Abstract

To develop the protein materials by the reutilization of dead flatfish from fish farms in Jeju island, the physicochemical characteristics and the functional activities of collagen peptide extracts were investigated. Flatfish skin collagen peptide (FSCP) and flatfish protein hydrolysate (FPH) were manufactured from dead flatfish. The differences of pH, moisture and fat contents between FSCP and FPH were not significant, fat contents were analyzed less than 0.3%, and trans-fat, saturated fat and cholesterol were not detected in both samples. Protein contents of FSCP and FPH showed about 92% and 95%, respectively. In the analysis of amino acids, glycine and hydroxy proline content in FSCP was 24.22% and 6.15%, respectively, showed a typical characteristics of the collagen protein, but essential amino acids contents such as threonine, valine, methionine, isoleusine, leusine and phenylalanine were relatively higher than those of FPH. Average molecular weight of FSCP was measured as 1,102 which was almost equal value with that of tuna collagen peptide. The antioxidant activities and functional properties showed high but did not show significant difference between two samples.
