In order to obtain chicken essence products with good color, fragrance and shape, the choice of accessories is very important. Among them, the quality of monosodium glutamate semi-finished product (sodium glutamate) and oil fetus plays a decisive role in the quality of chicken essence finished product. In terms of drying, the main component of chicken essence is sodium glutamate, which will become the focus when the temperature is higher than 120 ℃.
