| titleOfInvention | A kind of refining and drying method of protease |
| abstract | The invention discloses a method for purifying and drying protease. The method comprises the following steps of: firstly extracting crude protease raw materials with a sodium salt solution to improve the solubility of the protease; Obtain relatively pure protease extract, then use bag filtration method and microfiltration filtration method to further filter and purify the protease extract, and then use ultrafiltration to concentrate and desalt to obtain pure protease concentrate, and finally use vacuum freezing. The dryer performs vacuum freeze drying on the protease concentrate. The protease purification method in the present invention is simple and efficient, the obtained protease has high purity, high activity and stability, and is easy for industrial production. Using the vacuum freeze-drying method and the vacuum freeze-drying machine of the present invention to dry the protease concentrate has the advantages of fast drying speed, low energy consumption and high drying rate, and the obtained protease product has high enzymatic activity, good enzymatic activity stability and good hygienic quality. |
