Preparation technology of collagen films from fish scales of grass carp Cetnophayrngodon idellus

以酸-酶法提取的草鱼鱼鳞胶原蛋白为材料,采用倾注法制备胶原蛋白膜,研究成膜条件、多糖等对鱼鳞胶原蛋白膜(fish scale collagen film,FCF)特性的影响,考察鱼鳞胶原蛋白膜制备条件。结果表明:成膜条件、多糖等对鱼鳞胶原蛋白膜特性有显著影响,适宜的制备工艺条件为成膜温度45℃p、H 5、胶原蛋白与壳聚糖配比6∶4,该条件下胶原蛋白膜的抗张强度为61.27 MPa,断裂伸长率为5.17%。

Collagen was extracted from grass carp scale with acid-enzyme combination-method for preparing fish scale collagen film（FCF） by the plate pouring method.The film-forming conditions and chitosan on the properties of gelatin film were studied to optimize the preparation conditions of FCF.The results showed that the conditions forming scales and polysaccharides have significant effects on the fish scale collagen membrane characteristics.The optimum conditions were 45 ℃,pH 5,collagen/chitosan=6∶4.The tensile strength was 61.27 MPa,and elongation at break was 5.17%.
