Where are the main production areas of rapeseed oil? f

The main production areas of rapeseed oil are mainly in the Yangtze River basin and southwestern provinces, and the output ranks first in the world. Ordinary rapeseed oil is dark yellow, contains the characteristic smell of rapeseed, and has an astringent taste, and is a semi-dry oil. Crude canola oil is black-brown in color, and refined is golden yellow.

Rapeseed oil is commonly known as rapeseed oil, also known as rapeseed oil, coriander oil, brassica oil, sesame oil, canola oil, is a kind of edible oil squeezed from rapeseed. After nearly 10 years of efforts, China has transformed the traditional low-quality canola oil into the best nutritional quality of canola oil in bulk vegetable oils, and by 2010, China's rapeseed double low rate reached more than 90%.

Nutritional value of canola oil.

Canola oil is rich in vitamin E

Carotene, saturated and unsaturated fatty acids.

Phospholipids, sterols, stigmasterol, squalene, campesterol, cyclopineapple.

Enol, etc. The absorption rate of rapeseed oil by the human body is extremely high, which can reach 99%. Rapeseed oil is rich in unsaturated fatty acids and vitamin E, which can make the human body absorb the nutrients well, which is of great significance for softening blood vessels and delaying aging.

The raw material used in rapeseed oil is the fruit of the plant, so the finished rapeseed oil contains a certain amount of seed phospholipids, which play an important role in the development of blood vessels, nerves, and brains in the human body.

Canola oil contains almost no cholesterol.

Therefore, for people who control their cholesterol intake, they can eat canola oil with confidence.

Rapeseed oil has a relatively high content of erucic acid, and there is still controversy about whether it will cause myocardial fat deposition and cause heart damage, so coronary heart disease is a problem.

and high blood pressure.

patients, try to eat less canola oil.

Rapeseed is a kind of rapeseed that can be squeezed for oil, and the application value is very high.

1. Where is rapeseed produced?

Spring-sown rapeseed is produced in Inner Mongolia, Qinghai, Xinjiang, Gansu, etc., among which Hailar area of Inner Mongolia is the most concentrated. The production areas of rapeseed oil sown in autumn and winter are in Jiangsu, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Chongqing, Yunnan, Sichuan, Guizhou, etc., of which Hubei is the largest producing province and Sichuan is the second largest producing province.

2. How to extract oil from rapeseed?

1. Clean up the dried rapeseed.

If the soil, stems and leaves and other debris entrained in the rapeseed are not removed before entering the oil press, it will not only affect the quality of the oil and cake, but also adsorb a part of the oil and reduce the oil yield. If rapeseed is sandwiched with sand, metal, hemp rope and other sundries, it will cause wear and tear of machine parts, induce production accidents, and affect the process effect. Therefore, in order to ensure the smooth progress of production, it is necessary to remove impurities as much as possible, and it is also necessary to dry individual rapeseed fruits with high water content in order to facilitate shelling.

2. Heat treatment.

Heat treatment is one of the most important processes in the process of extracting oil, including the wetting and heating of the green billet, which is called steamed billet or fried billet in production, and the steamed billet is called cooked billet. The green billet that is pressed after heat treatment is called hot pressing, and those that are not heat treated are called cold pressing. Canola is mainly hot-pressed.

The effect of heat treatment has a direct impact on the smooth progress of the whole oil making process, the level of oil yield, and the quality of oil and cake.

3. Pressing. The circular press strip of the oil press is a zigzag curve and cone, when the rapeseed is pressed, it is pushed and extruded by the snail to make the volume of the inner wall space of the snail and the press cage constantly change, the inner wall of the press cage is zigzag because of the arrangement of the round press bar in the rear part of the press cage, the blank is pressed and relaxed alternately here, and the structure of the blank is constantly adjusted, and it is evenly turned, so that the oil that has not been squeezed out or the blank with less oil has more opportunities to be fully pressed.

In general, rapeseed is produced in many areas and is cultivated in most parts of China, among which Hubei and Sichuan are the largest producing provinces in China.

Rapeseed is planted in 32 provinces in China, and the main producing areas are Inner Mongolia, Xinjiang, Hanzhong Basin, Yunnan, Qinghai, Hubei, Hunan, Anhui, Sichuan and other places, and the total planting area accounts for about 60% of the country.

