Which rapeseed has the highest oil yield? What is the oil yield of rapeseed

Which rapeseed has a high oil yield The rapeseed oil yield is in accordance with the high national standard of seed quality: grade 1 oil content grade oil content grade oil content grade oil content grade 33%. For example, Wan Essential Oil, Jiayouzan, and Western Sichuan people are all low-quality rapeseed varieties with short plants, good resistance and high oil yield.

The climatic conditions in which rapeseed is grown affect the plumpness and oil content of rapeseed. Generally speaking, the oil yield of rapeseed in the oil press is about 32%-36%.

In general, canola is divided into two categories. Cauliflower oil production high, in the best case there is 36 38. Black rapeseed is about 35. This is related to the local climate and precipitation, the degree of dryness and wetness of rapeseed and the processing equipment.

Under normal circumstances, the oil yield of rapeseed is . Depending on the type of rape, the oil content varies slightly. Rapeseed is one of the main oil crops and nectar crops in China, and its grains are one of the main varieties of raw materials for oil and fat.

Oily rapeseed.

Rapeseed, also known as brassica, is the seed of the cruciferous crop rapeseed, which has long horns, many pods, and full grains.

There are two types of rape: winter rape and spring rape. Its planting area accounts for more than 40% of the total area of China's oil crops, and the output of Shenma accounts for more than 30% of China's total oil crop output, ranking first in the world.

Rapeseed is one of the main oil crops in China, and the cultivation methods are divided into two types: seedling transplanting and no-tillage direct seeding, and most of the planting areas mainly adopt seedling transplanting methods.

Rapeseed (Rapeflower) is the only high-oil oil crop that can be grown all over the world, and it is divided into two types: winter rape and spring rapeseed. Its planting area accounts for more than 40% of the total area of oil crops in China, and the oil content is 35%-50%. Oil yield:

The quality of rapeseed varies by 30%-45% depending on the region

Rapeseed in different regions due to different geographical environment, the oil content of rapeseed produced by it is also different, at present, rapeseed in China mainly includes cabbage-type rapeseed, mustard rapeseed and cabbage-type rapeseed. Among them, the oil content of cabbage rapeseed is high, and with the progress of science and technology, China has been conducting research on rapeseed varieties, such as double high rapeseed (high yield and high oil), and the oil content of conventional rapeseed variety G142 with high oil content is as high as 45%.

For rapeseed oil yield which is the highest, in addition to the oil content of its own relationship, but also with the processing equipment, such as the oil press, the lower the oil residue rate of the oil press, the more oil squeezed. Rapeseed is generally hot pressed, and the time and temperature of steaming and frying will also affect the oil yield of rapeseed.

Zhongshuang No. 11, Zhongyouza 13.

1. Zhongshuang No. 11 is a rapeseed variety bred by the Institute of Oil Crops, Chinese Academy of Agricultural Sciences, with the variety (Zhongshuang 9 2F10) 26102. On December 2, 2008, the second meeting of the second National Crop Variety Examination and Approval Committee was approved, and the approval number was the National Oil 2008030.

2. Medium oil miscellaneous 13

Zhongyouza 13 is a semi-winter cabbage type rape. The plant is taller, the growth potential is more vigorous, the branch part is low, and the lodging resistance is average.

It integrates high yield, high quality and high oil, and it is still Zhongshuang No. 11 of China Petroleum Institute.

Development status The Yangtze River basin is the main rapeseed producing area in China and the world's largest concentrated rapeseed production area. The whole basin covers an area of more than 1.8 million square kilometers, involving 11 provinces (municipalities) including Shanghai, Zhejiang, Jiangsu, Anhui, Hubei, Jiangxi, Hunan, Sichuan, Guizhou, Yunnan and Chongqing, as well as Xinyang area of Henan, and the sown area and output of rapeseed account for more than 85% of the country. The Yangtze River basin is rich in agricultural resources in winter, and it is an advantageous production area of "double low" rapeseed in China, with unique development advantages.

1.Basic Facts 1The production area is relatively concentrated.

Rape is one of the five crops (rice, corn, wheat, soybean and rape) with a planting area of more than 100 million mu in China. China's rapeseed production is widely distributed, at present, in addition to Beijing, Tianjin, Liaoning, Hainan, the other 27 provinces (autonomous regions, municipalities) are planted, of which the top five output is Hubei, Anhui, Jiangsu, Sichuan and Hunan. According to the different climatic and ecological conditions, China's rapeseed production can be divided into four regions, namely the winter rape area in the Yangtze River Basin, the northwest rape area, the spring rape area in Northeast China and the winter rape area in South China.

Among them, the winter rape area in the Yangtze River basin is the most concentrated rapeseed production area, with an area of 92.39 million mu and an output of 10.18 million tons in 2001, accounting for 87% and 89% of the country, accounting for more than a quarter of the world, higher than Europe and Canada.

2.Production is developing rapidly. Since the reform and opening up, especially after 1990, China's rapeseed production has developed rapidly, and the area has surpassed peanuts to become the largest oil crop.

In 2001, compared with 1990, the area expanded by 23.87 million mu, with an average annual increase of 2.17 million mu; Yield increased by kilograms, an increase of 26%; Production increased by 4.37 million tons, an increase of 63%, with an average annual increase of nearly 400,000 tons.

3.Remarkable results have been achieved in quality improvement. "Double low" rape refers to low-erucic acid and low-sulfuroside rape.

According to the standards issued by the Ministry of Agriculture, the erucic acid content of commercial rapeseed is less than 5% (oil) and the glucoside content is 45 mol g (cake), commonly known as "double low" rapeseed. The contents of oleic acid and linoleic acid in canola oil were greatly increased, and the nutritional quality was significantly improved. Low-sulfuroside cake meal reduced toxicity and increased the utilization value of rapeseed cake meal.

For high crop yield, use Fengxin Agricultural Crop High Yield Program.

Under normal conditions, the oil yield of rapeseed is not very high, about 30% to 40% of Zhensen, that is to say, every 100 catties of rapeseed can produce about 30-40 catties of oil. There are many varieties of rapeseed, and the difference in varieties will also affect its oil yield. In addition, there are some areas where the climate is very good, and the oil yield will be higher.

1. Remove impurities: There is some sediment in the general rapeseed, and it is best to remove the impurities of these sediments before oil extraction, otherwise it will absorb oil in the process of oil extraction, which will also affect the oil yield to a certain extent.

2. Squeeze hot materials: Some people may not know that oil molecules are the most active when the temperature is high, so it should be carried out while it is hot, so that the amount of oil will be increased.

3. Add bran: When squeezing oil, you can add some bran to it, and sieve the ash contained in it when you use it. After blending, it can slow down the speed of rapeseed sliding, so it can extract more oil.
