Canola oil, or canola for short, is a vegetable oil derived from rapeseed that is low in erucic acid, as opposed to colza oil.Canola oil is made at a processing facility by slightly heating and then crushing the seed. Almost all commercial canola oil is then extracted using hexane solvent[21] which is recovered at the end of processing. Finally, the canola oil is refined using water precipitation and organic acid to remove gums and free fatty acids, filtering to remove color, and deodorizing using steam distillation. The average density of canola oil is 0.92 g/ml.
