Throughout these stages, the oil is carefully monitored to meet strict food safety standards and regulatory requirements for commercial食用油 production. Solvent Extraction: The Modern Extraction Method While traditional methods used mechanical pressing alone, modern canola oil production primarily employs solvent extraction to achieve higher yields.

Final Processing and Quality Assurance Before reaching store shelves, refined canola oil often undergoes a final deodorization process that removes volatile compounds responsible for any remaining odors or flavors. The crushed flakes are washed with food-grade hexane, a highly effective solvent that dissolves the oil compounds while leaving behind the solid protein-rich residue known as canola meal.
This crushing process reduces the seeds into small, flattened pieces called "flakes," which dramatically increases the surface area available for oil extraction. Farmers plant seeds in early spring, and by mid-summer, the fields are covered in vibrant yellow blossoms.
Optimizing Moisture Levels for Healthy Canola Seeds
The Critical Crushing Stage The heart of canola oil production begins with mechanical crushing, where the prepared seeds are pressed to break open the protective seed coat and release the oil trapped within. The final product on your supermarket shelf represents years of agricultural science, engineering innovation, and strict quality control measures designed to deliver a consistent, high-quality ingredient.
