摘　　要：测定了核桃油脂肪酸和维生素E成分,并将β-环糊精、黄原胶/麦芽糊精组合分别作为壁材,采用包埋络和工艺以及喷雾干燥工艺包埋核桃油,比较两种微胶囊工艺的包埋效果。结果表明,在核桃油中,单不饱和脂肪酸含量为20.74%,多不饱和脂肪酸含量为70.278%,不饱和脂肪酸高达90%以上,维生素E含量为3.11 mg/mL;包埋效果以黄原胶/麦芽糊精壁材进行喷雾干燥后得到微胶囊效果较好,包埋率(95.28%)高于以β-环糊精为壁材采用包埋络和工艺的包埋率(83.23%)。The experiment detected the fatty acid and VE composition of walnut oil and the embedded effect of microencapsulating parietal layer of β-cyclodextrin,xanthan/maltodextrin through different technology had been detected.The results showed that monounsaturated fatty acids in walnut oil were 20.74％,the polyunsaturated fatty acids were 70.278％,the unsaturated fatty acids reached as high as 90％,and the content of VE was 3.11 mg/mL The embedded effect of xanthan/maltodextrin parietal layer was 95.28％,which was higher than β-cyclodextrin parietal layer （83.23％）.
