摘　　要：以羧甲基纤维素(CMC)、阿拉伯胶和明胶为壁材,橘油为芯材,采用复合凝聚法制备球状多核橘油微胶囊。研究壁材比例、壁材浓度、芯壁比、pH值和搅拌速度对复合凝聚微胶囊形态和粒径的影响,并探讨CMC/阿拉伯胶/明胶复合凝聚橘油微胶囊的产率、载量和释放性质。结果表明,以CMC/阿拉伯胶/明胶为壁材,制备球状多核结构的复合凝聚橘油微胶囊的工艺条件是:mCMC/m阿拉伯胶/m明胶=1:9:20,壁材质量分数1%,芯壁比1:1,pH4.27,搅拌速度300 r/min。CMC/阿拉伯胶/明胶复合凝聚橘油微胶囊具有较高的产率和优良的缓释特性。The spherical multinuclear microcapsules containing orange oil were prepared by complex coacervation,using CMC,gum Arabic and gelatin as wall material.Effect of various processing parameters,including the CMC/gelatin/ gum Arabic ratio,wall material concentration,core/wall ratio,pH and stirring speed on the morphology and particle size of coacervate microcapsules was investigated.Yield,loading and release rate of coacervate microcapsules prepared by CMC/gum Arabic/gelatin were also discussed.The results showed that the optimal conditions for preparing CMC/gum Arabic/ gelatin spherical multinuclear microcapsules by complex coacervation were as follow：CMC/gum Arabic/gelatin of 1：9：20,wall material concentration of 1%,core/wall ratio of 1 ：1,pH 4.27 and stirring speed of 300 r/min.CMC/gum Arabic/ gelatin microcapsules by complex coacervation possessed high productivity and excellent slow-release characteristics.
