摘要: 明胶-普鲁兰多糖膜是一种可以快速溶解于热水的可食性包装材料,研究环境湿度对明胶-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、颜色以及水溶性的影响,并比较环境湿度对明胶膜、明胶-普鲁兰多糖膜和普鲁兰多糖膜性能的影响。结果显示,较高的环境湿度（80%）会降低明胶-普鲁兰多糖膜的抗拉强度,提高其柔韧性,而对其阻氧性、阻油性和透明度没有显著的影响;明胶-普鲁兰多糖膜的各方面性能优于明胶膜和普鲁兰多糖膜。Abstract: Gelatin-pullulan-based film is a water-soluble package material. The effect of relative humidity on mechanical properties, water-vapor transmission ratio, oxygen transmission ratio, oil transmission ratio, color and water solubility of gelatin-pullulan-based film were evaluated, and the effect of relative humidity on properties of gelatin-pullulan-based film, gelatin film and pullulan film were compared. The relative humidity of 80% lowered the tensile strength of gelatin-pullulan-based film, improved its flexibility, and showed no significant different on its oxygen resistance, oil resistance and transparency. The properties of gelatin-pullulan-based film were better than that of gelatin film and pullulan film in the same relative humidity.
