Many countries in the world are using monosodium glutamate. As a flavoring agent, monosodium glutamate is really used in East Asian countries, especially in China and Japan. Especially in countries and regions with relatively developed economies. Monosodium glutamate can increase the freshness of food and increase people's appetite. Westerners believe that eating monosodium glutamate is harmful to health, but practical science has proved that monosodium glutamate, the main component of monosodium glutamate, is made of pure grain and has no toxicity itself, so it will not be harmful to health when used as a food additive. However, because this concept has a long history and eating habits are hard to change, westerners still use monosodium glutamate less.
