摘　　要：通过在大豆蛋白质饱和溶液中添加各种助剂对大豆蛋白质进行改性处理,然后使用酸性试剂S对大豆蛋白分子进行修饰改性并将大豆蛋白质从溶液中沉淀出来,得到的改性大豆蛋白质具有很好的韧性和耐水性,其断裂伸长率能达到200%,饱和吸水率在10%以下。此方法无需甘油等小分子醇作为增塑剂,很好地避免了小分子醇类增塑剂在空气中的挥发和在水中的溶出问题。The soybean protein was modified by adding various additives in soy protein saturated solution first, and then the acid reagents S was used to precipitate soy protein from solution,the modified soy protein was got which had good toughness and water resistance, the elongation at break could achieve 200 % and saturated water absorption was below 10 %. This method used no alcohol glycerol or other small molecules as plastieizers,it avoided the plasticizer volatile to the air and dissolution in water.
