以玉米油为基料油，通过添加 3 种不同的凝胶剂(谷甾醇 + 卵磷脂，神经酰胺和乙基纤维素)，制备了荷载姜黄素的三元油脂凝胶体系，并探讨了不同凝胶剂对三元油脂凝胶的流变行为、固体脂肪含量等宏观性质及其微观形貌、晶型结构等微观性质以及荷载量的影响． 实验结果表明，谷甾醇 + 卵磷脂与神经酰胺形成的三元凝胶结构相似，都形成纤维状的结晶结构;前者的结构更为紧密，荷载量［(3． 14 ± 0． 10)mg/g］和包埋率［(62． 78 ±2． 01)%］较高;乙基纤维素形成的凝胶结构与前两种有很大不同，其结晶结构为颗粒状，晶体较小，结构较为松散，但是由于其较高的制备温度，它的荷载水平最佳，荷载量和包埋率分别为(4． 810 ±0． 174)mg/g 和(96． 19 ±3． 48)%． 这说明油脂凝胶剂的种类对三元油脂凝胶的性能、微观结构和荷载量都有显著影响．

Ternary curcumin-organogels were prepared based on corn oil and by using sitosterol + letithin,cera- mide,ethyecellulose as thestructurants.Then,the effects of the structurants on the macroscopic properties (the rheological behaviors,the solid fat content,etc) and the microscopic properties (the microstructures,the crys- talline structure,etc) of ternary organogels were discussed,and the corresponding loading capacities were also evaluated.Experimental results show that (1) the structures of sitosterol + letithin-organogels and ceramide- organogels are similar and are both fibrous crystal structure,and the former exhibits a tighter network with higher encapsulation efficiency (EE) and loading capacity (LC),which are respectively (3. 14 ± 0. 10) mg/g and (62. 78 ±2. 01)%; (2) however,the structure of ethyecellulose-organogelsis totally different from the above two structures,and it is granular with a smaller crystal and relatively loose network; and (3) because of higher prepa- ration temperature.ethyecellulose-organogels show the highest load level,specifically,LC and EE are respectively (4. 810 ±0. 174)mg/g and (96. 19 ±3. 48)%. The above results indicate that the structurants significantly affect the properties,microstructures and loading capacity of organogels.
