摘要
采用超声辅助乙醇浸提法提取火龙果果皮红色素,考察乙醇浓度、料液比、提取时间、提取温度对火龙果果皮红色素提取率的影响。结果表明,各因素影响主次顺序为料液比>乙醇浓度>提取时间>提取温度,最佳工艺条件为:提取剂为30%乙醇,料液比1∶50(g/m L),超声时间30 min,提取温度40℃。采用此最佳工艺条件提取火龙果果皮色素提取率为0.071%。
The extraction of red pigment from pitaya peel by the way of ultrasound-assisted alcohol extraction method. The influence of ethanol concentration,liquid to material ratio,extraction time,extraction temperature on red pigment from pitaya peel was investigated. The result showed that the influence of various factors order is liquid to material ratio 〉 ethanol concentration 〉 extraction time 〉 extraction temperature（ B 〉 A 〉 C 〉 D）,and the best process conditions is when extract ethanol is 30%,liquid to material ratio is 1∶ 50（ g / m L）,ultrasonic time is 30 min,extraction temperature is 40 ℃. The extraction rate was0. 071% by using this best process conditions to extract red pigment from pitaya peel.
