摘要
以阿拉伯胶和麦芽糊精为壁材,以无花果的乙醇提取物为芯材,用喷雾干燥法制取无花果微胶囊粉。通过正交试验分析,确定了最佳生产工艺条件:芯材与壁材的比例为1:4,阿拉伯胶与麦芽糊精的比例为1:1,固形物浓度为30%,乳化剂用量为0.3%,30 MPa均质2遍,进风温度为200℃,出风温度为81℃。生产出的微胶囊无花果粉色泽、溶解性好,水、表面油含量低,无甚粘壁现象,适合于工业化生产。
With arabic gum and maltodextrin as wall material, fig ethanol extracts as core material, the fig microencapsulation powder was produced by spray drying. Through orthogonal experiment, the optimum technological conditions was determined as follows: the ratio of core material and wall material was 1:4, the ratio of arabic gum and maltodextrin 1 : 1, the concentration of solid content 30%, emulsifier addition 0.3%, homogenized at 30 MPa twice, inlet air temperature 200 ~C and outlet air temperature 81 qC. The acquired product is well in color and solubility, low in water and surface oil content, seldom wall sticking, suitable for industrial production.
