IMAGE 1- Rapeseed
Rapeseed is a bright-yellow flowering member of the family Brassicaceae, cultivated mainly for its oil-rich seed, the third-largest source of vegetable oil in the world.
Rapeseed oil was produced in the 19th century as a source of a lubricant for steam engines, because it was less useful as food for animals or humans because it has a bitter taste due to high levels of glucosinolates. Varieties have now been bred to reduce the content of glucosinolates, yielding a more palatable oil. This has had the side effect that the oil contains much less erucic acid.
