1. Ordinary monosodium glutamate: Ordinary monosodium glutamate consists of sodium glutamate and sodium ribose. Glutamate is a naturally occurring amino acid in food, which can increase the delicacy of food.

2. No added monosodium glutamate: No added monosodium glutamate is the removal of synthetic additives such as sodium nitrite on the basis of ordinary monosodium glutamate. Sodium nitrite is a preservative, which will produce carcinogens at high temperature, so it is safer and healthier not to add monosodium glutamate.
