Peanut producing area in China

Peanut is one of the three major oil crops in China, which is planted in a wide area, except Xizang, Qinghai and Ningxia. Domestic consumption and export peanut producing areas are mainly concentrated in the North China Plain and the coastal areas of the Bohai Sea, of which exports to Europe are mainly Shandong, Liaoning, Hebei and other provinces. Due to the suitable climate and soil conditions, the peanuts produced in these provinces have high quality and good taste, and enjoy a good reputation in the world, with the total export of peanuts accounting for more than 85% of the country's total.

Edible methods of peanuts

The healthiest way to eat is boiled peanuts, which retains the original plant active substances in peanuts, such as plant sterols, saponins, resveratrol, etc., which plays a significant role in preventing malnutrition, diabetes and cardiovascular diseases. In particular, β-glutenin in peanuts can prevent colorectal cancer, prostate cancer, breast cancer and cardiovascular diseases. In addition, resveratrol has strong biological activity, which can not only prevent cancer, but also inhibit platelet aggregation and prevent the occurrence of myocardial infarction and cerebral infarction.

However, while enjoying the delicacy of peanuts, we should also pay attention to safety. Peanuts are the crops most susceptible to Aspergillus flavus. Aflatoxin is recognized as the strongest carcinogen found so far in the world.

So, how to eat peanuts is safe and beneficial? First of all, the appearance of yellow-green peanuts should be removed, then soaked in flowing water, rinsed, and then cooked with water. Aflatoxin is so heat-resistant that it cannot be destroyed even if heated to 200 ℃. Aflatoxin is soluble in water, and most of it can be removed after rinsing and boiling. From this point of view, eating cooked peanuts is relatively safe.
