How to wash vegetables to minimize pesticide residues in vegetables?

Vegetables are indispensable in our daily life, and there are many nutrients in vegetables, many of which are also necessary for the human body. But now most of the vegetables on the market are very many pesticides, when you eat vegetables, if you don't clean it, it is inevitable that the pesticides will be eaten into the body, which is very bad for the body, so you must wash it when you wash the vegetables. Today, I will tell you how to clean vegetables to minimize pesticide residues in vegetables.

1. For vegetables with more gaps, such as corn, cauliflower, etc., most of the pesticides are left in the gaps, so it is best to blanch them with hot water when cleaning, and then take them out after the vegetables become soft, so that the pesticide residues in the vegetables can be well removed.

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.

5. If it is a vegetable with skin, such as radish, sweet potato, potato, cucumber, etc., the pesticides of these vegetables are attached to the skin, just peel off the skin and then wash it.

For everyone's health, you must not be sloppy when washing vegetables, and different cleaning methods should be adopted for different vegetables to prevent pesticide residues.

You can use light salt water to wash, soak the vegetables in salt water for about 5 minutes, and then rinse them with clean water, this cleaning method can effectively remove pesticides.

You can rinse vegetables with clean water many times, or there are many dish soaps on the market that specialize in cleaning vegetables, and this kind of cleaning agent can reduce pesticide residues in vegetables.

If you want to soak it in water for a while, you should also use a special detergent for cleaning, which is relatively safe.

It can be said unequivocally that the pesticides on the dish can not be cleaned. Some people say that it can be washed with vegetable washing liquid, but it can't be washed in this way. In the process of growing vegetables, under photosynthesis, pesticides have been soaked into the rhizomes of plants, and there are pesticides inside and outside the vegetables.

Vegetables are generally used low-toxicity pesticides, low-toxicity pesticides safety period is only seven days, after seven days will generally have insects, as long as a week after washing with water several times is basically fine, we grow our own food also spray, for fruits and vegetables that can be peeled. You can rinse with clean water first, then use a soft-bristled brush. Peel the fruit at the end so that dirty water does not contaminate the pulp.

In fact, our country's science and technology has developed to the point where a breath can detect drunk driving, a drop of blood can measure blood sugar, herbicides can make weeds die, crops grow normally, and baking soda can decompose the residual organophosphorus pesticides on the skin of fruits and vegetables. Don't forget to rinse off after soaking. Fourth, the heating method, some vegetables are washed and scalded in boiling water, then rinsed with water, and then cooked and eaten, high temperature to remove residues, there are some vegetables, such as celery, spinach, and many other kinds of vegetables, can be boiled with boiling water for a few minutes, so that the drug residue can be effectively removed.

Rinse. Rinse directly from the head to the root with clean water and live water (there are more pesticide residues in the roots) for more than 40 seconds, and rotate and scrub at the same time. After washing, cut off the thicker rhizome (the part that is not suitable for eating).

There's no other way to do it. Can it be removed: This pesticide residue can be washed, and most of the pesticide residues can be removed by soaking in salt water and rice washing water for flaky vegetables.

Fruits and vegetables can be peeled to remove pesticides completely. And this pesticide is exposed to the natural environment for a long time.

After soaking in baking soda, some pesticide residues can be removed. American studies have found that soaking vegetables in baking soda (soda, baking powder) can remove some pesticide residues. Method:

Rinse the surface of the vegetables first, then soak them in baking soda water (usually 5 10 grams of flour alkali are added to 500 ml of water) for 10 20 minutes, and then rinse with water.

Generally, pesticide residues are difficult to clean, but we can prepare some salt and water, which can have a certain cleaning effect, and we can also buy some professional products for cleaning pesticide residues.

1.Soak vegetables in water for a period of time, but this method can only eliminate some pesticides on the surface of vegetables, and it also needs to be combined with fruit and vegetable cleaning agents.

2.Heating fruits and vegetables to dissolve pesticides on their surfaces at high temperatures is suitable for fruits and vegetables where pesticides cannot be completely eliminated by other methods.

With the increase of temperature, the synthesis of carbamate insecticides accelerated. Therefore, some vegetables and fruits that are difficult to dispose of by other methods can be heated to remove local pesticides. It is often used in celery, spinach, bok choy, cabbage, green pepper, cauliflower, beans, etc.

The method is to wash the surface dirt with clean water, put it in boiling water for 2-5 minutes to remove it, and then rinse it with clean water 1-2 times.

