Preparation and antioxidant capacities of oligochitosan-collagen peptide complexe
To meet the demand of food, pharmaceutical and cosmetics industry, study on the oligosaccharide- collagen peptide complexes has both scientific significance and application values. In the text, the preparation process and antioxidant capacity of oligochitosan-collagen peptides complexes were reported. The resultes indicated that the maximum DPPH radical-scavenging activity of oligochitosancollagen peptide complexe was reached to 19.26 ％ when the ratio of oligochitosan to collagen peptide was 80:20, and the activity was stronger than the oligochitosan and collagen peptide at the same concentration in the detection range. In combination with the results of ion-exchange chromatography, we could concluded that the intermolecular chain associations were formed between oligochitosan chains and collagen peptide molecules driven by the electrostatic, intermolecular hydrogen bond and hydrophobic interactions. The results opened a new perspective on the utilization of oligochitosancollagen peptide complexes as drug, food or cosmetic additives.
