摘要
本文采用喷雾干燥法制备高纯α-亚麻酸为芯材、亚麻籽胶为壁材的微胶囊,并以微胶囊化效率和含油率为指标,考察了制备工艺。结果表明,最佳微胶囊原料配方为:芯材与壁材的比例为(m/m)3∶2,料液浓度为5%,进料温度为20℃;最佳喷雾干燥工艺条件:进风温度为180℃,出风温度为80℃,雾化器转速21000 rpm,进料速度为42.01 mL/min。在此工艺条件下亚麻酸的微胶囊化效率为96.18%,含油率为60.09%。
The microencapsulation of high-purity α-linolenic acid was prepared with the spray drying method using high-purity α-linolenic acid as core material and flaxseed gum as wall material.The acting factors of preparing high-purity α-linolenic acid microcapsule have been investigated in detail according to microencapsulation efficiency and the ratio of oil content.The results showed that the best material compositions for microencapsulation were as follows:core material/wall material(m/m) 3∶ 2,material concentration(mass-volume percentage,core material plus wall materials to mixed solution) 5%,and feeding temperature 20 ℃;the optimal spray drying processing conditions were determined as follows,the air temperature at the inlet was 180 ℃,while at the exit was 80 ℃,the rotating speed of centrifugal atomizer was 21000 rpm,and liquid feed rate was 42.01 mL/min.The content of microencapsulation efficiency was 96.18% and the ratio of oil content was 60.09%.
