摘　　要：以明胶和CMC(羧甲基纤维素)为壁材,采用复凝聚法制备黄酮类化合物微胶囊。通过单因素和正交试验确定影响制备黄酮类化合物微胶囊主要因素,经实验确定最优工艺条件为:壁材浓度1.5%、明胶∶CMC为8∶1、芯壁比1∶5、复凝聚pH值4.6、复凝聚温度40℃;在此条件下,黄酮类化合物微胶囊平均包埋率可达78.2%。Microcapsules containing flavonoids compounds were prepared by complex coacervation method with gelatin and sodium carboxy methyl cellulose as shell materials. By single factor and orthogonal experiment, research the gelatin/CMC proportion, core wall temperature, pH, than other factors on the influence of microcapsule preparation, their morphological characteristics and the encapsulation efficiency of the microcapsules were inspected, preparation technology was optimized. The best technological conditions： wall material concentration 1.5%, gelatin/CMC proportion 8 ： 1, core/wall material ratio 1 ： 5, pH 4.6, reaction temperature 40 ℃, under these conditions, encapsulation efficiency can amount to 78.2%.
