sugar and salt: it had to be easily soluble in water but neither absorb humidity nor solidify.
Because monosodium glutamate has no smell or specific texture of its own, it can be used in many different dishes where it naturally enhances the original flavor of the food.

 Ingredients -- Monosodium glutamate
Glutamic acid is a component of many proteins, such as those in dairy products, meat, legumes, and mushrooms.
Glutamates can be produced by fermentation of starches or sugars, but also by breaking the bonds between amino acids in proteins, leaving free amino acids.
However, free glutamate, as found in soy sauce or prepared foods, enters the bloodstream much faster than the glutamates bound in proteins, where they are released slowly during digestion.

On December 13, 1994, a legal document referred to as a Citizen Petition was filed with the FDA requesting that the FDA initiate a regulation that would cause all processed food to be measured post-production for free glutamic acid, the processed food component that consumers refer to as monosodium glutamate (MSG).
The FDA requires that the ingredient “monosodium glutamate” be listed on the labels of foods in which it is used.
However, free glutamic acid is also found, in varying amounts, in over 40 other labeled ingredients whose names give no clue to the fact that free glutamic acid is present as a component of the ingredients.
