The main component of monosodium glutamate is sodium glutamate, which is usually about 90%. On the one hand, monosodium glutamate has a strong meat flavor. In addition, after monosodium glutamate enters the human body, it can quickly decompose glutamic acid, which is also an essential amino acid for the human body and is particularly helpful for intellectual development. However, the human body can also synthesize glutamic acid by itself, and it does not depend entirely on food supply.
