摘要
比较了11种乳化剂对大豆分离蛋白膜水蒸气透过率的影响,结果显示蜂蜡、斯潘60和斯潘40对膜阻水性能具有最佳改善效果。进一步研究了这3种乳化剂单一添加和复合使用时对大豆分离蛋白膜水蒸气透过率的影响,得出复合使用不如单一使用时改善效果好,且3 g/L质量浓度的蜂蜡对大豆分离蛋白膜阻水性的改善作用最好,使水蒸气透过率达到18.93 g.mm/(m2.d.kPa),缩减为未加乳化剂时的54%。
Eleven kinds of emulsifiers were evaluated to improve the water vapor permeability （WVP） of edible film from soy protein isolate. The results showed that the films with beeswax, span60 and span40 possesed better WVP. Furthermore, the improving effect of WVP by adding single emulsifier or composite emulsifiers were researched, as a result, the films with composite emulsifiers showed worse WVP than that with the single emulsifier. In addition, the film with beeswax （mass concentration 3 g/L） presented the best WVP [ 18.93 g· mm/（ m^2 · d· kPa） ] ,which was 54% of the control.
