摘要
为制备机械性能和阻水性能良好的壳聚糖/酪蛋白酸钠可食包装材料,采用Box-Behnken试验分析壳聚糖/酪蛋白酸钠质量比、pH值和甘油质量分数对复合膜性能的影响。综合考虑响应面模型优化结果和实际应用的便捷性,确定可食性膜的最佳制备工艺。结果表明,当壳聚糖/酪蛋白酸钠质量比为4∶1、pH为4.5、甘油质量分数为0.75%时,复合膜的综合性能最优。
The work aims to prepare chitosan/sodium caseinate edible packaging material with good mechanical properties and water resistance.The Box-Behnken test was used to analyze the effects of chitosan/sodium caseinate mass ratio,pH value and glycerol mass fraction on the property of the composite film.Considering the optimization results of response surface model and the convenience of practical application,the optimal preparation process of the edible film is determined.The results showed that chitosan/sodium caseinate mass ratio of 4:1,pH value of 4.5,glycerol mass fraction of 0.75%showed the best comprehensive property of the composite film.
