中文摘要:
      以海藻酸钠为壁材制备牛至精油微胶囊,通过正交试验优化了微胶囊的最佳制备工艺条件,并对其进行了结构表征和抑菌效果研究。结果表明,制备牛至微胶囊的最佳工艺条件为:海藻酸钠质量分数2.5%、氯化钙质量分数1.5%、壁芯比为1∶1、乳化剂为0.2%的吐温-80和0.1%的单甘酯,在此条件下,微胶囊中牛至精油的包埋率为60.48%,其内部为多孔结构,且抑菌效果良好,当其用量达到0.02 g时,对灰霉的抑菌圈直径达到90 mm。
英文摘要:
      Oregano oil microcapsule was prepared by utilizing sodium alginate as wall materials. The technology of preparing oregano oil microcapsule was optimized by orthogonal experiment design, and its structural characterization and antimicrobial activity were also tested. The results showed that oregano oil microcapsule shows the best quality when the concentration of sodium alginate, calcium chloride, Tween-80 and monoglycerides were 2.5%, 1.5 %,0.2% and 0.1% respectively, and the ratio between wall and core materials was 1∶1. The embedding rate was 60.48% under the condition. There are vesicular structures in the internal of the prepared oregano oil microcapsule, which showed obvious antimicrobial activity, and the inhibition zone diameter of Botrytis cinerea arrived at 90 millimeters when the addition amount of oregano oil microcapsule achieved 0.02 gram.
