Discussion: The quality of monosodium glutamate (MSD) depends on its production method.

Monosodium glutamate is a salt of glutamic acid with one of the five primary flavors (umami) and is identified as a meaty flavor. Only free glutamic acid affects the taste. When MSG is produced in a biological, natural product, it is not harmful at a reasonable dose. Production of MSG by industrial means may harm taste and our health. When buying Chinese soy sauce, which contains a vast amount of MSG, it is essential to ensure that its production form is biological-natural.
