According to the Canola Council of Canada, an industry association, the official definition of canola is "Seeds of the genus Brassica ("Brassica napus", "Brassica rapa", or "Brassica juncea") from which the oil shall contain less than 2% erucic acid in its fatty acid profile and the solid component shall contain less than 30 micromoles of any one or any mixture of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy- 4-pentenyl glucosinolate per gram of air-dry, oil-free solid." Canola oil is also used as a source of biodiesel.
