Sunflower oil, whether refined or unrefined, undergoes specific processing steps to ensure its quality and suitability for consumption. Unrefined sunflower oil, after purification, retains its distinct aroma, rich taste, and dark-yellow color. Refined sunflower oil undergoes thorough purification to eliminate impurities and maintain a light color, neutral taste, and odorlessness, making it suitable for cooking and other culinary uses. The refining process involves treatment with alkali to remove free fatty acids and phospholipids, followed by bleaching to separate any remaining impurities.
