Rapeseed oil is what we commonly call vegetable oil, also called rapeseed oil and coriander oil. It's edible oil squeezed from rapeseed. Rapeseed oil is golden or brown in color and has a certain pungent smell, which is called "green taste" by the people. This smell is due to the fact that it contains a certain amount of glucosinolates, which are not contained in excellent varieties of rapeseed.
Alias of raw materials: rapeseed oil, rapeseed oil, rapeseed oil, rapeseed oil, sesame oil and recently mustard oil, which are mainly produced in the southwest of China.

Rapeseed oil, commonly known as vegetable oil, is also called coriander oil, which is a transparent or translucent liquid obtained by squeezing the seeds of rapeseed. Rapeseed oil is golden or brown in color and has a certain pungent smell, which is called "green taste" by the people. This gas is caused by containing a certain amount of glucosinolates, but excellent varieties of rapeseed do not contain this substance, such as high oleic rapeseed oil and double low rapeseed oil.
It is one of the main edible oils in China, mainly produced in the Yangtze River valley, southwest and northwest, and its output ranks first in the world. The absorption rate of rapeseed oil by human body is very high, reaching 99%. Rapeseed oil has certain effects of softening blood vessels and delaying aging.
Because the raw material of oil pressing is plant seeds, it usually contains some seed phospholipids, which is very important for the development of blood vessels, nerves and brain.
Rapeseed oil contains almost no cholesterol, so people who control cholesterol intake can safely eat it.
Barreled rapeseed oil
Rapeseed oil is an oil with a particularly high erucic acid content. Whether it will cause myocardial fat deposition and damage to the heart is still controversial, so patients with coronary heart disease and hypertension should pay attention to eating less.
Chinese medicine theory holds that vegetable oil is sweet, pungent and warm.
It can moisten dryness, kill insects, disperse fire pills and reduce swelling and toxicity.
Yao Kecheng's Edible Materia Medica also said that vegetable oil "is applied to the head to make the hair grow black. Promote blood circulation to remove blood stasis, break cold, reduce swelling and dissipate stagnation. Dystocia, postpartum heart disease, redness and swelling, golden sore and bloody hemorrhoids are difficult to cure. " Clinically used for ascaris lumbricoides and food-borne intestinal obstruction, the effect is good.
It was first seen in Tiangong Kaiwu: "Anyone who eats oil ... is followed by rape."
Compendium of Materia Medica says that rapeseed is "fried with oil, yellow and bright, not as good as sesame oil." Being close to the people is profitable because of oil and extensive cultivation. "
Rapeseed oil, referred to as "rapeseed oil" for short, is mainly taken from oilseeds of rape and cabbage in Gan Lan (oil content is 22%-49%, with an average of 40%). It contains protein 2 1%-27%, and phospholipid is about 1%. These rapeseed varieties are produced in China, India, Japan, Pakistan, Sweden, Poland, Germany, Chile, France and Canada. In Europe, the source of vegetable oil is winter-sown Brassica napus. In Pakistan and Canada, the main sources of vegetable oil are
Sow rape in summer.
Rape production in China has made great progress, and the yield per mu has been continuously improved. Rapeseed oil production accounts for more than 1/3 of vegetable oil production. In addition to the Yangtze River and Pearl River basins, other regions are also vigorously developing rape planting, because it can be planted in winter fallow areas without competing with field crops.
Rapeseed oil is yellow, slightly green, smelly and spicy. Rapeseed oil after alkali refining, decoloration and deodorization is clear and transparent, with light yellow color and no peculiar smell. The flavor recovered during storage, but it was different from the original flavor (crude oil).
A few years ago, rapeseed was pressed by rapeseed, and most of the rapeseed planted was Brassica napus. After germplasm cultivation, the erucic acid content of many varieties is less than 3%, and there are few "green flavors" in the past. The fatty acid composition of rapeseed from different producing areas varies greatly, and some rapeseed contains more than 50% oleic acid.
Nutritional components: The main components are erucic acid, oleic acid, linoleic acid, linolenic acid, tocopherol and brassinolide.
Sunflower seed, also called sunflower seed, is the fruit of sunflower. Its nuts contain 30%-45% fat, up to 60%. Sunflower seed oil is golden in color, clear and transparent, and fragrant in smell. It is an important edible oil. It contains a lot of unsaturated fatty acids such as linoleic acid, which can promote the regeneration and growth of human cells, protect skin health and reduce the accumulation of cholesterol in blood. It is a kind of advanced nutritional oil. Golden color, clear and transparent, fragrant smell. The consumption of sunflower oil in the world ranks fourth among all vegetable oils, second only to palm oil, soybean oil and rapeseed oil. The global sunflower seed oil output is stable at100000 tons-120000 tons. Sunflower seed oil is one of the important edible oil varieties in European countries. Many countries and regions in the world, such as Taiwan Province Province, Hongkong, Japan and South Korea, consume as much as 70% of sunflower oil.
The oil extracted from sunflower seeds is called sunflower seed oil, which is golden in color, clear and bright, and has some pleasant fragrance. It is the main edible oil for Europeans and Russians.
Sunflower seed oil is pure, clear and transparent, fragrant and delicious. Because it is rich in linoleic acid and rich in nutrients to maintain human health, it is known as "health care product", "advanced nutritional oil" or "health care oil" abroad.
Common brands are Li Duo, Lu Hua, Arowana and Fulinmen.

Sunflower seed oil contains sterols, vitamins, linoleic acid and many other substances beneficial to human body, among which the content of natural vitamin E is the highest among all major vegetable oils. The content of linoleic acid can reach about 70%. Sunflower seed oil can reduce serum cholesterol level, triglyceride level and blood pressure. Moreover, sunflower seed oil is light and transparent, which can retain the flavor of natural food when cooking, and its smoke point is also very high, which can avoid the harm of oil fume to human body.
The refined sunflower seed oil is clear and beautiful pale yellow or bluish yellow, with fragrant smell and pure taste. The composition of fatty acids in sunflower seed oil is influenced by climatic conditions. Sunflower seed oil produced in cold areas contains about 65438 05% oleic acid and 70% linoleic acid. Sunflower seed oil produced in warm areas contains about 65% oleic acid and 20% linoleic acid. The digestibility of sunflower seed oil is 96.5%. Rich in linoleic acid, it can significantly reduce cholesterol, prevent arteriosclerosis and prevent coronary heart disease. In addition, the content of tocopherol A with the strongest physiological activity in sunflower seed oil is higher than that in general vegetable oil. Moreover, the ratio of linoleic acid content to vitamin E content is relatively balanced, which is convenient for human body to absorb and utilize. Therefore, sunflower seed oil is an excellent edible oil with high nutritional value and beneficial to human health.
