The processes are hydrogenation, interesterification and fractionation. Hydrogenation is a process of addition of hydrogen to a fat to obtain different degrees of hardness. The process is done in the presence of a nickel as a catalyst. The temperature used between 100oC and 200oC and at 15 atmospheres of pressure. The purpose of the hydrogenation is to increase the stability of oil’s solid fat content by reducing the level of unsaturation in oils. Hydrogenation processing conditions can be modified in order to create a range of fats and oils with different characteristics such as melting point of the oils (Henry,2009 ; McWilliams,
