中文摘要: 香荚兰浸膏的挥发性及稳定性等问题影响其在食品、化妆品等领域的应用。试验采用搅拌法、研磨法和喷雾干燥法制备香荚兰浸膏/羟丙基-β-环糊精（hydroxypropyl-β-cyclodextrin，HP-β-CD）包合物，以感官、得率及包合率为指标筛选最佳制备方法，采用红外光谱法（infrared spectroscopy，IS）对包合物进行表征，对包合物的粒径、微观结构及溶解特性进行研究。结果表明：最佳制备香荚兰浸膏包合物的方法为喷雾干燥法，其得率为62.53%，浸膏中油脂包合率为98.03%。通过IR的表征及扫描电镜分析，证明包合物已形成；喷雾干燥法下50%以下包合物粒径为8.74 μm，溶解特性分析得到包合物溶解度远高于香荚兰浸膏溶解度，通过高效液相色谱法对香兰素的增溶试验分析得到，30%的HP-β-CD水溶液可以增加浸膏中香兰素33%的溶解度。
Abstract:The volatility and stability of vanilla concentrate affect its application in food and cosmetics.In this experiment，the vanilla concentrate/hydroxypropyl-β -cyclodextrin inclusion compound was prepared by stirring，grinding and spray drying methods.The best preparation method was selected by taking sensory，yield and inclusion rate as indicators.The inclusion compound was characterized by infrared spectroscopy Infrared spectroscopy，and the particle size，microstructure and dissolution characteristics of the inclusion compound were studied.The results showed that the best method for the preparation of vanilla concentrate was spray drying，the yield was 62.53%，and the highest oil inclusion rate was 98.03%.Through IR characterization and sem analysis showed that the inclusion compound was formed.Under the spray drying method，the particle size of inclusion compound below 50%was 8.74 μm，and the solubility of the inclusion compound was much higher than that of vanilla concentratet.The solubility of vanillin was obtained by HPLC，and the solubility of vanillin could be increased 33%with 30%hp-β-cd aqueous solution.
