What are the precautions for digging wild vegetables?

After Tomb-Sweeping Day, the soil in spring generously exudes a fragrant smell, and the vast fields are covered with a new green. In such fine weather, we can see many people digging wild vegetables by the roadside with shovels, washing the dug wild vegetables, steaming steamed buns, wrapping jiaozi or dipping them in sauce, all of which are delicious. However, picking wild vegetables also needs attention.

Don't eat wild vegetables whose shapes and sources are unknown, so as to avoid eating poisonous plants and contaminated wild vegetables by mistake. There are special branches and leaves, and yellow, orange and white wild vegetables are generally inedible. Cruciferae wild vegetables are safer. Don't touch those with white milk.

When picking wild vegetables, avoid contaminated areas, such as chemical plants, sewage, highways, landfills and other areas to avoid eating contaminated wild vegetables. Even the wild vegetables in the park may have been treated with pesticides and insecticides, and the irrigation can not meet the standard of drinking water, so it is not recommended to eat them. It's best to pick in the open suburbs, away from garbage dumps, sewage ditches and roads.

It is forbidden to dig wild vegetables on the roadside and in the suburbs. There will be automobile exhaust, smog and pollution rich in pollutants, which will lead to excessive heavy metals and lead, and the safety of wild vegetables is not guaranteed.

In spring, there are not only wild vegetables that come out of the ground, but also some wild vegetables that grow on trees, such as thorn buds, Chinese toon buds, elm money, etc., which are very popular among these masters. If you want to keep the original ecology of your mouth and stomach, the best way to eat such wild vegetables is steaming, cold salad or dipping in sauce. If it is made by heating, it is hard to say about the mouth and stomach, and the foundation of nutrition has flowed away.

For people with allergies, we must pay attention to whether there are itching, shortness of breath, coughing, sneezing and other phenomena when picking to prevent allergies.

Remember to wear gloves when digging and cleaning wild vegetables: Because most wild vegetables are rich in furan coumarin, this photosensitive substance will cause skin erythema and pigmentation after ultraviolet irradiation, which will increase the incidence of solar dermatitis.

You should also pay attention to wild vegetables after picking, and you can't eat them casually.

Wild vegetables should be eaten in a reasonable way as soon as possible after picking, and should not be stored overnight or left for too long, otherwise it may produce toxins and destroy a lot of nutrients.

In addition, there are some taboos between some wild vegetables and drugs. People who often take painkillers, sulfonamides or allergies should be careful when eating.

Wild vegetables must be soaked in water for more than 2 hours before eating, and it is best to blanch them with hot water. The surface of wild vegetables contains dust and insects, which may cause allergies. It is more hygienic to blanch with boiling water before eating, and it will not affect the taste and nutrients. If Toona sinensis contains nitrate and nitrite, blanching in boiling water for about 65438 0 minutes can remove more than 2/3 of nitrite and nitrate, keep Toona sinensis green and improve food safety.

Don't be greedy when eating wild vegetables. Wild vegetables can adsorb dust and suspended solids in the air, and spring is the season for eggs to revive. Therefore, it is suggested that wild vegetables should be thoroughly washed and scalded before eating, and wild vegetables should be eaten less and more.

In addition, I suggest you be careful when picking wild vegetables. Never pick wild vegetables you don't know. You'd better go with experienced people.
