These flowers eventually develop into small pods, each containing two tiny seeds that hold approximately 40% oil by weight. This journey begins in vast North American farmlands, where canola plants are cultivated specifically for their oil-rich seeds.
Steps to Prepare Canola Seeds for Extraction
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. Farmers plant seeds in early spring, and by mid-summer, the fields are covered in vibrant yellow blossoms.
The Initial Cleaning and Preparation Process Before any extraction can occur, the harvested seeds undergo rigorous cleaning to remove debris, chaff, and damaged 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.
Steps to Prepare Canola Seeds for Extraction
The extracted oil mixture undergoes multiple filtration and purification stages to remove impurities, free fatty acids, and unwanted compounds. Refining processes may include degumming, neutralization, and bleaching, which collectively remove phosphatides, pigments, and other materials that could affect flavor, stability, and appearance.
