中文摘要: 运用多指标综合评分法优化高压脉冲电场提取橘皮总黄酮和色素的工艺。选取乙醇浓度、液料比、电场强度和脉冲数为考察因素，在单因素试验的基础上，采用综合评分法进行响应面试验。根据回归方程优化并得到最佳提取工艺为乙醇浓度60%、液料比31∶1（mL/g）、电场强度17 kV/cm、脉冲数12个，综合评分达到90.86。
Abstract:A comprehensive scoring method was used to optimize the technology of high-voltage pulsed electric field extracting flavones and pigments of orange peel.Single factor and Box-Behnken tests were used to optimize the extraction technology，with ethanol concentration，liquid-to-material ratio，electric field intensity and pulse number as factors.The optimized conditions of the extraction technology based on the regression equation were as follows:ethanol concentration of 60%，liquid-to-material ratio of 31∶1 （mL/g），electric field intensity of 17 kV/cm and 12 pulses.Under these conditions，the comprehensive score reached 90.86.
