Sunflower oil is the non-volatile oil pressed from the seeds of the sunflower (Helianthus annuus). 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. The expressed oil has a neutral taste profile. The oil contains a large amount of vitamin E.
The Russian invasion of Ukraine that began in 2022 caused global prices of sunflower oil to increase by as much as 58% in a single month in 2022.
Composition
Sunflower oil is mainly triglycerides (fats), typically derived from the fatty acids linoleic acid and oleic acidSunflower oil is mainly a triglyceride.[5] The British Pharmacopoeia lists the following profile:[6][dubious – discuss]
Palmitic acid (saturated): 5%
Stearic acid (saturated): 6%
Oleic acid (monounsaturated omega-9): 30%
Linoleic acid (polyunsaturated omega-6): 59%
Four types of sunflower oils with differing concentrations of fatty acids are produced through plant breeding and industrial processing: high-linoleic (conventional), high-oleic, mid-oleic, and high-stearic combined with high-oleic.
High-linoleic, 69% linoleic acid
High-oleic, 82% oleic acid
Mid-oleic, 65% oleic acid
High-stearic with high-oleic, 18% stearic acid and 72% oleic acid
