3 OIL EXTRACTION TECHNOLOGIES 3.1 Aqueous enzymatic extraction Aqueous extraction is a traditional technique that uses water as a solvent to extract oil from oleaginous materials. Because water takes long to degrade the cell wall of oil-bearing mate-rial, the process is less effective and results in low yield. To

Oil can be directly extracted with solvent from products which are low in oil content, that is, soybean, ricebran and corn germ. After sterilization, oil-bearing fruits are pulped (digested) before mechanical pressing often in a screw press. Palm kernels are removed from pressed cakes and further processed for oil.

Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents.

Extraction of oil from oil-bearing seeds consists mainly of four major steps: Pre-treatment of the raw material: During this step the oil-bearing seeds are cleaned, dried, and de-hulled. Then clean seeds are weighted and passed to a de-stoner and a magnet to remove stones and metals, then prepared for oil extraction and cooking.
