1. Why do many vegetables have pesticide residues now?

With the continuous improvement of people's living standards, now the market is showing, everyone's vegetable types are becoming more and more, this is to meet everyone's growing material and cultural needs, more types of vegetables to meet, many people want to eat what vegetables to eat what vegetable needs, so the supermarket has all kinds of vegetables, winter to eat summer vegetables, summer to eat winter vegetables are very common, in order to be able to make vegetables in advance or out of season sales, so as to make more money, A lot of vegetable farmers have planted some out-of-season vegetables, but these out-of-season vegetables need to spend more energy, manpower and material resources in the process of planting, including some out-of-season vegetables, in order not to be disturbed by pests and diseases, will often use pesticides, which leads to a lot of vegetables still have a lot of pesticides when they are on the market, and these residual pesticides, if they often appear on everyone's table, will inevitably affect the health of consumers.

Now it is very normal for vegetables on the market to have pesticide residues, everyone is not surprised, on how to remove pesticide residues on vegetables, many people also have their own methods, first of all, you can buy back vegetables in the outdoor for about a day, the pesticides in the vegetables will be decomposed and oxidized, although these pesticides can not be completely removed, but also can remove a large part, and then the vegetables need to be soaked with water and edible alkali, Because pesticides can react with edible alkali, in this way, the pesticides in the vegetables have been removed, a large part, if you buy vegetables with skin such as potatoes and carrots, you can directly remove the skin, and you can also completely remove the pesticide residues, and the last method is that you must clean it in the process of cooking vegetables, and then it is best to boil it with water, which is also a very good way to remove pesticide residues.

It is relatively common for vegetables to have pesticide residues on rocks, and there are many ways to reduce them, one is to peel them as much as possible, the other is to soak and clean them before eating, and the other is to place them at room temperature, and after two or three days, the pesticide residues will also dissipate. Pesticide residues on vegetables are more common, cauliflower, beans, mustard greens, etc., after rinsing the jujube land, it can be scalded with 90 hot water before frying in the next pot, which can reduce the residual pesticide by 40, and then after cooking, you can remove more than 90 residual pesticides on vegetables.

Improper vegetable washing can cause pesticides to produce tumors, in order to reduce pesticide residues, it is best to scrub fruits and vegetables under the faucet, some fruits and vegetables with a "strong" appearance, you can also scrub them with a brush, feel clean, and then rinse them with water for 15 to 20 seconds to eat with confidence. Poisoning caused by improper processing or cooking, or by ingestion of poisonous plants and animals, including puffer fish, rotten vegetables, sprouted potatoes, sprouted seeds, and spoiled mushrooms, which fail to remove toxins from food.

<> as the temperature increases, the synthesis rate of carbamate insecticides accelerates. So for some other vegetables and fruits that are difficult to handle, local pesticides can be removed by heating. It is commonly used in celery, spinach, cabbage, cabbage, green pepper, cauliflower, beans, etc.

The method is to first rinse the surface dirt with water, put it in boiling water for 2-5 minutes, and then rinse with water 1-2 times. Organophosphorus pesticides are mainly used to pollute vegetables. Organophosphate insecticides are difficult to dissolve in water, so this method can only remove locally contaminated pesticides.

But washing is an essential way to remove other dirt and pesticide residues from vegetables and fruits. It is mainly used for leafy vegetables, such as spinach, goldenrod, leek flowers, lettuce, cabbage, etc.

In general, the surface dirt is rinsed with water first, and then soaked in water for no less than 10 minutes. Fruit and vegetable cleaners can promote the dissolution of pesticides, so a small amount of detergent can be added when soaking. After soaking, rinse with water 2-3 times.

Choose the regular market to buy vegetables. At present, many places have established an access mechanism for agricultural products, established a testing system in large wholesale markets, and carried out on-site testing of vegetables entering the wholesale market to ensure that vegetable pesticide residues are within the normal standard range and effectively reduce the harm of vegetable pesticide residues to human health. Although many places have established an access mechanism for agricultural products, but at present these systems are not perfect, the market testing of vegetables is only sampling testing, which does not mean that all vegetables are qualified vegetables, and some illegal profiteers are difficult to avoid fishing in troubled waters.

