【摘要】 冻藏温度对玉米醇溶蛋白膜特性有一定影响。结果表明:蛋白膜的机械特性、平衡水分含量和水蒸气透过率随冻藏温度的变化而发生变化。随着冻藏温度的降低,蛋白膜的抗拉强度和延伸率都呈下降的趋势;蛋白膜的平衡水分含量随冻藏温度的降低先上升,而后又略有下降;水蒸气透过率随冻藏温度的降低而上升。更多还原

【Abstract】 The properties of zein films were effected by freezing storage temperature. The results showed that temperature of freezing storage had influences on the zein films, which led to the changes of mechanical properties, equilibrium moisture content (EMC), water vapor permeability (WVP). Tensile strength (TS) and elongation (E) of zein films decreased with the decreasing of freezing storage temperature; The EMC increased with the decreasing of freezing storage temperature, but then it had a little decrease; With the decreasing of freezing storage temperature, the WVP of zein films showed an increase.更多还原
