Abstract:
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.
