| titleOfInvention | Preparation method for extracting active protein peptide from weever |
| abstract | The invention relates to the technical field of biological enzymolysis extraction, in particular to a preparation method for extracting active protein peptide from weever, which comprises the following steps: s1, raw material treatment: cutting off the skin of the weever, scraping and removing the fish adhered to the skin, cleaning, cutting into pieces, and freeze-drying for later use; s2, soaking: soaking the fish skin treated in the step S1 in a sodium chloride or sodium carbonate solution with the mass concentration of 5-10%, stirring, filtering, washing with distilled water, and repeating for a plurality of times; s3, enzymolysis: adding distilled water into the fish skin obtained in the step S2, hydrolyzing and extracting collagen peptide by using alkaline protease, wherein the enzymolysis temperature is 45-65 ℃, the enzymolysis time is 4-5 h, preparing the collagen peptide by performing enzymolysis on the weever skin by using the alkaline protease, and obtaining the optimal process condition for preparing the collagen peptide of the weever skin by controlling the influence of 5 factors on the peptide yield in the enzymolysis process, such as temperature, time, pH, enzyme adding amount and feed-liquid ratio, so as to effectively improve the yield of the collagen peptide. |
