The present invention relates to a process to enhance the concentration of tocols from palm oil. More particularly, the present invention relates to a process to enhance the concentration of tocols from palm oil to at least more than 50%, preferably at least 70%, the process involves the steps of (a) reacting a low range tocotrienols rich fraction (TRF) with tocols content of 10-50% with an alcohol, a base and antioxidant in the dark at atmospheric pressure with temperature not more than 80°C, preferably 50-70°C, to form water soluble compounds, (b) adding a hydrophobic solvent to the mixture, (c) separating the water soluble compounds from the oil layer, (d) discarding the water soluble compounds from the oil layer, (e) rinsing tocols remained in the oil layer, (f) removing excess solvents from the tocols and (g) drying the tocols. |
