Darstellung · 1 Eintrag

synthetischeMonosodium 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
