摘　　要：通过L9（34）正交试验确定花生衣红色素的最佳提取工艺,同时对其稳定性进行研究。结果表明：色素最佳提取工艺条件为：提取剂50%乙醇,浸提温度40℃,浸提时间80min,料液比1∶25（g/mL）。花生衣红色素的特征吸收峰为495nm;该色素对pH、温度、光照、以及VC、K＋、Na＋、Ca2＋、Mg2＋、Cu2＋、Na2SO3稳定性较好,对柠檬酸、H2O2、Fe3＋稳定性较差。The extraction technology of pigment from Peanut-skin was optimized by L9（34）orthogonal test,and the stability of the pigment was studied in this paper.The results showed：Pigment optimal extraction conditions were that extraction agent is 50% ethanol,extraction temperature is 40℃,extraction time is 60 min,solidliquid ratio is 1：25.Peanut-skin red pigment of the characteristic absorption peak is 495 nm;this pigment has good stability for pH,temperature,light,and the VC、K＋、Na＋、Ca2＋、Mg2＋、Cu2＋、Na2SO3,has less stability for citric acid,H2O2 and Fe3＋ etc.
