【摘要】 以豌豆分离蛋白（PPI）为原料，添加卡拉胶（CGN）制备豌豆蛋白—卡拉胶（PPI-CGN）复合膜，并研究超声处理对复合膜性能的影响。结果表明：超声处理显著提高了PPI-CGN复合粒子的Zeta电位绝对值和复合膜的机械性能、阻隔性及溶胀度（p<0.05）；降低了复合粒子的粒径和复合膜的厚度、溶解度及水分含量（p<0.05）。与豌豆蛋白膜相比，经超声处理的PPI-CGN复合膜的粒径、Zeta电位绝对值、机械性能、水分含量、阻隔性均显著提高（p<0.05）；水溶性显著降低（p<0.05）。更多还原

【Abstract】 Pea protein isolate(PPI) was used as material, pea protein-carrageenan(PPI-CGN) composite membrane was prepared by adding carrageenan(CGN). The effect of ultrasonic treatment on the properties of composite membrane was studied. The results showed that: Ultrasonic treatment significantly improved the absolute value of Zeta electric potential for the composite particles, mechanical properties, barrier property and swelling degree of PPI-CGN composite membrane(p <0.05); The composite particle size, thickness,solubility and moisture content of composite membrane were decreased(p<0.05). Compared with pea protein membrane, the particle size, absolute value of Zeta electric potential, mechanical properties, moisture content and barrier property of the composite membrane treated by ultrasound were significantly improved(p<0.05); Water solubility was significantly reduced(p<0.05).更多还原
