为减缓亚麻籽油中不饱和脂肪酸的氧化，该实验利用喷雾干燥技术，用大豆蛋白、麦芽糊精作为壁材，亚麻籽胶充当乳化剂，对亚麻籽油进行包裹，制备微胶囊，并对微胶囊产品进行理化指标的测定。结果表明：微胶囊产品含油率为38.03%，表面油含量为4.76%，包埋率达到87.50%，水分含量为1.30%，产品干燥，流动性好；颗粒分布均匀，基本呈球体；常温下溶解度良好；吸水性实验表明，产品易吸水，影响产品品质。

Inorder to slow down theoxidationof unsaturated fatty acid in flaxseedoil,flaxseedoil microcapsules were prepared by spray drying,with the mixtureof isolated soy protein and maltodextrin as wall materials and flaxseed gum as emulsifier. The physicochemical propertiesof the microcapsules were also studied. The results showed that the flaxseedoil microcapsules had totaloilcontentof 38.03%,surfaceoilcontentof 4.76%,encapsulation efficiencyof 87.50%,watercontentof 1.30%and presented good flowingcharacteristics. Particle analysis found that the sizesof microcapsules were equally distributed andclosed to sphere. The solubilityof the product was good at room temperature, and the moisture resistance experiment showed that product was easy to absorb water and deliquesced. So the product should be stored in the dry environment for a longer storage life.
