Solvent Extraction

There are numerous plants, oil seeds, nuts, blossoms that contain too little volatile oil to be exposed to expression method of extraction. Moreover, their ingredient components are too fragile to sustain the high levels of heat of steam distillation. The high degrees of steam act as flames of fire and cause the natural ingredients to get denatured early and easily. As a result, the plant nutrients get evaporated leaving the major waste chunk.

It is through the 'Solvent Extraction' method that such natural oils can be safely extracted. The most preferred element used here is Hexane.