How can pesticide residues in vegetables be reduced? What to look out for?

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.

To stay away from pesticide residues in vegetables, we must buy vegetables at ordinary times, try to choose vegetables that do not contain pesticide residues, you can try to go to some larger supermarkets, large supermarkets, often the purchase channel is ***, pesticide residues will be less, in addition, you can buy organic vegetables organic vegetables, that is, vegetables that are not sprayed with pesticides, in addition, if there are often some vegetable farmers around the place where they live pull their own vegetables out to sell, These vegetables are often free of pesticide residues, so as long as you are a caring person, you can buy fresh vegetables without pesticide residues.

Put the vegetables in cold water for soaking, the soaking time should reach more than half an hour, and rinse with running water, so that the residue of pesticides can be well reduced, and attention should be paid to the use of special vegetable detergent in this process, do not use dish soap.

Peel as much as possible, soak and clean it when eating, or place it at room temperature, and the pesticide will be eliminated after two or three days; Pay attention to cleaning when eating, you can also soak it in water under the faucet for scrubbing, it is best not to eat when it is not cleaned, it will cause harm to the body.

Washing vegetables with starch and salt can reduce pesticide residues in vegetables, and care should be taken not to wash vegetables with warm water.

In the process of washing vegetables, they should be washed several times, and they should also be boiled in boiling water to have a good effect. It should be noted that it must be cleaned several times.

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.

Pesticide residues in <> vegetables are an important issue in food safety. Especially in summer, it is not only the peak period of vegetable consumption, but also the active period of pests, producers in order to catch up with business opportunities, either use excessive concentration of pesticides to kill insects, or apply pesticides to harvest in advance, resulting in a large number of vegetable pesticide residues seriously exceeding the standard. According to statistics, under normal circumstances, the pass rate of pesticide residues in summer vegetables is more than 20% lower than that in winter.

In order to reduce pesticides on vegetables, people have come up with various methods: drying in the sun, blistering with water, washing with rice washing water, etc., but are these methods really effective, and how many pesticides can be removed? The College of Food Science at China Agricultural University recently conducted an experiment to help people figure out the best way to remove pesticides.

How to wash vegetables more cleanly? How to clean pesticides residues on vegetables.

Since pesticides are mainly attached to the surface of fruits and vegetables during the spraying process, as long as effective washing and processing methods are adopted, the residue of pesticides can be reduced and the food safety of vegetables can be ensured.

Soaking and scrubbing with water can reduce the amount of pesticide residues, and the longer the soaking time, the less pesticide residues. Experiments have proved that soaking vegetables in tap water for 10-60 minutes and then slightly scrubbing can remove 15-60 pesticide residues. Soaking in a special fruit and vegetable detergent is more effective in reducing pesticide adhesion.

The detergent is diluted with water at a ratio of 1 200 and then soaked in fruits and vegetables, and the pesticide residue can be reduced by 50 -80 within 10-60 minutes; Especially in the first 10 minutes of soaking, the pesticide residue drops very significantly, which can reach about 50. Then, with a little scrubbing and rinsing with clean water, the pesticide residue can be basically removed.

Pesticides can also be broken down by heating at high temperatures, such as blanching them in boiling water or stir-frying them in oil. Experiments have proved that some heat-resistant vegetables, such as cauliflower, beans, green peppers, celery, etc., can be washed and scalded with boiling water for a few minutes, which can reduce pesticide residues by about 30, and then cooked at high temperatures, 90% of the pesticides on vegetables can be removed.

In addition, washing vegetables with rice and washing vegetables and properly using sunlight can also play a certain role in reducing pesticides on vegetables. But it is best to use the first one or two rice water, because the surface of the rice contains potassium, so the first one or two rice washing water will be weakly acidic, but then it will begin to change to alkaline, and pesticides will only lose a certain toxicity in acidic substances. Sunlight exposure can cause some pesticides in vegetables to be decomposed and destroyed.

It has been determined that the residue loss of organochlorine and organic mercury pesticides can reach about 60 when vegetables are exposed to sunlight for 5 minutes.

Peeling vegetables can of course also reduce pesticide residues, but it also brings a loss of vitamins and minerals in the peel. Therefore, the best way to remove pesticides is to soak fresh fruits and vegetables in detergent for 10-15 minutes, or tap water for 30-60 minutes, rinse with water.
