| 目的 研究一种含微胶囊的抗菌淀粉膜制备工艺， 并对其性能进行评价。方法 以淀粉作为成膜基材， 加入具有抗菌性的微胶囊， 以及明胶、 甘油、 CaCl2等助剂， 采用流延法制备出含微胶囊的抗菌淀粉膜。将淀粉/甘油/明胶的质量比、 微胶囊含量、 CaCl2含量、 干燥温度作为影响因素， 进行正交试验，选取膜的水溶性、 力学性能、 抗菌性能作为指标， 对其性能进行检测和综合评价。结果 当淀粉/甘油/明胶质量比为6∶3∶1， 微胶囊质量分数为20%， CaCl2质量分数为2%， 干燥温度为50 ℃时， 薄膜具有较好的综合性能。结论 通过加入丁香精油微胶囊， 制得的淀粉基薄膜具有抗菌性。 |
| 英文摘要: |
| The preparation process of an antimicrobial starch-based film containing microcapsule was introduced, and the properties of the film were investigated. In this paper, starch was used as the base material of film, and then antimicrobial microcapsules as well as auxiliary agents including gelatin, glycerin and CaCl2 were added into it to prepare the antimicrobial starch-based films containing microcapsule by casting technique. Using m(starch) ∶ m(gelatin) ∶ m(glycerin), content of microcapsule and CaCl2, reaction temperature as factors, orthogonal experiments were conducted. After the preparation, the water solubility, mechanical property and antimicrobial property were selected as indicators to test the films and evaluate the comprehensive performance of the films. When m(starch)∶m(gelatin)∶m(glycerin) was 6∶3∶1, the content of microcapsule was 20%, the content of CaCl2 was 2%, and the reaction temperature was 50 ℃, the film had relatively good comprehensive performance. The starch-based films incorporated with microcapsule showed good antimicrobial property. |
