摘　　要：以萝卜红色素为原料,比较系统地探讨了超临界状态下萃取压力、温度、时间对萝卜红色素精制的影响。结果表明,萃取压力30 MPa、萃取时间150 min和萃取温度55℃可以达到精制萝卜红色素的效果。The influence of extracting pressure, temperature, time on the refinement of red radish pigment was studied systematically under supercritical condition. The results showed that 30MPa, 150min and 55℃ was suitable to obtain purified microparticulated red radish pigment.
