What students need to know about REFINING OF PALM KERNEL OIL

This work studied the refining of crude palm kernel oil derived from the kernels within the nut of a palm fruit.
This research project was aimed at reducing the non-glycerides present in oil in their crude form using an alkali method of refining.  The crude palm kernel oil was first washed with distilled water by heating the mixture in an electric heater for about 2 hours to reduce  the  impurities  present  in  the  oil  in  their  crude  form, degummed  with  phosphoric  acid  and  neutralized  with  NaOH (caustic  soda).The  saponification  value,  iodine  value  and  acid value was analyzed and their values are: for crude palm kernel oil, 33.1, 695.45 and 746.13 respectively, for neutralized palm kernel oil, 11.22, 725.6 and 687.24 respectively
