【摘要】 该文通过单因素试验和正交试验对大豆分离蛋白的成膜性进行研究。结果表明,大豆分离蛋白浓度、增塑剂(甘油)、还原剂(N a2SO3)、交联剂(谷氨酰胺转胺酶)对膜的性能有较大影响,最佳处理条件为:大豆分离蛋白5.0%、甘油1.5%、N a2SO30.1%、TG酶0.2%,大豆分离蛋白浓度对膜性能影响最大,其次是甘油含量,N a2SO3和TG酶的浓度对膜性能影响较小。更多还原

【Abstract】 Filming of soy protein isolate were studied through singlefactor experiments and orthogonal experiment.The results showed that there were significant effects on properties of the soy protein isolate films in different soy protein isolate concentration,plasticizer（glycerin）,reducing agents（Na₂SO₃）,crosslinking agens（TG）;The optimum filming technology was that soy protein isolate was 5.0%,glycerin was 1.5%,Na₂SO₃ was 0.1%,TG was 0.2%.The orders of soy protein isolate films to the effects on properties,first was soy protein isolate concentration,second was the concentration of glycerin,the last was the concentration of Na₂SO₃ and TG.更多还原
