• Does canola oil need to be refined?
  • This canola oil can proceed directly to bleaching in a process that is referred to as ¡°physical refining.¡± Once-refined oils also do not require further alkali refining. In traditional alkali refining, the crude degummed oil is heated to 50¨C60¡ãC, at which time 300¨C1000 ppm of phosphoric acid is injected into the oil and mixed vigorously.
  • How is canola oil produced?
  • Canola oil is refined using water precipitation and organic acid to remove gums and free fatty acids. It is then filtered to remove color and deodorized using steam distillation. Cold-pressed and expeller-pressed canola oil are also produced on a more limited basis.
  • How is canola oil deodorized?
  • Deodorization of canola oil is very similar to other oils such as soybean, corn, cottonseed, and sunflower oil. When the physical refining process is used, the bleached oil fed to the deodorizer will contain up to 1% free fatty acids, whereas most alkali-refined oils contain less than 0.2¨C0.3% free fatty acids.
  • Is canola a good oil?
  • Canola (rapeseed) is the world’s third-largest oilseed crop, trailing behind only soybean and cottonseed. It contains a smaller amount of non-polymerizing saturated fatty acids, which means it has superior edible characteristics. Further, it contains 6¨C14% ¦Á-linolenic acid, 50¨C65% oleic acid, and 7% saturated fatty acids.
  • Does canola oil contain oleic acid?
  • Canola oil is composed of 6%¨C14% ¦Á-linolenic acid, 50%¨C65% oleic acid, and < 7% of saturated fatty acids (Ghazani & Marangoni, 2013; Gunstone, 2011). However, cold pressed canola oil contains a comparatively higher content of tocopherols (60¨C70 mg/100 g) and phytosterols.
  • Which provinces produce the most canola?
  • The provinces of Saskatchewan and Alberta in Canada account for around 20 percent of global canola production. Rapeseed oil has been used for thousands of years in ancient civilizations in Europe and Asia. But it had high amounts of erucic acid ¨C a fatty acid that can be toxic to humans in large doses.
