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 source of vegetable oil is cabbage grown 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.
Extended data
A recent study by Pennsylvania State University found that eating rapeseed oil can effectively reduce abdominal fat. The researchers reported their experimental results at the annual scientific meeting of the Obesity Association on10.02/65438.
The researchers recruited 10 1 participants and randomly divided them into four groups. Each group ate common rapeseed oil, high oleic rapeseed oil, high oleic rapeseed oil rich in DHA (an omega-3 fatty acid), corn/safflower oil and flax/safflower oil respectively. There is a dietary test cycle every four weeks.
It was found that after one month, participants who insisted on eating rapeseed oil diet lost 0.25 pounds (about 0. 1 1 kg) and their abdominal fat decreased significantly. The researchers said that this is because rapeseed oil is rich in monounsaturated fatty acids, which is good for health, especially for obese people.
Researchers suggest that rapeseed oil should be integrated into the daily diet, and rapeseed oil can be used more when cooking, baking, making salads and making milkshakes. The researchers said that they will further explore the long-term health effects of eating more monounsaturated fatty acids (such as rapeseed oil) in the diet.
