胶原蛋白-葡甘聚糖-壳聚糖共混膜的物理性能和热稳定性
Physical Properties and Thermal Stability of Collagen-Konjac Glucomannan-Chitosan Blend Film
【摘要】 研究了胶原蛋白、葡甘聚糖含量等因素,对胶原蛋白-葡甘聚糖-壳聚糖共混膜(CKCS)的抗张强度、断裂伸长率和溶胀吸水率的影响,同时测定了共混膜的透水气性,并利用热重分析(TGA)法和差示量热扫描(DSC)分析法,考察了共混膜的热稳定性。为共混膜在食品材料领域的应用提供试验依据。
【Abstract】 The influences of the collagen content and konjac glucomannan on tensile strength,tear strength and water absorption of collagen-konjac glucomannan-chitosan blend film(CKCS) were studied.Water vapour permeability was measured and thermal stability was investigated by Thermal Gravitational Analysis(TGA) and Differential Scanning Calorimeter(DSC).It provides useful reference for the application of CKCS as a new edible material in food industry.
