摘　　要：考察了通过添加碳酸钙、氧化钙、石英矿粉、磷酸氢钙到大豆分离蛋白复合膜中,通过环氧基交联剂作用后,考察几种无机物的蛋白复合膜性能的变化,对比发现:膜机械强度变化为磷酸氢钙>石英矿粉>碳酸钙>氧化钙,对比空白样品,性能有一定提高。通过溶胀系数考察了其交联程度,试验提供了复合膜的交联依据。通过3种溶剂实验发现:石英矿粉大豆复合膜交联程度较理想。This paper investigated the properties changes of four different kinds of soy protein isolate-based composite film by adding calcium carbonate,calcium oxide,quartz powder,calcium hydrogenphosphate,and the epoxy group cross-linking agents.The test results showed the improvement effect of different content of crosslinking agents on mechanical properties of soy protein isolate-based edible film were.calcium hydrogenphosphate quartz powder calcium carbonatecalcium oxide.The properties of the four different kinds of film had improved by comparing with the blank film sample.By fibre swelling coefficients,the degree of crossinking was determined.The experimental results provided the basis for the practical applications of cross-linked Composite Film.Through three kinds of solvents swelled the film,the test results showed the quartz powder was the best.
