titleOfInvention | Production method of small molecule sodium hyaluronate |
abstract | The invention relates to a production method of micromolecular sodium hyaluronate, which takes fermentation liquor obtained by producing hyaluronic acid by a fermentation method as a raw material, directly carries out degradation treatment, and can utilize the same process flow to realize the production of sodium hyaluronate with different molecular weights on the same equipment by adjusting process parameters. According to the invention, the earlier-stage degradation of sodium hyaluronate is utilized to enlarge the concentration of sodium hyaluronate in a dissolving process to 10-50 g/L, so that the time consumption of each subsequent process is greatly shortened, the use amount of ethanol and inorganic salt is reduced, and meanwhile, the yield of the product is higher than that of the common molecular weight sodium hyaluronate and the conventional small molecular weight sodium hyaluronate production process due to the reduction of the dissolving volume. |
