Title:TheImpactofModerateProcessingTechniquesontheQualityofRiceBranOil
Abstract:
Ricebranoil,extractedfromtheouterlayerofricekernels,isapopularcookingoilduetoitsimpressivenutritionalprofileandpotentialhealthbenefits.Theaimofthispaperistoexploretheimpactofmoderateprocessingtechniquesonthequalityofricebranoil.Variousstagesinvolvedintheprocessingofricebranoil,suchasdebranning,stabilization,extraction,andrefining,arediscussedindetail.Itfurtherdelvesintotheeffectsofmoderateprocessingtechniquesonthephysical,chemical,andsensorypropertiesofricebranoil.Thepaperconcludesbyemphasizingtheimportanceofimplementingappropriateprocessingtechniquestoensuretheproductionofhigh-qualityricebranoil.
