摘要
以鲢鱼皮胶原蛋白和不同多糖为原料制备胶原蛋白-多糖共混膜,通过测定膜的抗拉强度、断裂伸长率、水蒸气透过率、透光率、水溶性等指标,研究多糖对胶原蛋白膜性能的影响。结果表明,壳聚糖/胶原蛋白共混膜的综合性能最佳,当胶原蛋白和壳聚糖的比例为3∶1时,共混膜的力学性能最佳,此时膜的抗拉强度为35.47MPa、断裂伸长率为25.87%,水蒸气透过率、透光率、水溶性较单一胶原蛋白膜有明显的改善。红外光谱、X射线衍射和扫描电镜对其结构进行表征表明,共混膜中胶原蛋白和壳聚糖具有良好的相容性,两者之间存在相互作用。
Sirver carp skin collagen/polysaccharide blend films were prepared by solvent-casting method with silver carp skin collagen and polysaccharide. Tensile strength （TS）, percentage erongation at break （EAB）, water vapor permeability （WVP）, light transmittance and water solubility were determined. The result showed that collagen/chitosan blend film had the best property,and the optimal ratio of collagen and chitosan for preparation blend film was 3：1 （w/w）. At this time,the mechanical property of the blend film was the best,TS was 35.47MPa, EAB was 25.87%. The WVP, light transmittance and water solubility of the blend film were improved. FTIR-ATR, X-RD and SEM analysis revealed that there were strong interactions and good compatibility between collagen and chitosan.
