What are the main producing areas of peanuts in China?
The peanut, originally named groundnut, is an annual herbaceous plant of the Fabaceae family in the order Rosales. It prefers warm climates and sandy soil areas with moderate rainfall, and has a relatively long growing season. Peanuts are a common food in our daily lives, but do you know where the main producing areas of peanuts are? So let's take a look together at where the main producing areas of peanuts are!
Peanut producing areas in China
The peanut is one of China's three major oil crops, and its cultivation area is very extensive. It is grown throughout the country except in the three provinces of Tibet, Qinghai and Ningxia. The peanut producing areas for domestic consumption and export are mainly concentrated in the North China Plain and the coastal areas of the Bohai Sea, among which exports to Europe mainly come from Shandong, Liaoning, Hebei and other provinces. Because of suitable climate and soil conditions, the peanuts produced in these provinces are of high quality and good taste, and enjoy a good reputation internationally. The total peanut export volume of these provinces accounts for more than 85% of the national total.
How to eat peanuts
The healthiest way to eat them is boiled peanuts, which retain the original plant active substances in peanuts, such as phytosterols, saponins, resveratrol and so on, and have a significant effect on preventing malnutrition and preventing diabetes and cardiovascular disease. In particular, the β-sitosterol contained in peanuts has the effect of preventing colorectal cancer, prostate cancer, breast cancer and cardiovascular disease. In addition, resveratrol has strong biological activity, not only can it prevent cancer, but it can also inhibit platelet aggregation and prevent the occurrence of myocardial infarction and cerebral infarction.
However, while enjoying the delicious taste of peanuts, we must also pay attention to safety. Peanuts are the crop most easily infected by Aspergillus flavus. And aflatoxin is recognized worldwide as the strongest carcinogen discovered so far.
So, how should peanuts be eaten to be safe and beneficial? First, remove the peanuts that appear yellow-green in appearance, then soak and rinse them with running water, and then cook them in water before eating. Aflatoxin is very heat-resistant, and even heating to 200°C cannot destroy it. But aflatoxin is soluble in water, and after rinsing and boiling, most of it can be removed. From this point of view, eating cooked peanuts is relatively safer.
