摘　　要：为探究淀粉基复配壁材对番茄红素微胶囊缓释性能的影响,喷雾干燥制备了3种番茄红素微胶囊,并测定了微胶囊的理化指标和结构,最后研究了3种微胶囊的缓释性能。结果表明酯化微孔淀粉复配壁材的包埋率最好,红外光谱及热重分析说明形成了包埋结构并具有良好的热稳定性;扫描电镜表征表明微胶囊形成表面光滑的球形;最后微胶囊的模拟释放试验表明在模拟肠液中释放符合Higuchi扩散模型。因此酯化微孔淀粉是一种可用于微胶囊化的壁材。In order to investigate the effect of different starch composite wall materials on the sustained-release performance of lycopene microcapsules,three kinds of lycopene microcapsules were prepared by spray drying,respectively.The physical and chemical indexes and structures of the three kinds of microcapsules were determined.Finally,the sustained-release performance of microcapsule was also studied.The results show that the microencapsulation efficiency of esterified microporous composite starch wall material was the best.Fourier infrared spectroscopy and thermogravimetric analysis showed that the encapsulation structure was formed and has good thermal stability.Scanning electron microscopy showed that the microcapsule was formed into a smooth surface sphere.Finally,the simulated sustained-release test of the microcapsules shows that the release in the intestinal fluid conforms to Higuchi diffusion model.Therefore,esterified microporous starch is a kind of wall material for microencapsulation.
