The journey from field to bottle involves cleaning, crushing, heating, and chemical extraction, followed by refining, bleaching, and deodorizing to create a product with a high smoke point and long shelf life. 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.

Flaking breaks the seed cell walls to improve oil flow. At the plant, the seeds undergo rigorous cleaning to remove debris, stones, and dockage using sieves and air classifiers.
Cooking denatures enzymes and reduces oil viscosity. 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.

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. This mechanical pressing typically recovers about 60 to 70 percent of the oil.
