Refined Oils

How refined oil processed?

The process of extracting vegetable oil from oil seeds is not for the squeamish.

  1. Oil seeds such as soybean, rapeseed, cotton, sunflower are gathered. Most of these seeds are from plants that have been genetically engineered to resist the huge amounts of pesticides applied to them.
  2. The seeds are husked and cleaned of dirt and dust, then crushed.
  3. The crushed seeds are then heated to temperatures between 110 degrees and 180 degrees in a steam bath to start the oil extraction process.
  4. The seeds are put through a high volume press which uses high heat and friction to press the oil from the seed pulp.
  5. The seed pulp and oil are then put through a hexane solvent bath and steamed again to squeeze out more oil.
