摘要:为提高天然植物香精的封装保护稳定性和应用效果，本研究以明胶（GE）和纤维素纳米晶（CNC）为壁材、以玫瑰香精为芯材，通过复凝聚法制备了包埋玫瑰香精的GE/CNC复合微胶囊，并以微胶囊粒径和玫瑰香精包埋率为指标，对制备条件进行了优化，探究其缓释性能、储存稳定性和释放动力学。结果表明，GE/CNC复合微胶囊的最优制备条件为：壁材总质量分数2.0%、壁材比6∶1、芯壁比1∶2，该条件下所制GE/CNC复合微胶囊的粒径为1~2 μm，呈光滑球形，玫瑰香精最大包埋率为81.5%，且热稳定性良好。与纯GE微胶囊相比，GE/CNC复合微胶囊的pH稳定性和温度稳定性有所提升；在4和25 ℃下分别储存24天后，其玫瑰香精释放率分别为63.28%和66.57%，表现出良好的缓释性能，该释放过程符合一级动力学模型。
Abstract:In order to improve the encapsulation stability and application effect of natural plant essences, GE/CNC composite microcapsules embedded rose essence were prepared by complex coacervation method, using gelatin (GE) and cellulose nanocrystals (CNC) as wall materials and rose essence as core material. The preparation conditions were optimized with the particle size of microcapsules and the embedding rate of rose essence as indexes, and the sustained release performance, storage stability, and release kinetics were investigated. The results showed that the optimal preparation conditions of GE/CNC composite microcapsules were as follows: the total wall material mass fraction was 2.0%, the wall material ratio was 6∶1, and the core-wall ratio was 1∶2. The particle size of the GE/CNC composite microcapsules prepared under optimal conditions was 1~2 μm with smooth spherical in shape, and the maximum encapsulation rate of rose essence was 81.5%, exhibiting good thermal stability. Compared with pure GE microcapsules, the pH stability and temperature stability of GE/CNC composite microcapsules were improved. After 24 days of storage at 4 and 25 ℃, the release rate of rose essence was 63.28% and 66.57%, respectively, showing good sustained release performance. The release process conformed to the first-order kinetic model.
