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%。
The effects of different emulsifiers on oil -tea camellia seed oil microcapsule powder were stud- ied.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.
