MSG (E621) 98%(40mesh-powder)

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, one of the most abundant naturally occurring non-essential amino acids. Glutamic acid is found naturally in tomatoes , grapes , cheese , mushrooms and other foods. Monosodium glutamate (MSG) is a flavor enhancer or comdiment commonly added to food, canned vegetables, soups and processed meats etc.

Odor: Practically odorless
Taste: Meaty taste comes from contaminants in crude glutamates; sweet-saline taste in large concentration; no flavor in small quantity | A 1% concentration or more is liable to produce a sweetish taste.
Experimental Properties: The monohydrate forms needles | The flavor becomes perceptible at a concentration of 0.03% in distilled water | Below -8 °C, it crystallizes as a pentahydrate, which, after filtration and exposure to air, loses water of crystallization and becomes the monohydrate.
Air and Water Reactions: Water soluble.
