| 中文摘要: |
| 为拓宽三丁酸甘油酯的应用范围，以三丁酸甘油酯为芯材，抗性糊精-明胶-海藻酸钠（RGS）、抗性糊精-明胶-海藻酸钠-月桂酸单甘酯（RGSG）、抗性糊精-明胶-壳聚糖（RGC）、抗性糊精-明胶-壳聚糖-月桂酸单甘酯（RGCG）为壁材，采用喷雾干燥法制备4种微胶囊，对微胶囊包埋率及产率、粒径分布、基本理化性质、颜色、结构特征及外观形貌进行分析，探究不同壁材对三丁酸甘油酯微胶囊性质的影响。结果表明：RGSG微胶囊包埋率（91.05%）及产率（90.46%）较高；与RGC、RGS微胶囊相比，RGSG、RGCG微胶囊的水分活度、粒径分布、流动性、吸湿性、亮度均有一定的改善；红外光谱及扫描电镜结果表明三丁酸甘油酯被壁材有效包埋起来，其中RGSG、RGCG微胶囊形成了更强的氢键。综上，RGSG制备的微胶囊综合性质优于其他3种壁材。 |

| In order to broaden the application range of tributyrin, using tributyrin as the core material, and resistant dextrin-gelatin-sodium alginate(RGS), resistant dextrin-gelatin-sodium alginate-glycerol monolaurate(RGSG), resistant dextrin-gelatin-chitosan(RGC), resistant dextrin-gelatin-chitosan-glycerol monolaurate(RGCG) as wall materials, four kinds of microcapsules were prepared by spray drying method. Tributyrin microcapsules were evaluated with regard to embedding rate and yield, particle-size distribution, basic physicochemical properties, color, structural characteristics and appearance. The results showed that RGSG as the wall material had higher embedding rate (91.05%) and yield (90.46%). Compared with RGS and RGC microcapsules, RGSG and RGCG microcapsules had better water activity, particle-size distribution, fluidity, hygroscopicity and brightness. Fourier transform infrared spectroscopy and scanning electron microscope revealed that tributyrin were effectively encapsulated. RGSG，RGCG as the wall materials formed more intense hydrogen bonds. In conclusion, the comprehensive properties of tributyrin microcapsules prepared with RGSG as wall material were better than those of the other three kinds of wall materials. |
