摘要: 在单因素试验的基础上,选取料液比、超声波功率、提取时间、提取温度为自变量,花青素含量为响应
值,采用响应面中心复合试验设计(CCD)方法优化了紫色马铃薯花青素超声波提取工艺. 结果表明:回归模型具
有高度显著性,回归方程对试验结果拟合较好,可用于花青素提取条件预测;最佳工艺条件为液料比28 ∶ 1、超声波
功率380 W、提取时间18min、提取温度47 ℃,在此条件下花青素提取率为602 mg/ kg.

Abstract: On the basis of single-factor test,the processing parameters,including solvent-material ratio,ultrasonic
power,extraction timeandtemperaturewereinvestigated.Theextractionrateofpurplepotatoanthocyaninwaschosenasre-
sponse value,and the ultrasonic-assisted extraction process for anthocyanin from purple potato was optimized by utilizing
central compositedesign (CCD)designandresponsesurfaceanalysis.Theresultindicatedthatthemodelwashighly signif-
icant,and the establishedregressionequationforpurplepotatoanthocyaninhadanexcellent goodnessoffit.Therefore,the
anthocyanin from purple potato could be analyzed and predicted by the model. The optimum technological conditions were
solvent-material ratioof28 ∶ 1,ultrasonicpowerof380W,extractiontimeof 18min,extractiontemperatureof47 ℃.Un-
