摘　　要：研究干燥温度对大豆分离蛋白/羧甲基纤维素复合膜的影响。结果显示90℃干燥复合膜的厚度较其他复合膜显著降低(p<0.05),密度显著提高(p<0.05),其抗拉伸强度是30℃干燥复合膜的2.64倍(p<0.05)、水蒸气透过率仅为30℃干燥复合膜的78%(p<0.05)。干燥温度90℃显著提高复合膜的性能。The effect of drying temperature on properties of soybean protein isolate/carboxymethyl cellulose composite films was evaluated. The drying temperature of 90℃ lowered the thickness of the composite films and enhanced their density significantly（p〈0.05）. The tensile strength and water vapor permeability of the composite films dried at 90℃ was 2.64 time and 78% of those of the composite films dried at 30℃, respectively. The drying temperature of 90℃ improved the performance of the composite films effectively.
