Refined sunflower oil process

Refined sunflower oil process, Sunflower oil is one of the large oil source in northern China. Rich in linoleic acid and oleic acid, higher nutritional value, but a waxy crude oil and containing traces of oxygen acids, affect the quality and storage stability. Commercially available crude sunflower oil refining and refined edible oil two kinds of grades.
