The present invention relates to a process for extracting minor components in palm oil. The minor components are known as phytonutrients. The minor components are such as carotenes, tocols, tocopherols and tocotrienols, sterols, squalene, coenzyme Q, phospholipids and glycolipids. The process for extracting includes the steps of: i) mixing the palm oil with alcohol and catalyst, (ii) heating the mixture obtained from step (i) using microwave with frequencies between 200MHz to 300GHz; (iii) cooling the mixture 10 obtained from step (ii) to room temperature; (iv) adding non-polar solvent into the mixture obtained from step (iii) and the mixture is agitated wherein a top layer and bottom layer are formed; (v) subjecting the bottom layer to agitation with non-polar solvent; (vi) repeating step (v) on the bottom layer formed in step (v) and subsequent bottom layers that are formed by adding non-polar solvent and followed by agitation until the upper layer turns pale yellow in color; (vii) drying the upper layers obtained from step (iv), (v) and (vi). |
