Canola refers to both an edible oil (canola oil) and a type of Brassicaceae plant.
The plant is a cultivar of Brassica napus, Brassica rapa, or Brassica juncea. They are well known for their seeds, from which the canola cooking oil is made The oil is widely used for preparing food, it is also good for people's health because it has very little saturated fat and a lot of polyunsaturated fats.
Besides cooking, there are also other ways to use canola oil. One of these is to produce biodiesel fuel for cars and trucks.
Canola oil is a vegetable oil derived from a variety of rapeseed that is low in erucic acid, as opposed to colza oil. There are both edible and industrial forms produced from the seed of any of several cultivars of the plant family Brassicaceae.
According to the Canola Council of Canada, an industry association, the official definition of canola is "Seeds of the genus Brassica (Brassica napus, Brassica rapa, or Brassica juncea) from which the oil shall contain less than 2% erucic acid in its fatty acid profile and the solid component shall contain less than 30 micromoles of anyone or any mixture of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy- 4-pentenyl glucosinolate per gram of air-dry, oil-free solid."Canola oil is also used as a source of biodiesel.
The name for rapeseed comes from the Latin word rapum meaning turnip. Turnip, rutabaga (swede), cabbage, Brussels sprouts, and mustard are related to rapeseed. Rapeseed belongs to the genus Brassica. Brassica oilseed varieties are some of the oldest plants cultivated by humanity, with documentation of its use in India 4,000 years ago, and use in China and Japan 2,000 years ago Its use in Northern Europe for oil lamps is documented to the 13th century.
Rapeseed oil extracts were first put on the market in 1956–1957 as food products, but these suffered from several unacceptable characteristics. Rapeseed oil had a distinctive taste and a disagreeable greenish color, due to the presence of chlorophyll. It also contained a high concentration of erucic acid.
Canola was bred from rapeseed cultivars of B. napus and B. rapa at the University of Manitoba, Canada, by Keith Downey and Baldur R. Stefansson in the early 1970s, having then a different nutritional profile than present-day oil in addition to much less erucic acid. Canola was originally a trademark name of the Rapeseed Association of Canada, and the name was a condensation of "Can" from Canada and "OLA " meaning "Oil, low acid", but is now a generic term for edible varieties of rapeseed oil in North America and Australasia. The change in name serves to distinguish it from natural rapeseed oil, which has much higher erucic acid content.
A genetically engineered rapeseed that is tolerant to herbicide was first introduced to Canada in 1995 (Roundup Ready canola). A genetically modified variety developed in 1998 is considered to be the most disease- and drought-resistant canola variety to date. In 2009, 90% of the Canadian crop was herbicide-tolerant. In 2005, 87% of the canola grown in the US was genetically modified In 2011, out of the 31 million hectares of canola grown worldwide, 8.2 million (26%) were genetically modified
A 2010 study conducted in North Dakota found glyphosate- or glufosinate-resistance transgenes in 80% of wild natural rapeseed plants, and a few plants that were resistant to both herbicides.
This may reduce the effectiveness of the herbicide tolerance trait for weed control over time, as the weed species could also become tolerant to the herbicide. However, one of the researchers agrees that "feral populations could have become established after trucks carrying cultivated GM seeds spilled some of their load during transportation". She also notes that the GM canola results they found may have been biased as they only sampled along roadsides.
Genetically modified canola attracts a price penalty compared to non-GM canola; in Western Australia, it is estimated to be 7.2% on average.
