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.

摘  要:
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.
