摘要
研究了超声波辅助提取杜鹃花色素的最优工艺条件。以吸光度为考查指标,通过单因素和正交实验,得出超声波辅助提取杜鹃花色素的最优工艺条件为:乙醇体积浓度为70%,超声波功率为500 W,超声波时间为40min,液固比为20∶1,在此条件下测得杜鹃花色素母液的吸光度为0.6647。
Study on the optimum conditions for pigment from Rhododendron with ultrasonic-assisted extraction.The absorbance of liquid as criterion,optimization of process conditions with ultrasonic cooperated for pigment from Rhododendron were acquired with single factor and orthogonal test： ethanol concentration 70,ultrasonic power 500W,ultrasonic time 40 min,ratio of liquid to material 20 ∶ 1.The absorbance of liquid is 0.6647 under this conditions.
