Canola oil obtained from pressing canola seeds and oil rapeseeds. Both canola seeds and rapeseeds belong to the exactly same Brassica genus; however, the name Canola (Canadian oilseed- low acid) coined for modified plant developed by Canadian scientists. The scientists applied traditional plant breeding methods to get rid of rapeseed’s undesirable qualities – erucic acid and glucosinolates. Both rapeseed and canola plants are, therefore, belongs to the same genus of the crucifer family called Brassica; the large family of plants which also includes turnip, mustard, Brussels sprouts, cabbage, kale, cauliflower, broccoli, etc.
Canada, USA and the European Union are chief produces rapeseeds. In general, edible oil pressed from seeds of rapeseed plant referred by different names as canola oil, rapeseed 00 oil, low erucic acid rapeseed oil, LEAR oil, and rapeseed canola-equivalent oil…etc. Present day edible rapeseed oil is limited by government regulations to a maximum of 2% erucic acid by weight in the USA and 5% in the EU.
Physical characteristics of canola oil
Canola oil is light yellow and has a neutral taste of brassica plants. In general, canola seeds pressed either employing traditional cold-pressing methods or in large scale, by hexane extraction method. Color, taste, and odor of cold-pressed oil indeed more pronounced than that of refined oil.
Its specific gravity @25°C is 0.916-0.921. Iodine value-110–120; and saponification values-188-198.
Canola adds billions to Canada’s economy
A study released in 2017 shows Canadian-grown canola contributes $26.7 billion to the Canadian economy each year, including more than 250,000 Canadian jobs and $11.2 billion in wages.
Demand for canola continues to grow as the world learns more about its advantages for human health and as a source of high-quality feed and biofuel feedstock.
That’s why it’s so important to maintain responsible public policies that nurture the growth of this industry.
Canada’s most valuable crop
Canola generates one quarter of all farm cash receipts. Acreage continues to increase because of the profitability and resilience of the crop. Newer herbicide-tolerant varieties produce higher yields at a lower cost and with less potential risk to the environment.
43,000 farmer decision-makers grow canola, mostly in the western provinces of Alberta, Saskatchewan and Manitoba. British Columbia, Ontario and Quebec also grow a substantial amount of the crop. New varieties are pushing the boundaries of where canola is grown.
Canada Canola industry
Canada exports 90% of its canola as seed, oil or meal to 50 markets around the world, bringing billions of dollars into Canada. The biggest buyer of canola oil and meal is the United States, accounting for about 65% of oil exports and 82% of meal exports in 2016. For raw seed, the most important destinations are China, Japan and Mexico.
