What is canola seed preconditioning process?
In this process, canola seed is pressed a second time to extract oil without using solvents. Up to that point, the preconditioning process may be the same as for traditional processing. The resulting meal has higher oil content, and therefore provides more energy.
How to extract canola oil?
Canola Oil Pressing There are mainly two methods for extracting Canola oil, one is Mechanical Press and second is Solvent Extraction. In Mechanical Press, Canola oilseeds are pressed in a series of Screw Presses / Expellers. This process uses no chemical and leaves about 5-7% oil in the residual Cake/Meal.
How is canola seed processed?
The process for turning canola seed into oil and meal is similar to how other oilseeds are processed. Seed is preconditioned and pressed to separate the oil from the solids. Further refining and processing create finished canola products, ready for the market or further processing. Most Canadian companies use the same method to process canola seed.
