Abstract
To prevent or decrease colour fixation in cottonseed oil containing high level of phospholipids (4%), it was treated before or after fixation with chemical and physical treatments using ethanolamine, degumming or sodium silicate. Treatment of cottonseed oil with ethanolamine at 4% of the oil before or after fixation results in refined and bleached oils darker than the untreated oil. Carrying out degumming before fixation followed with ethanolamine at 1% only of the oil improved the oil colour. Treatment of cottonseed oil with sodium silicate at 1% of the oil before fixation results in superior refined and bleached oils than the untreated oils.
