Commercial palm oil refining usually includes deacidification, decolorization and deodorization. Palm fractionation is also an important part of palm refining. Fractionation mainly divides palm oil into stearin and soft fat.
Palm olein, also known as palm ointment, is the main product in the palm refining process. The palm fraction uses low temperature crystallization to change the liquid palm stearin into a solid state. Palm olein remains in a liquid state. The crystallized palm oil is filtered to separate liquid and solid fractions.
Palm stearin is the solid fraction obtained during the fractionation of palm. It is often mixed with other edible oils to achieve the desired function. For example, margarine fat, shortening, hydrogenated vegetable oil, etc. In addition, palm stearin is also commonly used in industrial production, such as soap and animal feed.
The refining process of palm oil is more complicated than that of other vegetable oils. If you are interested in palm oil refining, you can contact us for more information.
