摘要:以羟丙基-β-环糊精(HP-β-CD)为壁材,牛至精油为芯材,通过饱和水溶液法制备牛至精油-HP-β-CD微胶囊,与涂料复合涂布制备抗菌食品包装纸。结果表明,微胶囊的最佳制备工艺为包合时间3 h、包合温度50 ℃、芯壁比1∶8。在此工艺条件下制备的牛至精油-HP-β-CD微胶囊的芯材包合率为83.69%,具有良好的缓释效果,微胶囊及其制备的抗菌食品包装纸对金黄色葡萄球菌和大肠杆菌具有良好的抑菌性能。
Abstract:Antibacterial food packaging paper was coated with the composite coating including oregano essential oil-hydroxypropyl-β-cyclodextrin microcapsules that prepared via saturated aqueous solution method using hydroxypropyl-β-cyclodextrin as wall material and oregano essential oil as core material. The results showed that the inclusion rate of oregano essential oil was 83.69% with an excellent sustained release effect at the optimum preparation conditions of microcapsule with inclusion time of 3 h, inclusion temperature at 50 ℃ and the ratio of core material and wall material of 1∶8. In addition, both microcapsules and the prepared antibacterial food packaging paper had outstanding antibacterial properties against Staphylococcus aureus and Escherichia coli.
