| 目的 对可食用保鲜膜的性能进行拓展。方法 采用层层自组装静电沉积法制备可食用水果保鲜膜，并对膜进行表征，探究膜的微观结构、透明度、亲疏水性、自修复性等。结果 该可食用膜结构致密，具有较好的透明度，透光率在90%以上；具有较好的疏水性，接触角θ约为102°；能实现形貌和力学性能上的修复，修复前后的膜都能负载 200 g的砝码，同时都无法负载300 g的砝码。结论 可食用保鲜膜的这些性能提高了该可食用膜的保鲜效果。 |
| 英文摘要: |
| The work aims to extend the properties of edible fresh-keeping film. Edible fruit fresh-keeping film was prepared with the layer-by-layer self-assembly electrostatic deposition technology. Meanwhile, the microstructure, transparency, hydrophilic-hydrophobic property and self-healing ability of the edible film were characterized. The edible film was of dense microstructure and high transparency, with the transmittance above 90%; the film was of high hydrophobicity and the contact angle θ was about 102°; the edible film could self-heal morphologically and mechanically and the edible film and self-healed film could hold the weight of 200 g and could not hold the weight of 300 g. It is concluded that these properties of edible fresh-keeping film have improved the fresh-keeping effect of the edible film. |
