摘要
目的:优化紫甘蓝色素提取工艺,测定色素的抗氧化能力。方法:以紫甘蓝为原料,在单因素实验基础上,利用正交设计超声波辅助优化紫甘蓝色素的最佳提取工艺条件,利用DPPH法来检测其抗氧化能力。结果:超声波辅助紫甘蓝色素最佳提取工艺条件是:浸提液pH为1,液固比为25:1(mL,g),温度在50℃,时间为50min,清除DPPH·能力,最高可达95%。结论:利用最佳工艺提取到色素,色素具有良好的抗氧化能力。
Objective：It was to research optimization of extraction technology for purple cabbage pigment and antioxidant activity.Method：On the condition of single factor experiment,the ultrasonic-assisted extraction technology was optimized with orthogonal experiment design,and antioxidant activity was investigated by scavenging capacity DPPH·.Result：The optimal extraction technology for purple cabbage pigment was ratio 25：1（mL,g）,pH 1,50 min and 50℃,scavenging capacity to DPPH· could be up to 95%.Conclusion：The optimal extraction technology suit to extract pigment from purple cabbage,and the pigment has strong antioxidant ability.
