研究了微胶囊化过程中明胶的单凝聚,系统地考察了各种因素,如明胶浓度、油胶比、冷凝时间和固化时间等对微胶囊产率、包覆效率的影响,得到了微胶囊化的最佳条件;重点研究了不同凝冻速度的明胶对其微胶囊化过程的影响,证实了明胶的凝冻速度对其微胶囊化过程有重要影响,各种明胶都有自己适宜的冷凝时间;凝冻速度居中或偏慢的明胶更适宜于制备微胶囊,所得结果对选择微囊化所使用的明胶具有一定指导意义。 The effects of gelatin concentration, oil-to-rubber ratio, condensation time and curing time on the yield and coating efficiency of microcapsules were investigated systematically. The microcapsules The optimal conditions were studied. The effects of different gelation rates on the microencapsulation process were studied. The results showed that the gelation speed of gelatin had an important influence on the microencapsulation process. Gelatin had its own suitable condensation time. Gelatin with slow or slow freezing speed is more suitable for preparation of microcapsules. The obtained results are of guiding significance for the selection of gelatin used in microencapsulation.
