Outline of Final Research Achievements |
In order to obtain collagen from fish scales, conditions to extract using fine bubbles were investigated as a simple and low cost extraction method. As a result, when oxygen, carbon dioxide, ozone, or air was used as the bubble gas, collagen extraction rate was low, there was no difference depending on the kind of gas. However, it was found that deodorizing effect was observed only when ozone was used, and decomposition of collagen was also promoted. The extraction temperature was optimum around 40 ° C. In addition, when the scales were crushed, the yield exceeded 70% over, but it became clear that they were collagen peptide rather than collagen. It was also revealed by GPC that irradiation with artificial sunlight after crushing promotes crosslinking of collagen peptide molecules.
