| 研究基于复合壁材的薏米糠油微胶囊制备工艺，以包埋率为响应值，在单因素试验基础上，采用响应面法优化喷雾干燥制备薏米糠油微胶囊的工艺，并分析了微胶囊的热稳定性和玻璃化转变温度（Tg）。结果表明：以阿拉伯胶（AG）和麦芽糊精（MD）为复合壁材，在壁材配比（AG与MD质量比）1∶?1.3、芯壁质量比1∶?3.2、固形物含量31%、乳化分散15 min、30 MPa均质2次、进风温度180?℃的条件下，薏米糠油微胶囊包埋率为87.09%；热重分析表明薏米糠油微胶囊的热稳定性良好，差示量热扫描分析其Tg为35.1?℃。 |

| Preparation of adlay bran oil microcapsule based on compound wall materials was studied. With embedding rate as response value, the preparation process of adlay bran oil microcapsule by spray drying was optimized by response surface methodology based on single factor experiment, and the thermostability and glass transition temperature(Tg) of adlay bran oil microcapsule were analyzed. The results showed that with Arabic gum (AG) and maltodextrin (MD) as compound wall materials, under the conditions of mass ratio of AG to MD 1∶?1.3, mass ratio of core material to wall material 1∶?3.2, solid content 31%, emulsion dispersion 15 min, homogeneous twice at 30 MPa and air inlet temperature 180?℃, the embedding rate of adlay bran oil microcapsule was 87.09%.Thermogravimetric analysis revealed that the thermostability of the adlay bran oil microcapsule was good, and its Tg was 35.1?℃ according to the differential calorimeter scanning analysis. |
