Introduction to Canola Oil
Canola oil is a vegetable oil that is extracted from the seeds of the canola plant, a member of the Brassica family. The canola plant is a cultivar of rapeseed, which is a bright-yellow flowering member of the family Brassicaceae, cultivated mainly for its oil-rich seed. The term “canola” was coined in the 1970s as a combination of “Canadian” and “ola,” which is a short form of the word “oil.” This name change was intended to distinguish the oil from rapeseed oil, which had a reputation for being unhealthy due to its high content of erucic acid.
History of Canola Oil
The origins of canola oil date back to the early 20th century, when Canadian farmers began growing rapeseed as a source of oil. Initially, the oil was used primarily for industrial purposes, such as in the production of soap and lubricants. However, with the discovery of the health risks associated with erucic acid, a naturally occurring toxin found in rapeseed oil, Canadian scientists and farmers set out to develop a safer alternative. Through a process of selective breeding, they created a variety of rapeseed that was low in erucic acid and had a more favorable fatty acid profile. This new variety was named canola, and its oil quickly gained popularity as a healthy and versatile cooking option.
