摘要: 研究环境温度对明胶-普鲁兰多糖膜机械性能、氧气透过率、水蒸气透过率、油脂透过率、颜色和溶水性的影响,并比较温度对明胶膜、明胶-普鲁兰多糖膜和普鲁兰多糖膜的影响。结果表明:环境温度升高提高了明胶-普鲁兰多糖膜的机械性能,而对其阻水性、阻氧性、阻油性和溶水性没有显著的影响,明胶-普鲁兰多糖膜有轻微的黄化。明胶-普鲁兰多糖膜的抗拉强度、阻水性、阻氧性能优于明胶膜和鲁兰多糖膜。

Abstract: The effect of ambient temperature on mechanical properties, water-vapor permeability, oxygen permeability, oil permeability, color and water solubility of gelatin-pullulan-based film, gelatin film and pullulan film was comparatively studied. The mechanical properties of gelatin-pullulan-based film were improved at higher ambient temperature, while neither the barrier properties nor water solubility was influenced. Moreover, the color was slightly yellowed. The tensile strength of gelatin-pullulan-based film was stronger than that of gelatin film and pullulan film.

Key words: gelatin, pullulan, edible film, ambient temperature
