| titleOfInvention | Preparation method of collagen peptide with high antioxidant activity |
| abstract | The invention discloses a preparation method of collagen peptide with high antioxidant activity, which comprises the following steps: adding trypsin to the collagen liquid of livestock and poultry with an enzyme specific activity of 5000 U/g for hydrolysis to obtain a hydrolyzed liquid; After inactivating the enzyme, centrifuging and drying to obtain the collagen peptide; diluting the collagen peptide to obtain a collagen peptide solution, and dissolving D-galactose in the collagen peptide solution at a ratio of 1:1 to obtain a reaction solution , the pH value of the reaction solution was adjusted to 8.8-9.2, heated in a 93-98 ℃ water bath for 4.5-5.5 h, cooled and centrifuged to obtain the supernatant, and the supernatant was freeze-dried to obtain the N-terminal modified collagen peptide. The invention has the beneficial effect of improving the antioxidant activity of collagen peptides. |
