What are some practices that can help eliminate pesticide residues on vegetables and fruits?

At present, there are two methods: one is to use the commonly used method to clean with water or chemical reagents, and pesticides are highly toxic organic substances, and their macromolecular structure cannot be decomposed by water and chemical inorganics; Soaking with water or soaking and cleaning with detergent, can remove a small amount of residual pesticides on the surface of vegetables and fruits, but can not fundamentally solve the problem, with chemical detergents for pesticide residues is useless, while causing secondary pollution to the food itself and the environment at the same time, there is a way to use a pure biological reagent, Bia vegetable degradation enzyme, is the use of biotechnology to degrade the molecular structure of organophosphorus into water and small molecules, but this technology has just been studied by scientists of the Chinese Academy of Agricultural Sciences for the first time, Its principle of action is to degrade highly toxic macromolecules into non-toxic small molecules dissolved in water, but there is no secondary pollution to the environment, and it is non-toxic and non-toxic to the human body.

Buy that kind of fruit and vegetable washing machine, often advertised on TV, there is a washing machine for washing clothes, and there must be a vegetable washing machine for washing vegetables, the kind that is useful for concealment, buy one that can be used for a long time, and you can filter out those unclean things outside.

Soaking it in salt water is fine, and it removes small bugs quickly. Simple and practical.

Soak it in water to dissolve the pesticide the most.

Blanching with boiling water can remove pesticides very well.

It's summer homework.

We all know that we buy vegetables and fruits in the vegetable field or supermarket have pesticide residues, chemical pesticides can not be removed by ordinary washing, so that after being eaten by the human body, it is easy to accumulate in the body, not only will have direct harm to humans and animals, but also will destroy the function of the liver, lead to cancer, pregnant women accidentally eat vegetables containing pesticide residues will likely produce deformed freaks, serious may cause acute kidney failure and death. Therefore, learning how to effectively remove pesticide residues from fruits and vegetables is a must-have common sense for every family.

It is important to know that due to the different forms of each vegetable and fruit, the parts of pesticide residues are also different, and the methods of removing pesticides are also different.

1. Alkaline water soaking

Organophosphate insecticides can decompose quickly in an alkaline environment, so this method is suitable for all kinds of vegetables and fruits. The method is to add 5 to 10 grams of alkaline noodles to 500 ml of water, rinse the dirt on the surface of vegetables and fruits, soak them in alkaline water for 5 to 15 minutes, and then rinse them with water 3 to 5 times.

2. Peel

Peeling is a good way to remove pesticide residues. It can be used for apples, pears, kiwis, cucumbers, carrots, winter melons, pumpkins, zucchini, eggplants, turnips, etc.

3. Soaking

The pesticide varieties polluted by vegetables are mainly organophosphorus insecticides, and the organophosphorus insecticides are insoluble in water, and this method can only remove part of the polluted pesticides. However, washing is the basic method of removing other dirt and removing residual pesticides on vegetables and fruits, and is mainly used for leafy vegetables, such as spinach, enoki, leek flowers, lettuce, cabbage, etc. Generally, the surface dirt is rinsed off with water first, and then soaked in water for no less than 10 minutes.

Fruit and vegetable cleaning agent can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaning agent can be added when soaking. After soaking, rinse with running water two or three times.

4. The storage family is rotten

Pesticides can slowly decompose into harmless substances over time during storage. Therefore, fruits and vegetables that are easy to preserve can be stored for a certain period of time with less pesticide residues. It is suitable for non-perishable species such as apples, kiwifruit, and winter melons.

Generally, it is stored for more than 15 days.

5. Heating

Carbamate insecticides decompose faster as the temperature increases. Therefore, some vegetables and fruits that are difficult to treat by other methods can be removed by heating. It is often used in celery, spinach, bok choy, cabbage, green pepper, cauliflower, beans, etc.

Wash the surface dirt with clean water, put it in boiling water for 2 to 5 minutes and remove it, then wash it with clean water.

One or two times. These methods are effective methods to remove ordinary pesticides, although these methods are slightly more cumbersome than our daily cleaning, but the body is our own, and these more steps are also responsible for our body, so we must not be lazy.

There are several ways to remove pesticide residues from fruits and vegetables. Soak the vegetables and fruits in salted water, peel the vegetables and fruits, blanch the vegetables, and soak the vegetables and fruits in floured water.

There are residual pesticides in vegetables and fruits, and if you want to eat healthy and safe, you must wash vegetables and fruits well. Some people wash vegetables and fruits directly with water, so that they cannot wash away the residual pesticides on vegetables and fruits, and the best way is to add a little salt to the water and then soak them. After a few minutes, the vegetables and fruits are taken out and cleaned, and the residual pesticides can be effectively removed.

Pesticides left on vegetables and fruits are harmful to the body, and if you want to remove them completely, you have to peel them. Vegetables and fruits can be peeled as much as possible, such as eggplant, cucumber, horn melon, loofah, apple, white pear, etc., we have to take the peeler to peel. Peeling and removing pesticides is the most effective and makes us safer to eat.

For example, grapes, oranges, oranges, grapes, etc. can be peeled and eaten directly, and they must be peeled before eating, so that it is safer.

There are many tips in life, in order to better remove the residual pesticides on vegetables, we can use the blanching method. Put water in the pot, boil the water, blanch the washed vegetables in the pot, take them out for 1-2 minutes, quickly cool them, control the moisture and set aside. This method is suitable for green leafy vegetables such as spinach, rape, bok choy, lettuce, etc., as well as vegetables such as broccoli, cauliflower, snow peas, etc.

This method can be used when pesticides are difficult to clean from pesticides left on vegetables and fruits. Add some flour to the water, soak the vegetables and fruits in it, and after a few minutes, you will find that there will be a lot of dirt in the water, and the vegetables and fruits will be washed very clean. You can also put some starch in the water, and then put the vegetables and fruits in to wash, and it will also be clean.

It is not recommended to eat the vegetables and fruits you buy immediately, and it is best to leave them for a day before eating, which can reduce the residue of pesticides.

The use of fruit and vegetable cleaning agents can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaning agents can be added when soaking. After soaking, rinse it with running water two or three times. Chinese cabbage, cabbage, cabbage and other vegetables, before eating, these vegetables can be broken into leaf by hand, and then soaked in salt water for a period of time, when soaking vegetables, it is best to let each side of the vegetables fully contact the salt water.

Many fruits will have pesticide residues, eating in the human body will be harmful to the body, if you want to eliminate excessive pesticide residues, you should clean the fruit or peel it to eat.

Vegetables and fruits can be soaked in hot water or sterilized in a microwave oven, and light waves can be used to kill insects.
