At the plant, the seeds undergo rigorous cleaning to remove debris, stones, and dockage using sieves and air classifiers. Mechanical Pressing and Solvent Extraction After flaking, the material is cooked to reduce viscosity and then sent through a series of screw presses or hydraulic presses to extract a portion of the oil.
Hexane Safety Standards in Canola Oil Extraction
Deodorization and Winterization Perhaps the most critical step in refining is deodorization, where the oil is heated under a vacuum to strip volatile compounds that cause strong odors. From Seed to Crude Oil: The Extraction Process The production of canola oil starts on the farm, where canola seeds are harvested and transported to a processing facility.
Processing Stage Key Purpose Impact on Oil Quality Degumming Remove phospholipids Improves stability and appearance Neutralization Remove free fatty acids Reduces acidity and bitterness Bleaching Remove pigments and impurities Creates light color and bland flavor Deodorization Remove volatile odors Provides neutral cooking profile Winterization Remove waxes Prevents cloudiness in cold temperatures. These seeds contain roughly 40 percent oil, which is extracted through a multi-stage industrial process that transforms raw material into a neutral cooking oil found in kitchens worldwide.
Hexane Safety Standards in Canola Oil Extraction
The remaining oil trapped in the press cake is then extracted using hexane, a petroleum-based solvent that dissolves the residual oil without damaging the protein structure. This mechanical pressing typically recovers about 60 to 70 percent of the oil.
