| titleOfInvention | A kind of process for extracting high-purity medicine rank tryptophan |
| abstract | A kind of process for extracting high-purity medicine rank tryptophan, is related to the method for purification of tryptophan, and first by feed rank tryptophan wet product with being diluted to tryptophan solution after ethyl alcohol recrystallization, and tryptophan solution carries out pasteurization；Then a decolorization, filtering first are carried out with pharmaceutical grade activated carbon tryptophan solution, then secondary decolourization processing, filtering is carried out with the activated carbon tryptophan solution after oxidized dose of processing；The filtrate after secondary decolourization, filtering is diluted with ethanol solution afterwards and 1 2h is incubated at 55 70 DEG C, separate out the protein denaturation in filtrate and filter off, filtrate is concentrated by evaporation after pasteurization, evaporation concentrated solution isolates crystal after being crystallized, then scrubbed, be drying to obtain medical rank tryptophan.The tryptophan finished product purity that the inventive method purifies to obtain is up to medical rank, and process route is simple, replicability is strong. |
