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.
Introduction:
Folicacid,alsoknownasvitaminB9,playsacrucialroleinthesynthesisandrepairofDNA,aswellasincelldivisionandgrowth.Itisespeciallyimportantforwomenofchildbearingage,asitisessentialforproperfetaldevelopment.Cornleaves,abyproductofcorncultivation,havebeenidentifiedasapotentialsourceoffolicacid.Efficientextractionoffolicacidfromcornleavesisofgreatsignificanceforthedevelopmentoffunctionalfoodproductsandnutraceuticals.However,thetraditionalextractionmethodsofteninvolvelengthyextractiontimes,highsolventconsumption,andlowyield.Therefore,itisnecessarytooptimizetheextractionprocesstoenhancetheefficiencyandyieldoffolicacidextraction.
