摘　　要：为提升藜麦副产物的利用价值及拓展天然色素来源,本实验以藜麦壳为原料,借助响应面法对藜麦壳色素的超声波辅助提取工艺进行优化。结果表明:在色素提取影响因素中,超声温度影响最显著;优化后工艺为:乙醇浓度91.5%,超声温度、时间和功率分别为35℃、20 min、300 W,在该条件下,色素的吸光度值达0.736±0.001,这表明超声辅助提取是一种藜麦壳色素简单有效的方法。In order to improve the utilization value of quinoa by-products and expand the source of natural pigments, this experiment used quinoa husk as raw material, and optimized the ultrasonic-assisted extraction process of quinoa husk pigment by response surface method.The results showed that ultrasonic temperature had the most significant effect among four factors affecting pigment extraction;The optimal process was: ethanol concentration 91.5%,ultrasonic temperature 35 ℃,ultrasonic time 20 min, and ultrasonic power 300 W.Under these conditions, the absorbance value of the pigment was 0.736±0.001,which indicated that the ultrasound-assisted extraction was a simple and effective method for quinoa husk pigment.
