Sunflower oil is a plant product that is obtained by pressing or extracting from oilseed sunflower varieties. It is the most popular type of oil used in cooking and cosmetology.
Sunflower is native to North America, and, according to historical data, the inhabitants of this continent used its oil for the preparation of medicines and dyes five thousand years ago. This plant was considered sacred, but not artificially cultivated.
It appeared in Europe thanks to Spanish sailors in the early 16th century. Great credit for improving the technologies for producing oil belongs to the British, who received the first patents for its production. Today sunflower oil is used in the food industry, medicine, cosmetology, agriculture, and also for technical purposes.
From this article you will learn about the main varieties, cleaning methods, where sunflower oil is used, its composition, how is sunflower oil useful and whether it has any contraindications for use.
In the times forgotten by the ancestors, the sunflower flower was considered an ornamental plant associated with the sun, it was worshiped, considered a sacred flower symbolizing wealth, health and fertility.
Sunflowers were planted in parks, estates, fields, they decorated vegetable gardens, but were not used in cooking or medicine. And only in 1829 the Russian peasants Daniil Bokarev, having planted several sunflowers in his garden, tried to be the first to beat the oil from the sunflower using a hand press.
After the successful extraction of sunflower oil, the first creamery was created in the village. At the end of the 19th century, sunflower seed oil was widely used not only in Russia, but in Europe and other Western countries.
Today, the production of sunflower oil accounts for about 70% of all vegetable oils and is widely used in all countries of the world. There are about 50 types of sunflowers, but oilseed sunflower, which is grown all over the world, is used for the production of vegetable oil.
In our time, sunflower oil is considered an important plant product that is widely used in cooking. In addition, given its unique and healing composition, this product is used to treat and prevent a number of diseases.
During the production of vegetable oil, sunflower seeds go through several stages of processing to obtain the desired type of oil, which has a pleasant aroma and specific taste.
Types of sunflower oil
Sunflower oil is obtained in two ways: by pressing and extraction. The first option is more environmentally friendly, moreover, in the final product it is possible to preserve most of the nutrients: vitamins, antioxidants. First of all, this concerns cold-pressed oil.
Hot-pressed oil is obtained by heating the mint in a brazier, which gives the product a characteristic taste reminiscent of roasted seeds. The extraction method involves the use of organic solvents. The process is carried out in special extractors, which contain a mixture of oil and solvent, as well as a solid product – meal.
The oil is obtained by distillation in distillers, followed by filtration. The method is economical, however, the nutritional value of the extracted product is significantly lower than that of the oil obtained using mechanical methods. Crude (first pressed) is cold or hot pressed oil that has a pleasant taste and can be easily purified (filtration or centrifugation).
When cold pressed, most of the vitamins and phytosterols are retained in the oil, but this technology is not used in its pure form, so the actual concentration of nutrients can vary greatly.
Hot pressing involves heating the mint up to 100 degrees, as a result of which most of the vitamins and phytosterols are destroyed. Depending on the method of purification, the following types of oil are distinguished:
Obtained by mechanical extraction followed by simple filtration of the oil. It has a pleasant smell and rich amber color. It is the leader in the concentration of nutrients and vitamins. The shelf life of the oil varies from 3 to 4 months.
Produced from unrefined by carrying out a full cleaning cycle. Such products contain a minimum amount of vitamins (a small amount of vitamins E, A, K is retained in it, and vitamins B and C, phytosterols are completely destroyed). The shelf life of the oil is about 1 year.
It is a product that is obtained by treating unrefined oil with water, which removes proteins and components containing phosphorus from it. In appearance, such oil is much more transparent and paler than unrefined, and more vitamins and other useful substances are stored in it than in refined. Can be stored for up to 6 months.
They are made from both unrefined and refined oils by removing waxes by freezing. This method prevents product cloudiness and sludge formation. This oil is used in the preparation of dietary meals, in the diet of children.
The oil undergoes additional filtration, which removes carotenoids, waxes and makes it the best choice for frying. It is the lightest of all oils in existence.
All components that are responsible for the taste and smell of the product are removed from such oil. It is widely used for frying.
Where is sunflower oil used
Sunflower oil is one of the most common vegetable oils, which is widely used in cooking (for frying, dressing salads), in the food industry (for making fats, in the production of canned food), as well as for technical purposes (for lubricating bearings, in soap making, paint and varnish industry).
The composition and benefits of sunflower oil
The composition of sunflower oil is quite variable and depends on the variety of sunflower and the place of its cultivation, the method of obtaining the product and methods of its purification. The product contains a large amount of fats that are not synthesized in the body and must come from outside, phytosterols, vitamins.
The oil contains the following fatty acids, which take part in the work of the nervous system, in the creation of the membranes of nerve tissues and cell membranes:
The beneficial properties of sunflower oil depend primarily on the method of its isolation and subsequent processing. The following vitamins are present in unrefined oil:
- Vitamin A (retinol). It is an important participant in the body’s metabolism. Its sufficient intake into the body allows maintaining the skin and the immune system in a normal state. Has a beneficial effect on the work of many internal organs.
- Vitamin D (calciferol). It is responsible for the normal growth and development of the skeletal system, helps prevent the development of rickets and osteoporosis. If the intake is insufficient, the thyroid gland is disrupted, and immunity is reduced. Numerous studies have proven the important role of vitamin D in preventing the formation of malignant cells.
- Vitamin E (tocopherol). It has a protective function, preventing oxidation of cellular structures. It participates in many vital processes in the body: it regulates sexual function, ensures the normal functioning of muscle tissues, stimulates the activity of cells, prevents increased blood clotting, slows down the aging process, etc.
- B vitamins (B1, B2, B3, B5, B6). They ensure the normal functioning of the nervous and cardiovascular systems, improve the functioning of the gastrointestinal tract, the condition of the skin, allow better tolerance of physical activity, stressful situations.
The benefits of sunflower oil for the human body are expressed in the following:
- improving the work of the cardiovascular system (lowering cholesterol levels, strengthening the vascular walls, protecting against atherosclerosis, severe vascular and heart pathologies);
- beneficial effects on the brain (improving cognitive functions);
- normalization of the gastrointestinal tract;
- positive effects on the endocrine and genitourinary systems;
- prevention of premature aging (due to the high content of tocopherol, which is three times higher than in olive oil).
Sunflower oil contraindications
Sunflower oil has practically no contraindications for use, but it must be consumed in moderation. Abuse adversely affects the health of overweight people, leading to an increase in blood glucose.
The use of sunflower oil is not recommended for people suffering from cholelithiasis, prone to allergies. The harm of sunflower oil to human health can be caused by the use of low-quality products.
Sunflower oil selection criteria
When buying sunflower oil, give preference to the one that is stored in a dark place – under the influence of light, the product loses its useful properties, and its shelf life is reduced. The closer the expiration date of the product, the higher the value of its peroxide value, which affects the oxidizability of the oil.
Products with a high peroxide value quickly lose their original properties and become rancid. Cloudy oil is a sign that the product is spoiled. In this case, the presence of sediment in unrefined oil is allowed, since most often its components are phospholipids useful for the body.
Sunflower oil in cosmetology
