Many different processes exist for the extraction of oil products. Amongst them, the heating/separation process or the use of, in some cases, alcoholic based solvents to ‘cut’ the oil from the seed. These methods although a cheaper alternative, rely on adding to the product other non-beneficial constituents. This form of ‘dilution’, results in harming the quality and more importantly the beneficial properties of their products. At Iman, We add nothing so nothing is taken away.
