More Information
Summary:The invention relates to the field of Chinese medicine, in particular to a preparation method of ginseng peptide. The preparation method includes the following steps of A, a multilevel countercurrentextraction method, wherein air-dried raw ginseng powder is obtained and smashed into coarse powder, five-level countercurrent extraction is carried out, the pH value is 7-9, and the extraction temperature is 50 DEG C; B, an enzymolysis process, wherein an extracted filtrate is put into an enzymolysis tank, hydrochloric acid is added to adjust the pH value to be 1-2, ginseng hydrolase is added, thespecific proportion of protease to protein is 3,500:1, the temperature is 35-40 DEG C, enzymolysis is conducted for 3.5 hours, a sodium hydroxide weak solution is adopted for adjusting the pH value to be 8-9 after enzymolysis, ginseng hydrolase is added, the specific proportion of chymotrypsin to protein is 2,500:1, the temperature is 35-40 DEG C, hydrolysis is conducted for 7 hours, and stirringis conducted for 5 minutes
