Palm Oil Fractionation Process

Palm oil is semisolid at ordinary temperatures of 20º to 27ºC because of the precipitation of saturated glycerides. These glycerides have relatively high melting points and possess only a limited solubility in the unsaturated glycerides. Fractionation was carried out for the separation of high-melting triglycerides from low-melting triglycerides by crystallization when they melt.
The purification steps of the crude palm oil sample such as filtration, degumming, neutralization and bleaching was carried out to ensure the removal of non-glycerides impurities which also affect the fractionation process. By the method of fractional crystallization after complete treatment of Crude Palm Oil (CPO), Filtered, Degummed, Neutralized and Bleached Palm Olein (FDNB Palm Olein) was produced. In this process, liquid olein was produced as the main product and solid stearin as by-product. Separation of liquid (olein) and solid (stearin) was carried out by centrifugation. Plate-and-frame filtration method (Yashino System) was also attempted. To control the process and quality of the product, analysis of oil was carried out after every stage of processing from CPO. In this study, second fractionation of palm oil at 25ºC gave the favorable conditions in which the iodine value of super olein was raised to 65.35 and refractive index of those was also increased to 1.4655.
