| Abstract: | The Progression of Glutamic acid Extraction Abstract： The extraction of glutamic acid has become the issue for MSG manufacturer. This paper discussed the recent extraction of progress of Glu and the direction of future development from the extraction of Glu and the characteristic of Glu acid crystals. In addition ,with the developments of Glu acid fermentation and the cultivation of high yield Glu acid bacte- ria, especially, the application of temperature-sensitive strains, making the continuous improvement of fer- mentation acid production ,therefore ,the suitable high acid fermentation liquid extraction process route has get the majority of glutamate production favor. |
