Hexane is the most common solvent used in rice bran oil extraction . This solvent is cheap and efficient, but it is a petroleum-based solvent, volatile, flammable, and dangerous for humans and for the environment . Several efforts have recently been made to find alternatives to this organic compound, focusing on green, non-petroleum-derived, and bio-based solvents.

If by pressing method, it will waste 6-7% oil at least, so the best way of extracting rice bran oil is solvent extraction method. The residual oil ratio of solvent extraction method is less than 1%, so to get more oil from oil seeds, most oil seeds with low oil content less than 20% use the solvent extraction plant.

Rice bran contains 16 to 22% oil and this oil is recovered by solvent extraction process. Rice bran being floury material it is essential to palletize the bran before being put to solvent extraction process. The solvent extraction of palletized rice bran is carried out in normal way.
