제조 방법
Monosodium glutamate is commonly produced by a fermentation process using glucose (often sugar molasses) as a starting substance. Once the glucose is converted to glutamic acid, it is filtered, dissolved and converted to monosodium glutamate by neutralization with sodium hydroxide. The monosodium glutamate solution is decolorized and then crystallized, dried, sieved, packed and shipped
생산 방법Monosodium glutamate is the monosodium salt of the naturally occurring L-form of glutamic acid. It is commonly manufactured by fermentation of carbohydrate sources such as sugar beet molasses. In general, sugar beet products are used in Europe and the USA. M 452 Monosodium Glutamate Other carbohydrate sources such as sugar cane and tapioca are used in Asia.
