油茶籽油中富含不饱和脂肪酸和多种活性物质,为了增强其氧化稳定性,用麦芽糊精和大豆分离蛋白为壁材将其微胶囊化。在单因素试验的基础上,采用正交试验对油茶籽油微胶囊制备工艺进行优化,结果显示:在乳化剂添加量为1.4%、壁材比为1∶1(g/g)、芯壁比为3∶5(g/g)条件下制得的微胶囊成品为洁白细腻的粉末,其水分含量为3.13%、堆积密度为0.42 g/cm~3、表面含油量为1.95%、平均粒径为13.5μm,散落性、溶解性及感官评定结果良好。红外光谱结果显示芯材与壁材之间并未发生化学反应,包埋效果较理想。热重分析结果表明油茶籽油在微胶囊化后稳定性增加;扫描电镜结果显示微胶囊成品呈球形和椭球形,表面结构...

Camellia seed oil is rich in unsaturated fatty acids and active substances. In order to enhance its oxidative stability, maltodextrin and soy protein isolate were used as wall materials to encapsulate camellia seed oil. On the basis of single-factor experiment, the preparation process of camellia seed oil microcapsules was optimized by orthogonal experiment, and optimal conditions were as follows: emulsifier addition amount 1.4 %, the wall-material ratio 1 ∶ 1(g/g), and the core wall ratio 3 ∶ 5(g/g). The finished microcapsules was white and ...
