Ajinomoto monosodium glutamate is made through a naturally fermented process similarly like how we make soy sauce, yogurt, vinegar or beer, but usually made with carbohydrates like sugar cane, corn, and beet. It is then purified and crystalized after fermentation for it's whiteness. It is essentially used as a taste enhancer.
