以盐地碱蓬为原料,利用超声波辅助提取盐地碱蓬红色素。通过单因素和正交试验研究了超声波功率、液固比、提取温度及提取时间等因素对盐地碱蓬红色素提取效果的影响,确定了超声波辅助提取盐地碱蓬红色素的工艺条件。结果表明:各因素对盐地碱蓬红色素提取效果的影响程度依次为液固比>提取温度>超声波功率>提取时间;适宜提取工艺条件为,提取时间50 min,提取温度50℃,液固比(mg∶L)15∶1,超声波功率800W。

Suaeda salsa were taken as raw materials and the ultrasonic-assisted extraction technology was used to extract red pigment from Suaeda salsa.The single factor and orthogonal experiments were adopted to study the effects of such factors as ultrasonic power,liquid-solid ratio,time and temperature on extraction of red pigment.The optimal technological condition of red pigment extraction from suaeda salsa by ultrasonic was determined.The order of factors that influence the extraction of red pigments was as follows;liquid-solid ratio>extraction temperature>ultrasonic power>extraction time.The optimal extraction parameters were as follows;extraction time 50min,extraction temperature 50℃,liquid-solid ratio 15 mL/g,ultrasonic power 800W.In addition,ultrasonic improved the pigment extraction in this experiment.
