"The Rapeseed plant has been grown for thousands of years for camp oil and cooking oil, and in the 1940's was employed as a lubricant for steam locomotives and ship engines (soon being replaced by diesel fuel). In addition, this semi-drying oil is used as a fuel, soap base, synthetic rubber base, and illuminant for slick, magazine-style, color pages. A member of the mustard family, Rape oil, according to some sources, is also used to produce the chemical warfare agent "Mustard Gas," as well as the more benign homeopathic remedy "Thiosinaminum." Canadian farmers were initially introduced to it as an oil crop in 1942, but not until 1957 was an edible form of its oil first extracted. However, its versatility was limited as a commercial crop due to some inherently negative characteristics. It contained high amounts of two undesirable substances: ERUCIC ACID, which can be harmful to humans, and GLUCOSINOLATES, which have the damaging effect of inhibiting livestock growth. But scientists will be scientists, and eventually breeders were successful in developing varieties low in both of these compounds. In 1974, researchers at the University of Manitoba, Winnipeg utilized genetic engineering techniques to alter its chemical composition, making Canola more suitable for consumption.
"In 1988, the U.S. Food and Drug Administration permitted the coined name "Canola" to be used as a generic name for "lear oil," resulting in a significant increase in its importation into this country. Today, we purchase in excess of 80% of Canada's total production of edible vegetable oils, 63% of which is Canola. As a matter of public record, the Canadian government and industry paid our (FDA) $50 million dollars to have Canola oil placed on the GRAS ("Generally Recognized As Safe") list, part of a scheme to sidestep the otherwise lengthy and much more expensive approval process." -janet allen
