I think there is a difference between chicken essence and monosodium glutamate (MSG) in terms of composition, color, form, taste and use. The ingredients of chicken essence include monosodium glutamate and chicken powder, small yellow granules with a strong aroma; the main ingredient of monosodium glutamate is monosodium glutamate, which is colorless and transparent, powdered or crystalline, with a light taste, and is mainly used to add flavor to food.
