摘  要:
以辣椒红色素为芯材,变性淀粉和明胶为壁材,糊精为填充剂,研究微胶囊化辣椒红色素的制备工艺。通过实验,确定出影响微胶囊化效果的各因素为:变性淀粉与明胶比例为2:1,辣椒红色素含量为40%,乳液固形物含量为45%。通过L9(34)正交试验对微胶囊化喷雾干燥工艺进行优化,在出风温度80℃条件下,确定最佳的喷雾条件为进风温度180℃、进料量20.0ml/min、气流压力0.15MPa。

摘  要:
Microcapsules of paprika oleoresin were prepared by spray-drying technology using paprika oleoresin as the core material, modified starch and gelatin as the wall materials, dextrin as the filler.Results indicated the optimal microencapsulation conditions were 2:1 of modified starch to gelatin ratio, 40% of paprika oleoresin content, and 45% of emulsion solid content.Moreover, the optimal conditions for spray-drying were also investigated through orthogonal array design experiments, which were 180 ℃ for inlet temperature, 80-90 ℃ for outlet temperature, 20.0 ml/min for flux rate and 0.15 MPa for inlet air pressure.
