Rapeseed

Rapeseed (pronounced /ˈreɪpsiːd/), also known as rape, oilseed rape, and, in the case of one particular group of cultivars, canola, is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family), cultivated mainly for its oil-rich seed. It is the third-largest source of vegetable oil and second-largest source of protein meal in the world.

Etymology

The term "rapeseed" comes from the Latin rapum meaning turnip. Turnips, rutabaga, cabbage, Brussels sprouts, mustard, and many other vegetables are related to the two natural canola varieties commonly grown, which are cultivars of Brassica napus and Brassica rapa. The change in name serves to distinguish it from natural rapeseed oil, which has much higher erucic acid content.
