Monosodium glutamate, also known as monosodium glutamate, is a kind of seasoning, and its main component is sodium glutamate. It should be noted that if monosodium glutamate is used at a high temperature above 100℃, the flavor agent sodium glutamate will be transformed into sodium pyroglutamate which is carcinogenic to human body. And if in alkaline environment, monosodium glutamate will react chemically to produce a substance called disodium glutamate. Therefore, it should be used and stored properly. Sodium glutamate is a sodium salt of amino acid glutamic acid. It is an odorless and colorless crystal that disintegrates and melts at 232 C. The water solubility of sodium glutamate is very good, and 74 grams of sodium glutamate can be dissolved in 100 ml of water.
