vegetables with special flavor are relatively safe According to the statistics of China’s agricultural products monitoring center, the qualified rate of agricultural residues in vegetables from low to high is: beans (cowpea, concanavalis, etc.), eggplant (pepper, eggplant, etc.), Chinese Cabbage (cabbage, Chinese cabbage, etc.), green leaf vegetables (spinach, Youmai vegetable, etc.), taro potato root vegetables (potatoes, etc.), onion and garlic, melons (cucumber, wax gourd, etc.), the highest is edible fungi. In this way, cowpea, concanavalis and other agricultural residues pass rate is low, buy and eat attention. In addition, coriander, fennel and chrysanthemum have special fragrance, which is a kind of natural insect repellent, with low probability of infection of diseases and insect pests, and can be eaten with ease.

and

were relatively less in winter. If the pesticide residues were sorted according to seasons, the order was as follows: Summer > spring, autumn > winter. The leafy vegetables in winter, spring and autumn are relatively safe, and almost no pesticides are applied because of the few insects. There are more insects in summer, and most of them are planted in the open air.

and

what we eat is nothing more than vegetables and fruits grown in the open air or greenhouse vegetables. The former is more natural and tastes better, but it is difficult to control diseases and insect pests. In greenhouse vegetables, physical methods such as virus prevention net can be used to control pests, which has advantages in reducing pesticide residues.

,

and “wormhole” vegetables may not be safer. Many consumers believe that vegetables with wormholes are safer to eat without pesticides. But in fact, the presence or absence of wormholes does not determine whether pesticides have been used. According to the growth cycle of vegetables, in order to prevent diseases and insect pests, vegetable farmers often spray pesticides in the early stage. The vegetables that consumers see with insect eye are often vegetables that have been on the market for a long time, and pesticide residues may be higher. Therefore, don’t blindly think that vegetables with insect eyes are not sprayed with pesticides. When washing

and

, it is necessary to scrub under running water. It is found that the mechanical movement plays a key role in the removal of pesticides, but has little to do with the solubility of pesticides. Therefore, when we do not know the types of pesticide residues in vegetables, it is recommended to wash them with running water and rub them gently at the same time.

and

blanching for a short time is more effective, and high-temperature heating can decompose pesticides. Blanching can remove about 80% of pesticide residues, especially spinach, cabbage, rape, cabbage, cabbage and other leafy vegetables, while beans, celery and cauliflower can be boiled for a few minutes to reduce pesticide residues by 30%. Most of the pesticide residues are generally on the skin of vegetables and fruits. Cucumber, carrot, apple, pear and so on are best peeled and eaten. The above content of
