毛葱油微胶囊制备工艺的研究

Research on preparation of microcapsule of Alliums cepa.L.var.agrogatum Don essential oil

以石油醚提取的毛葱油为芯材,选用β-环糊精为壁材对其进行包埋。以包埋率为测定指标,以芯壁比、搅拌时间、搅拌温度为研究因素,通过响应面软件优化确定毛葱油微胶囊制备的最佳工艺流程为芯壁比1∶5.6、搅拌时间2 h、搅拌温度45℃。在此条件下得到毛葱油微胶囊包埋率为41.56%。

Take Alliums cepa. L. var. agrogatum Don （ACAD） essential oil as core material and β - cy-clodextrin （β- CD） as wall material, the oil was embedded with β -CD. The optimal technologicalprocess to prepare the microcapsule of ACAD essential oil was optimized by response surface methodolo-gy, with embedding rate as the index and the ratio of core to wall, mixing time and mixing temperature asthe factors. The results showed that under the optimized condition （ the ratio of core to wall was 1 ： 5.6,mixing time 2 h and mixing temperature 45 ℃ ）, the embedding rate of the microcapsule was 41.56%.
