Sunflower oil is an oil pressed from the seeds of sunflower. Every year, tens of millions of tons of sunflower oil are consumed in the world, making this product extremely popular in the market.
This product seems to be very simple and familiar, however, it is widely used in food industry as a frying oil, and many dishes just cannot be prepared without it.
Refining of sunflower oil is carried out to improve the quality and form of the oil, to increase its shelf life. Refining sunflower oil through solvent extraction, de-gumming, neutralization, and bleaching can make it more stable and suitable for high-temperature cooking, but doing so will also remove some of the oil's nutrients, flavor, color (resulting in a pale-yellow), free fatty acids, phospholipids, polyphenols, and phytosterols.
Refined oil has practically no color, taste or smell, making it suitable for frying and other types of cooking, as its use does not affect the taste of the dish itself.
