What is "colza oil"

n. edible light yellow to brown oil from rapeseed used also as a lubricant or illuminant [syn: rape oil, rapeseed oil]

Colza oil or Rapeseed oil is a nondrying oil obtained from the seeds of Rapeseed (Brassica napus subsp. napus. syn. Brassica napus var. oleifera Delile, Brassica campestris subsp. napus (L.) Hook.f. & T.Anderson.) Colza is extensively cultivated in France, Belgium, the United States, the Netherlands, Germany and Poland. In France, especially, the extraction of the oil is an important industry. In commerce, colza is a traditional rapeseed oil (with turnip rape oil, sarson oil, toria oil ( Brassica rapa ssp.), and ravison oil), to which they are very closely allied in both source and properties. It is a comparatively nonodoriferous oil of a yellow colour, having a specific gravity varying between 0.912 and 0.920. The cake left after extraction of the oil is a valuable feed ingredient for pigs.
