  • 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°C, at which time 300¨C1000 ppm of phosphoric acid is injected into the oil and mixed vigorously.
  • How is canola processed?
  • With respect to processing, both canola types are generally processed similarly in the crushing, extraction, and refining processes. Some of the most important parameters affecting canola processing begin before the seed arrives at the plant for crushing and extraction.
  • What is canola crushing?
  • Canola crushing is an important part of the overall canola industry in Canada. The production and processing include classic canola and canola containing high oleic canola oils. With respect to processing, both canola types are generally processed similarly in the crushing, extraction, and refining processes.
  • What species of canola is produced in Western Canada?
  • Greater than 99% of the canola produced in Western Canada is of the Brassica napus species (Canadian Grain Commission, 2009). Some of the most important parameters affecting canola processing begin before the seed arrives at the plant for crushing and extraction.
  • Why is canola oil extraction so bad?
  • This inhibits the release of oil during the pressing stage, will make solvent penetration into the canola cell structure very difficult, and will not allow for the leaching of oil bodies from the canola seed particles. This results in very poor extraction efficiency and poor process economics.
  • 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.
