Oil extraction Practical Action Some seeds (especially groundnuts for example) are conditioned by heating to 80-90oC using a seed scorcher (Figure 2 shows a typical small-scale example – a separate heat source is necessary beneath the scorcher). All oil-bearing materials need to have the correct moisture content to maximise the oil yield.

Oil is the main component of the seed and represents 36.7% of the seed weight. The oil can be extracted almost entirely by solvent extraction, generally n-hexane, whereas less yield is obtained by cold press extraction. In fact, only 69% (on average) of the total oil contained in seeds can be extracted by cold press [21–23].
