Huile de Colza is the French term for "Rapeseed Oil" which is also known in the United States as Canola Oil. Rapeseed oil is of vegetable origin and is obtained from crushed rapeseed by pressing or extraction. It is a light yellow to brownish yellow oil. Rapeseed oil is one of the most important vegetable oils. For centuries, humans and animals could not consume rapeseed oil, as it had a high erucic acid content. However, rapeseed varieties are now available for cultivation which have a lower erucic acid content. Rapeseed oil is used as an edible oil, a machine oil and in the production of margarine and soap. It may also serve as a substitute for diesel fuel (biodiesel). English: Rapeseed oil, rape oil German: Rapsöl, Rüböl French: Huile de colza (navette) Spanish: Aceite de colza (nabina) Scientific: Brassica napus