Therefore, when we buy vegetables, we should check whether there are "worm eyes" on the surface of the vegetables. In general, there are relatively few pesticide residues in vegetables with "insect eyes".

Don't worry about eating the vegetables you bought. It's better to leave it for a while. You can buy it in the morning and eat it in the evening.

According to relevant experts, leaving vegetables for a period of time can greatly reduce pesticide residues in vegetables, because the air will oxidize some pesticide residues. Soak in water. If there is rice washing water, it is recommended to soak it in the rice washing water.

When cooking rice, it is advisable to leave the rice washing water to wash the vegetables. If there is no rice washing water, soak the vegetables in clean water for about 20 minutes, and then rinse the vegetables with tap water to remove pesticide residues and oil stains on the surface of the vegetables. This can reduce pesticide residues by a small fraction.

Scald with hot water. Place the washed dishes in water at degrees Celsius to burn, usually for 2-3 minutes. If it is too long, the nutrients in the vegetables will be greatly lost, and the taste and taste of the vegetables will be greatly reduced.

Hot water scalding can greatly reduce the harm of pesticide residues in vegetables to the human body.

So, what are the pros and cons of pesticides for the human environment? The effect of "increasing production" is far from the environment. Benefits::

Pest control mainly refers to sanitary pests and rodents. Indirect control of the number of bacteria and toxins in the ambient air can sometimes compensate and save the ecological balance of the environment. Cons:

Irrational use will pollute the air and water sources, and the remaining contaminated food will be far away from the environment.

Always go to buy organic green vegetables, after buying back, you must wash them, wash them several times, it is best to scald them with hot water, and then you must cook them at high temperatures, so that you can eat them healthily.

Rice washing, salt water cleaning, soaking cleaning, alkaline water cleaning and other methods can be used to effectively remove pesticide residues. <>

1. How to clean vegetables to minimize pesticide residues in vegetables?

The soaking method is also able to remove pesticide residues, and in general, the purchased vegetables are put into pots. Add an appropriate amount of water to the pot, the water should be submerged with the vegetables, soak for 30 minutes or an hour, and then wash it continuously with running water 2 or 3 times to effectively remove it. However, this method is more suitable for cleaning spinach, leeks, lettuce, coriander, cabbage, etc.

Then rinse with running water 2 or 3 times, this method is more suitable for vegetables and fruits. <>

2. Conclusion. Rinsing with boiling water can also reduce pesticide residues in vegetables. Because high temperature can sterilize, blanching vegetables in boiling water for 1 3 minutes can make the surface of the pesticide inactive. This method is more suitable for celery, lettuce, spinach, etc.

Do not throw away the water used to wash rice, it can also be used to clean pesticide residues. Because the rice washing water is acidic, and the pesticide will lose its activity when it encounters acidic water quality, and it will be slowly decomposed. This can also be effectively removed, and cleaning with light salt water can also reduce pesticide residues.

Because there are some cabbage, cabbage, cabbage, etc., among these vegetables, the wrapping is relatively strong. Therefore, it is easier to hide dirt and dirt, and cleaning with light salt water can effectively remove some pesticides. However, after soaking, be sure to rinse with running water.

2. If it is a vegetable with more leaves, such as spinach, bok choy and so on. There are a lot of pesticide residues in this vegetable, and it is very easy to remain in the uneven gaps, so when you clean this kind of vegetables, you must first cut off the roots, and then wash off the mud on the vegetables, and then soak them in water for an hour or two before taking them out, and you can put a spoonful of baking soda in the water when soaking.

3. If it is a vegetable with flower buds, such as enoki, leek flowers, etc., the pesticides in such vegetables may remain in the flower buds, so when you wash them, soak them in salt water or alkaline water for an hour or two before eating.

4. For eggplant green pepper and pepper vegetables with a layer of wax on the outside, most of the pesticides are left on the skin, so you can use salt to scrub or wash with hot water when cleaning, which can effectively dissolve the wax on the surface.
