摘　　要：以沙田柚白果皮为原料,研究脉冲电场辅助提取柚皮苷的工艺,以期为柚子产业副产物的综合利用提供技术支持。在单因素实验的基础上,以乙醇浓度、脉冲数和电场强度作为优化因素,柚皮苷提取量为响应值,通过Box-Behnken响应面设计确定了脉冲电场提取白果皮中柚皮苷的最优工艺:脉冲数29次、乙醇浓度43%、电场强度4 kV/cm,柚皮苷提取量高达16.79 mg/mL,浸提效果好、选择性高,脉冲电场能提高柚皮苷的抗氧化活性。In order to provide technical support for the comprehensive utilization of by-products of grapefruit industry,the technology of extracting naringin by pulse electric field was studied.On the basis of single factor experiment,the concentration of ethanol,the number of pulses and the intensity of electric field were taken as the optimization factors,and the amount of naringin extraction was taken as the response value.The optimal process of extracting naringin from pomelo peel was determined by the Box-Behnken response surface design.With 29 pulses,43%ethanol concentration,4 kV/cm electric field intensity,16.79 mg/mL naringin extraction amount was obtained,the extraction effect is good and the selectivity is high.Pulse electric field can improve the antioxidant activity of naringin.
