One of the most wrongly perceived process about palm oil is Fractionation. Most of the time it is perceived as a chemically induced method to obtain various palm based products but it is not. Fractionation is the process used to separate the lower melting point triglycerides from the higher melting point triglycerides. The process is based on the difference of melting points of the various triglycerides and involves crystallization which helps separate the solids from liquids. There are essentially three types of fractionation which involves the gradual lowering of temperature to induce crystallization and hence separation of higher melting point triglycerides ( solid component – called stearin ) from the lower melting point triglycerides ( liquid component – called olein ).
