Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient. Sunflower oil is primarily composed of linoleic acid, a polyunsaturated fat, and oleic acid, a monounsaturated fat. Through selective breeding and manufacturing processes, oils of differing proportions of the fatty acids are produced.
What is high oleic sunflower oil?
High oleic sunflower contains 4?times more oleic acid than classical sunflower, with 84% oleic acid in oil. It competes on global scale with other high oleic oils but has the highest oleic level compared to oleic safflower (78%), oleic rapeseed and canola (75¨C73%) and oleic soybean (73%) ( Tonin, 2018 ).
How is crude sunflower oil degummed?
For the physical refining process, crude sunflower oil was degummed using the TOP degumming method. In this process, the oil was treated with 0.3% w/w phosphoric acid (75% w/w), and the H3PO4 was neutralized with 0.15% w/w sodium hydroxide (40% w/w).
Are there different types of sunflower oil seeds?
Several varieties of sunflower oil seeds have been developed by standard plant breeding methods, mainly to vary the amounts of oleic acid and linoleic acid which, respectively, are the predominant monounsaturated and polyunsaturated fats in sunflower oil. Sunflower oil is a rich source of vitamin E (tables).
