| 中文摘要: |
| 研究了乳化剂对微胶囊化粉末油茶籽油的影响。结果表明，在壁材为阿拉伯胶和麦芽糊精（质量比1∶?3），以大豆卵磷脂和吐温-80（6∶?4）的复配乳化剂乳化油茶籽油形成的乳液具有较好的乳液稳定性，且喷雾干燥制备的微胶囊粉末油茶籽油颗粒均匀、细腻、干燥。经扫描电镜观察，微胶囊粉末油茶籽油颗粒外形较圆整，大小分布较均匀，表面光滑，其载油量及包埋率分别为35.6%和82.02%。 |
| 英文摘要: |
| The effects of different emulsifiers on oil-tea camellia seed oil microcapsule powder were studied. The results showed that when using gum arabic - maltodextrin （mass ratio 1∶?3) as wall material, the prepared oil-tea camellia seed oil microcapsule powder had better emulsion stability with the complex emulsifier soybean lecithin and Tween-80 (6∶?4) and it was uniform and dry. The scanning electron microscopy results showed that the oil-tea camellia seed oil microcapsule powder had round shape, uniform size distribution, and smooth surface. The loading amount of oil- tea camellia seed oil and embedding rate were 35.6% and 82.02%, respectively. |
