超声波辅助提取南瓜色素的工艺研究

On the Technique of Ultrasonic wave-assisted Way to Extract Pumpkin Pigments

通过单因素试验和正交试验,考察超声波提取南瓜色素的工艺参数和提取效果,实验结果表明超声波提取南瓜色素的最佳工艺条件为:提取温度70℃,料液比25:1,超声时间35 min,超声功率300 W。

By a single factor synthesis and an orthogonal test, this paper examines the technical parameters and effects of ultrasonic wave-assisted way to extract pumpkin pigments. The experimental result demonstrates the best technical conditions of extracting pumpkin pigments by ultrasonic-wave-assisted way as follows： extracting temperature at 70℃, mass-liquid ratio at 25 ： 1, ultrasonic-waved time at 35 minutes, and ultrasonic wave power capacity at 300 W.
