Crude oils contain non-triacylglycerol components that must be partially or totally removed in order to become acceptable for human consumption. Crude oils are therefore submitted to several treatments, the objective being to remove the objectionable minor components with the least possible damage to the oil fraction and minimal losses of desirable constituents. There are two major processing methods known as chemical and physical refining. Palm oil is by far the most important fractionated oil in the world; crude, semi- and fully refined palm oil can be fractionated in multi-stage, giving access to several products for specific applications. Identically, palm kernel oil is a popular feedstock for the formulation of Cocoa Butter Substitutes (CBS) after fractionation and full hydrogenation. Recent developments in continuous dry fractionation have shown serious advantages when applied on palm oil.
