Effect of refining processes on antioxidant capacity, total contents of phenolics and carotenoids in palm oils

► The impact of refining process on antioxidant capacity of palm oils was evaluated. ► Antioxidant capacity of palm oils was determined by FRAP and DPPH methods. ► The crude palm oils are rich in hydrophilic and lipophilic antioxidants. ► Antioxidants content in palm oils correlated with their antioxidant capacity. ► The refining process decreased antioxidant capacity of palm oils.
