氨基酸工业回顾与发展趋势（Review and development trend of amino acid industry） Amino acids are the basis of all life. The scientific community agrees that the earth must be made up of amino acids Acid, and then life. Although scientists have already revealed the chemical structure of amino acids, amino acids are a type of amino acid The history of industrial products has only been over half a century. The earliest industrialized production of amino acids in the world was Kikuchi Shigexiong, creator of the Japanese Ajinomoto Co. Kikuchi is a chemistry expert. At the beginning of 1940s, he was in fact In the laboratory, it was found that a white needle like crystal can be extracted in kelp soaking solution. Taste the thing with your tongue The substance has a strong umami taste, and chemical analysis shows that it is a sodium salt of glutamic acid (named after chrysanthemum) It is still used today. There is no doubt that Su Wei has broad market prospects, but kelp contains The amount is too low to be used as industrial raw material. In order to find cheap raw materials suitable for industrialized production of flavor, chrysanthemum The earth and its assistant did countless experiments. Finally, we have found a new way of industrialization, namely, the use of flavor The rest of the starch processing wheat flour after wheat gluten (common name gluten) as raw materials, it is first hydrolyzed by hydrochloric acid Monosodium glutamate (glutamic acid), then add soda and can obtain food grade sodium glutamate (MSG). Pyromucic (glutamic acid) is the worlds first industrially produced amino acid single product. Since then, scientists have used proteins The hydrolysis of feather, human hair and pig blood can be hydrolyzed into amino acids, but these amino acids are mostly mixed Amino acids (composed of several amino acids) are very difficult to separate. Industrial microorganisms established in 60s The fermentation process started the amino acid industry to take off. Since then, many commo
