摘 要：
以阿拉伯胶和麦芽糊精为壁材,对喷雾干燥法制备余甘子核仁油微胶囊的工艺进行研究。通过单因素试验和响应面优化试验考察乳化剂添加量、阿拉伯胶与麦芽糊精质量比、芯壁比及固形物添加量对余甘子核仁油微胶囊包埋率的影响,得到最优微胶囊制备条件为乳化剂添加量1%、阿拉伯胶与麦芽糊精质量比1∶3.4、芯壁比2∶3、固形物添加量14.2%,该工艺条件下得到的余甘子核仁油微胶囊的包埋率达到(90.74±0.51)%,包埋效果好,颗粒形态完整。采用油脂氧化稳定性测定仪(Rancimat法)测定该样品的氧化诱导时间,并对微胶囊在25℃条件下的货架期进行预测发现,微胶囊的货架期为716 d,未包埋的余甘子核仁油货架期为128 d,由此可见该微胶囊具有良好的贮藏稳定性。

摘 要：
A study of the microencapsulation process of Phyllanthus emblica L.(P. emblica L.) seed oil was carried out by the spray-drying method using gum acacia and maltodextrin as wall materials. The effects of emulsifier concentration, gum acacia/maltodextrin ratio, core/wall ratio and solid concentration on microencapsulation efficiency were investigated. As a result, The optimum conditions were obtained as follows: emulsifier concentration 1%, gum acacia/maltodextrin ratio 1:3.4(m/m), core/wall proportion, 2:3(m/m), and solid concentration, 14.2%. The highest microencapsulation efficiency obtained in this study was(90.74 ± 0.51)%. The scanning electron microscopy(SEM) images indicated that the microcapsules obtained under the optimum conditions were completely spherical and smooth. The oxidative stability of free and microencapsulated oils were tested under accelerated oxidative conditions by the Rancimat method. The results showed that the microencapsulated oil stored at 25 ℃ had a longer shelf-life(716 days) than the free oil(128 days). Thus microcapsules can apparently enhance the storage stability of P. emblica L. seed oil.
