| 摘 要： | 利用真空浓缩与喷雾干燥法制备爬山虎色素粉末干品，以色素粉末的含水量、溶解速率及其水溶液的溶解性和吸湿性为检验指标，采用正交设计探索真空浓缩与喷雾干燥技术制备爬山虎红色素粉末的最佳工艺参数。结果表明，真空浓缩的最佳工艺参数为用旋转蒸发仪将滤液在(40 ± 1)℃、旋转速度(40 ± 2)r/min 的条件下真空浓缩30min。喷雾干燥最佳工艺参数为在加入待喷液质量分数2% 的可溶性淀粉后调整其可溶性固形物含量达到10%～13%、进料速度3mL/min、进口风温度175～180℃、出口风温度60～70℃、排风量0.35～0.37m3/min、雾化压力100kPa，此条件下制备爬山虎红色素粉末能很好的解决喷雾干燥过程中的粘壁问题，同时色素粉末质量完全符合预期设计。

| Abstract: | Parthenocissus tricuspidata red pigment powder was prepared through sequential steps of extraction with aqueous acid solution, vacuum concentration and spray drying. In the present study, the vacuum concentration process was optimized using orthogonal array design for obtaining maximum pigment concentration, and subsequently the optimal spray-drying process was investigated using uniform design for reaching a good compromise moisture among content, dissolving rate, water dissolubility and moisture absorptio... |
