The bleaching process is a crucial process in palm oil refining in which an adsorbent is majorly used to adsorb the unwanted colour pigments and a wide range of other impurities. Groundnut hull was collected and processed into powder form as Groundnut hull powder [GHP], the powder was used to remove the colour pigments and other minor impurities from crude palm oil. Free fatty acid (FFA) analysis was carried out on the palm oil before and after bleaching. The effects of three factors: temperatures, mass and time were investigated on the response. Central Composite Design [CCD] employed resulted in 20 runs. The conducted analysis has shown that groundnut hull was able to reduce FFA composition as well as reduce the colour of the palm oil to a desired colour.
