vegetable oil is not unfamiliar to everyone. People who often cook in the kitchen are very familiar with it. Vegetable oil is not a kind of oil, but a general term. There are many kinds of vegetable oil, such as rapeseed oil, which we often use. The name of vegetable oil is naturally extracted from plants, so many people want to know what the ingredients of vegetable oil are when they use plants.
vegetable oil from the beginning of people’s unfamiliar with it, to now most people will use it, but also has a period of process to let people know it. Compared with other oils, vegetable oil has many advantages for human body, and it is rich in nutrition, suitable for all ages. So it’s very popular with people. Today I would like to share with you the ingredients of vegetable oil.
in terms of nutritional value, soybean oil contains 7-10% palmitic acid, 2-5% stearic acid, 1-3% arachidic acid, 22-30% oleic acid, 50-60% linoleic acid and 5-9% linolenic acid. Soybean oil is rich in linoleic acid, which can significantly reduce serum cholesterol content and prevent cardiovascular disease. Soybean also contains a large amount of vitamin E, vitamin D and lecithin, which are very beneficial to human health. In addition, the digestibility of soybean oil is as high as 98%, so soybean oil is also an excellent edible oil with high nutritional value.
composition of oil:
the main composition of oil is the ester formed by higher fatty acids and glycerol,
is called triglyceride. The local flavor of hydrocarbon can be saturated or unsaturated hydrocarbon, which can be the same or different. If the hydrocarbon groups are the same, such oils are called monoglycerides. If the hydrocarbon groups are different, they are called mixed glycerides. Most natural oils and fats are mixed glycerides.
the saturation degree of fatty acids that form oil has an important influence on the melting point of oil. Glycerides formed by saturated palmitic acid or hard rich fatty acid have high melting point and are solid at room temperature. Animal oil, such as mutton oil, butter, etc; Glycerides formed from unsaturated oleic acid have low melting point and are liquid at room temperature. For example, the main component of vegetable oil is oleic acid glyceride
. First of all, vegetable oil is rich in unsaturated fatty acids, which are essential fatty acids for human body, because our body itself can not synthesize this component. According to the chemical structure of fatty acids and their different roles in the body, unsaturated “essential” fatty acids can be divided into two groups:
} linoleic acid: it can accelerate the metabolism of skin cells, enhance immunity, help the regeneration of blood coagulation, and reduce cholesterol.
▲ α- Linoleic acid: plays a very important role in the visual system and nervous system, and can reduce the level of triglycerides in the blood, thus reducing the formation of atherosclerosis and thrombosis. So unsaturated fatty acids have the effect of preventing cardiovascular disease. Secondly, vegetable oil is the best source of vitamin E. Vitamin E is a fat soluble vitamin with antioxidant properties, which can devour the free radicals that lead to aging. Plant fat is rich in vitamin E. Edible vegetable oil: human diet needs to ensure the content of oil. If the human body is short of fat for a long time, it will suffer from malnutrition, poor physical strength, weight loss and even loss of working ability. Edible vegetable oil is an important non-staple food for human beings. It is mainly used in cooking, pastry, canned food and so on. It can also be processed into vegetable oil, margarine, baking oil and so on for people to eat.
2. Vegetable oil for industrial use: it is widely used as the main raw material for soap, paint, ink, rubber, leather, textile, candle, lubricating oil, synthetic resin, cosmetics, medicine and other industrial products.
3. Vegetable oil is one of the important commodities in the international market. With China’s reform and opening up and the development of national economy, the variety and quantity of import and export vegetable oil are increasing year by year. Vegetable oil exports include soybean oil, peanut oil, rapeseed oil, palm oil, castor oil, etc., mainly exported to Japan, North Korea, Mongolia, the Netherlands, Russia and other countries. Vegetable oil imports include soybean oil, rapeseed oil, coconut oil, palm oil, flax oil, castor oil, etc., mainly from the United States, Brazil, the Netherlands, the Philippines, India, Singapore, Malaysia and other countries.
above is to introduce the composition of vegetable oil, I believe you have a certain understanding of the composition of vegetable oil. Vegetable oil is not only delicious, but also nutritious, so you can use vegetable oil to make some delicious food for your family.
