Cottonseed miscella was treated with FeCl3 to form an iron-gossypol complex. The treated miscella was then extracted with alkaline water. The supernatant lipid filtered through bleaching clay produced an oil containing virtually no light-absorbing color bodies and a product that compared favorably, colorwise, with commercial oil.
