| 摘 要： | 研究了环境湿度对小麦蛋白膜、大豆蛋白膜以及小麦-大豆复合膜机械性能、通透性等的影响。结果表明,由于蛋白腹为亲水性膜,受环境湿度的影响,其水分含量、分子间作用力有所不同,从而导致蛋白膜的机械性能、透湿性和吸湿率也随之发生变化。膜的阻止水蒸汽渗透的能力下降,吸湿率降低,透氧率呈上升趋势。

| Abstract: | This research studies the effects of relative humidity of environment on wheat protein film, soy protein isolate film and wheat -soy protein film. This result showed that the change of relative humidity led to the variation in mechanical properties, water vapor permeability (WVP), oxygen permeability and moisture absorption of the films. Because the protein films are hydrophilic, relative humidity can affect the moisture content as well as the interactions between molecules. |
