Monosodium Glutamate (MSG) – CAS No. 142-47-2

Monosodium Glutamate (MSG), chemically known as C₅H₈NNaO₄ with CAS Number 142-47-2, is a naturally occurring sodium salt of glutamic acid, serving as a versatile flavor enhancer that imparts umami taste to foods. This white, odorless crystalline powder exhibits high solubility in water (74 g/100 mL at 20°C) and a neutral pH of 6.7-7.2 in 1% solution, making it ideal for seasoning, processing, and fortification without altering color, texture, or stability.
