This article added further support to the preparation of natural antioxidative peptides from porcine skin collagen. The results confirmed that the antioxidative peptides were rich in Hyp, Pro and Gly, which accounted for half of amino acid composition. Fraction 2b with abundant basic amino acids and Fraction 2d which was slightly acidic fractions had higher radical-scavenging and metal-chelating activities, and both Fraction 2b and 2d contained more hydrophobic amino acids. Fraction 2 was further separated by ion exchange chromatography. The hydrolysate prepared with the cocktail mixture of proteases, which exhibited the highest antioxidant activity, was separated into 6 fractions by gel filtration chromatography. However, the contents of Hyp and Pro were improved and the content of Gly was decreased in each collagen hydrolysate compared with collagen. The raw materials used in manufacturing are from federally. It was found that the collagen hydrolysates by different protease treatments had different amino acid compositions and antioxidant properties. This type-A gelatin is extracted by hydrolysis of the collagen from non-GMO porcine skins. The hydrolysates were assessed using methods of DPPH radical-scavenging ability, metal-chelating ability and lipid peroxidation inhibition activity. The gelatin was hydrolyzed for antioxidative peptides with various proteases, namely papain, protease from bovine pancreas, protease from Streptomyces, and cocktail mixture of protease from bovine pancreas and protease from Streptomyces. Porcine sources are favored over other sources since they are less expensive. Porcine gelatin is regarded as the leading source of gelatin globally then followed by bovine gelatin. Gelken can provide 100-500g free sample or 25-200KG bulk order for your test.The amino acid composition and antioxidant activities of different hydrolysates from porcine collagen were analyzed.
