Main Steps of palm oil refining process:

1.Degumming.
In this step gums in crude oil are removed by hydration with the help of phosphoric acid. Degumming is the first step for the whole palm oil refinery process.
2. Neutralization. 
In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.Neutralization is also called deacidification, it is the important part for palm oil refinery.
3. Bleaching.
During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer. Bleaching is also decolorization in palm oil refinery.
4. Deodorization.
Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.  Deodorization is mainly for making oil color lighter during palm oil refinery process. Which can make oil looks good.
5. Fractionation.
Palm oil wll be two status under a certain tempreature, solid and liquid. We call the solid palm stearin, and liquid is palm olein.
Fractionation is mainly for separating palm olein and palm stearin.  In the supermarket, all the oil is palm olein.  Palm stearin can be as deep-processing products.
