摘　　要：为探究枳椇子和余甘子提取物共包埋微胶囊喷雾干燥工艺,改善它们的加工和贮藏特性,采用层次分析-指标相关性赋权系数法(AHP-CRITIC)确定指标权重系数(黄酮包埋率、多酚包埋率、黄酮载药量、多酚载药量),建立微胶囊综合评分体系,采用响应面法优化微胶囊的制备工艺,同时对制备得到的微胶囊颗粒理化特征、结构表征进行综合分析。结果表明,喷雾干燥法制备提取物微胶囊的最佳工艺条件为:芯壁质量比2∶3.5,进风温度162.5℃,壁材配比(麦芽糊精和阿拉伯胶质量比)为1∶1.39,在此条件下的微胶囊综合评分为67.498,颗粒大小均匀,结构完整,粒径为3.833μm。微胶囊性能研究表明,麦芽糊精+阿拉伯胶作为复合壁材能很好地包埋枳椇子和余甘子提取物,提高其热稳定性、防潮性以及贮藏稳定性。In order to optimize the process of Hovenia dulcis-Phyllanthus emblica extract co-encapsulated microcapsules and improve the processing and storage characteristics of Hovenia dulcis-Phyllanthus emblica extract,the microcapsule was maded by spray drying method.Taking flavonoid embedding rate,polyphenol embedding rate,flavonoid drug loading and polyphenol drug loading as investigation indexes,the analytic hierarchy process-criteria importance though intercrieria correlation(AHP-CRITIC)method was used to determine the weight coefficients of each index and establish a comprehensive scoring system for microcapsules.Response surface methodology was used to optimize the preparation conditions of microcapsules.The physicochemical properties and structural characterization of microcapsules were analyzed.The results showed that the optimum conditions for the preparation of extract microcapsules by spray drying method of core-wall ratio,inlet-air temperature and wall material mass ratio(maltodextrin and gum arabic)were 2∶3.5,162.5℃and 1∶1.39,respectively.Under this condition,the microcapsules had uniform particle size and complete structure,with a particle size of about 3.833μm and a comprehensive score of 67.498.The study on microcapsule performance showed that the wall material composition of maltodextrin and gum arabic could be a good co-encapsulate on the Hovenia dulcis-Phyllanthus emblica extractive,and improve the heat stability,moisture resistance and storage stability of the extractive.
