响应面法优化玉米叶酸提取工艺的研究 Title:OptimizationofFolicAcidExtractionProcessfromCornLeavesusingResponseSurfaceMethodology Abstract: Folicacid,akeymicronutrientwithnumeroushealthbenefits,canbeextractedfromvarioussources,includingcornleaves.Inthisstudy,responsesurfacemethodology(RSM)wasemployedtooptimizetheextractionprocessoffolicacidfromcornleaves.Theaimwastomaximizetheyieldoffolicacidwhileminimizingtheconsumptionofresources.Athree-levelBox-Behnkendesign(BBD)wasusedtosystematicallyinvestigatetheeffectsofthreeindependentvariables,namelyextractiontime,extractiontemperature,andsolvent-to-solidratio,onthefolicacidyield.Theoptimizedconditionsweredeterminedusingamathematicalmodel,andthefolicacidyieldobtainedwascomparedwiththeinitialconditions.