Domestic rapeseed oil raw materials are imported. Rapeseed oil is commonly known as rapeseed oil, also known as rapeseed oil, coriander oil, brassica oil, sesame oil, canola oil, is a kind of edible oil squeezed from rapeseed. It is one of the main edible oils in China, mainly produced in the Yangtze River basin and southwest and northwest places, and the output ranks first in the world, so that the traditional inferior high canola oil has become the best nutritional quality of low canola oil in bulk vegetable oil, and by 2010, the double low rate of rapeseed in China has reached more than 90%.

Production. The use of sandwich pot can also be used with two pots, the sandwich can be filled with grass ash or fine sand, when starting to fry, the fire can be slightly larger, about 0.5 hours later, the rapeseed in the pot has a burst sound, that is, the fire should be controlled. Ten minutes before the rapeseed out of the pot to suppress the flame, when the temperature of the rapeseed in the pot reaches 115 to 120 degrees, when the hand-twisted rapeseed is golden brown after crushing, it can be turned frequently when stir-frying.

To be precise, it can be divided into three types: raw canola oil, cooked canola oil, and mixed canola oil (refined canola oil). Raw pressing refers to lettuce, oil extraction, and oil extraction.

Linoleic acid and vitamin E levels are highest in the absence of high temperatures. Ripening is the process of frying rapeseed before extracting oil. High temperatures can lead to the loss of some nutrients.

Whether it is raw pressing, cooked pressing, or stir-fried in rapeseed oil, it must be preheated, which is commonly known as dry and grinding frying. A dish can only be fried if the oil itself is fried. The frying time of raw squeezing is longer than that of cooked pressing.

Therefore, even if the nutrition is relatively comprehensive, it is inevitable that there will be nutrient loss during the frying process. So I don't think there's much difference in the end. Of course, a type of rapeseed oil that has been refined before the oil mill leaves the factory is also used in the market.

It is usually unclear and pure, and is mixed with other oils, so it is also known as mixed canola oil. The advantage is that you don't need to preheat, you can cook directly. I like to use cooked canola oil because crude canola oil contains erucic acid, which affects the nutritional value.

As for the nutrition of raw meal pressing, it is actually useless, because nutrients will also be lost during the preheating process. The least valuable is the mixed canola oil.

Is canola oil better raw or cooked?

Hello, raw mustard oil is relative to cooked mustard oil. Canola does not need to be fried. Directly put into the hydraulic press to press the bucket press, often need to be pressed twice (remember that one press cannot be completely pressed, and the propaganda of one press is false propaganda).

When pressing, you need to fry the rapeseed first and then press the rapeseed. The color of the oil will be the same and more fragrant. Because raw mustard oil needs to be repressed, the oil is extracted much slower.

Shandong Huade hydraulic press manufacturers, for you to answer. I am happy to communicate with you and hope mine can be helpful to you.

Hello, it is my pleasure to serve you and give you the following answer: The largest place where rapeseed oil is produced in Russia is Moscow, which is the largest city in Russia and the largest economic center of Russia. Moscow produces more than 60 percent of Russia's rapeseed oil and is the largest producer of rapeseed oil in Russia.

To solve the problem of excessive rapeseed oil production in Moscow, the first measures to be taken are to strengthen the management of rapeseed oil, improve the quality of rapeseed oil, and increase the quality of rapeseed oil in order to reduce the production of rapeseed oil. Secondly, it is necessary to strengthen the scientific research of rapeseed oil, promote new rapeseed oil, and promote energy-saving and environmentally friendly rapeseed oil technology to reduce the consumption of rapeseed oil. Finally, it is necessary to strengthen the market development of rapeseed oil, expand the export market of rapeseed oil, and expand the new use of rapeseed oil to increase the demand for rapeseed oil.

Personal tips: To solve the problem of excessive rapeseed oil production in Moscow, it is necessary to take scientific management measures to improve the quality of rapeseed oil, improve the quality of rapeseed oil, promote new rapeseed oil, promote energy-saving and environmentally friendly rapeseed oil technology, expand the export market of rapeseed oil, and expand new uses of rapeseed oil to effectively control the production of rapeseed oil.
