Vegetable oils are made from plants that contain unsaturated and semi-saturated fatty acids. During the manufacturing and refining process, three methods are used to extract vegetable oils from their seeds.
The first method: This method is done by traditional methods that depend on pressure or a simplified mechanical squeezing called the method of cooling pressure, after using heat in the manufacturing process, and if it is used in small quantities as a result of the pressure used and the temperature remains low and suitable for vitamins, and then the filtering process is done by sifters to remove The impurities are deposited, thus preserving the oil’s nutritional value and taste. ,
The second method is used, in which the spiral pressure is used, which is created by a pressure of a force of up to several hundreds of air pressure and a temperature rise to 160 – 250 degrees Celsius, as this temperature eliminates the vitamins in the oil as the oil becomes darker in color and has a strong odor, and they get rid of the color and odor. Manufacturers refine the oil and use synthetic deodorants.
The third method, and this method is done by dissolving, where the raw materials containing oil are collected and treated with steam. Oil and deodorization from it by treatment.
Benefits of vegetable oils
Vegetable oils such as sunflower oil help to regenerate cells because they contain vitamins that strengthen the eyes and liver and develop them, improve the health of the immune system and the digestive system, and protect body tissues. It also improves blood sugar levels, replaces carbohydrates and saturated fats with unsaturated fatty acids, controls insulin secretion, and reduces inflammation. As for heart disease, it reduces the risk of developing it, as it works by increasing the level of sugar in the blood and increasing blood pressure. And it benefits the skin and hair, as it includes cosmetics and shampoos.
