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 is modified by adding various auxiliary agents in the saturated solution of soybean protein and then modified and modified with the acidic reagent S to denature the soy protein from the solution. Good toughness and water resistance, the elongation at break can reach 200%, saturated water absorption of 10% or less. This method does not require glycerol and other small molecule alcohol as a plasticizer, well to avoid small molecule alcohol plasticizer in the air volatilization and dissolution in water.
