摘要: 本文主要研究了不同添加剂对功能性壳聚糖复合膜的物理和机械性能的影响。结果表明,透湿性和吸湿性分别随壳聚糖(CH)和甘油(GLY)浓度的增加而增加,随蔗糖酯(SUC)、山梨醇酐单硬脂酸酯(SPAN)和大豆分离蛋白(SPI)浓度的增加而减少;拉伸率随GLY浓度的增加而增加,随与CH、SUC、SPAN和SPI浓度的增加而减少;其中,GLY对壳聚糖膜的透湿性、吸湿性和拉伸率影响较大,SUC和SPI对膜透气性影响较大;并用SAS统计分析软件建立了壳聚糖复合膜氧气和二氧化碳透过率的回归方程。

关键词: 壳聚糖, 透湿性, 拉伸率, 透气性

Abstract: This paper studied the effect of different ingredients on the physical and mechanical properties of the edible coatings of chitosan. The results showed that the water vapor permeability(WVP) and the moisture absorption(MB) increased with the increase of the concentration of CH and GLY, and decreased with the increase of the concentration of SUC, SPAN and SPI respectively. The elongation(E) increased with the increase was of the concentration of GLY, and decreased with the increase of the concentration of GLY, SUC, SPAN and SPI respectively. GLY has an maximal effect on WVP, MB and E. SUC and SPI has an great effect on gas permeability. The regressive models of the permeabilities of O2 and CO2 was established by SAS 8.2 respectively.

Key words: chitosan, WVP, elongation, gas permeability
