摘　　要：以β-环糊精为壁材,采用饱和水溶液法制备香根油微胶囊,并进行正交优化。通过显微镜、扫描电镜、红外光谱等方法对微胶囊进行表征,确定了包合物的形成。研究表明香根油微胶囊制备的最佳工艺条件为:β-环糊精与香根油的质量比为8∶1,包埋时间为2 h,包埋温度为45℃。各因素对包埋率的影响程度从大到小的顺序为:包埋温度、β-环糊精与香根油的质量比、包埋时间。在最佳工艺条件下,香根油微胶囊的包埋率为62.82%,包合物产率为55.92%,综合评分为62.30。The microcapsule of vetiver oil is prepared by saturated aqueous solution method with β-Cyclodextrin as wall material. The orthogonal design is performed. The microcapsules are characterized by scanning electron microscopy,scanning electron microscopy and infrared spectroscopy. The optimal preparation conditions are shown as follows： 8∶ 1 of the mass ratio of β-cyclodextrin and vetiver oil,2 hours of embedding time and 45 ℃ of embedding temperature. The effect sequences of three main factors for embedding rate are： the embedding temperature〉 the mass ratio of β-cyclodextrin and vetiver oil〉 embedding time. Under the optimal conditions,the embedding ratio of the microcapsule of vetiver oil is 62. 82%. The yield is 55. 92% and the comprehensive score is 62. 30.
