Palm oil is derived from the fruit of oil palm tree, which is grown in tropical regions of Asia and Africa. Saturated fatty acid and unsaturated fatty acid account for about 50% respectively, which endow the palm oil with better oxidative stability than other vegetable oils. Therefore, it is more suitable for frying and cooking. Currently, the palm oil is a kind of vegetable oil with the largest production, consumption and international trade volume in the world. After refining and fractionating, we can get the palm oils with different melting points, which have wide applications in the catering industry, food industry and oil and chemical industry.
Palm Oil Fractionation is the special treatment for palm oil. Lowering the palm oil temperature to about 24 ℃ for a definite period of time, the ingredients with a high melting point will be crystallized and separated out. After secondary filtration, the palm oil can be fractionated into three products with different melting points, which are palm stearin (melting point>40℃), palm palmitin (melting point about 30℃) and liquid palm oil (melting point<20℃). And the liquid palm oil quality can reach the standard of high-level edible oil.
Palm oil fractionation process:
The fractionation methods of palm oil are composed of dry fractionation, solvent fractionation, and surfactant fractionation.
1. Dry fractionation
Palm oil→heating→cooling and crystallizing→filtering→palmitin, stearin
2. Solvent fractionation
Palm oil→solvent diluting→cooling and crystallizing→separating→solvent evaporating→palmitin, stearin
3. Surfactantfractionation
Palm oil→cooling and crystallizing→water soluble surfactant solution adding→stearic crystal wetting→centrifugal separating→washing→drying→palmitin, stearin
