Can pesticides on fruits and vegetables be removed by soaking for half an hour?

Pesticides on fruits and vegetables can be soaked in tap water for 10-60 minutes and then slightly scrubbed, 15%-60% of pesticide residues can be removed, but they cannot be completely removed. Soaking in a special fruit and vegetable detergent is more effective in reducing pesticide adhesion.

In the process of spraying, pesticides are mainly attached to the surface of fruits and vegetables, so 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 guaranteed.

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 15%-60% of pesticide residues can be removed by soaking vegetables in tap water for 10-60 minutes and then slightly scrubbing. 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, green peppers, etc., can reduce pesticide residues by about 30% after washing and then scalding with boiling water for a few minutes, and then 90% of pesticides on vegetables can be removed by cooking at high temperatures.

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.

The method of soaking pesticides on fruits and vegetables can reduce the residue, but the time of soaking is the main! Generally, it is enough to soak for a few minutes, and it must not be too long; Over time, pesticides that have been dissolved into water will be absorbed into the plant by biological cells, thus having a counterproductive effect!

For most of us, the quality of our life is getting higher and better. And we will also pay great attention to this aspect of diet, some people will have such doubts, that is, can the vegetables that have just been bought soaked in water remove the residual pesticides? In my personal opinion, I actually think it's okay, and we can also add some salt to the water, so let's take a closer look.

1 Absolutely

Now for most people, in fact, many times we buy things outside, some vegetables are unhealthy, because in this process, they are also pesticides, because when vegetables are growing, they will also suffer from a lot of pests and diseases, so if they are sown with pesticides, you can alleviate the phenomenon of the state, but when we buy such similar vegetables, we must soak it in water, and at the same time, we must wash it several times before we can remove those pesticides inside.

2 Put salt in the water

I believe that everyone has a certain understanding of the salt we eat, and we all know that if you put it in water and dissolve it with water, then you can wash vegetables with such a solution, it can have a disinfection effect, which is what we call salt water.

Therefore, we should pay more attention to this aspect of the problem in our daily life, for everyone, understanding this aspect of the problem, we have a certain benefit, and now we are in such an era, in fact, many times we buy outside things are unhealthy. So after we buy it, we have to clean it before we can use it. I believe we have all heard the saying that illness comes from the mouth, and disaster comes from the mouth, and if what we eat is unhealthy or stale food, then it is likely to endanger our health.

Soaking in water is not to remove residual pesticides, it is best to choose some fruit and vegetable cleaners or soak them in salt for 20 minutes.

Soaking the vegetables you just bought in water will not remove the residual pesticides, and you will need to wash them several times and disinfect them.

There are more or less pesticide residues in the vegetables you have just bought, you can soak them in water first, and then wash the vegetables under running water to minimize the pesticide residues. Secondly, there is another way to soak in rice washing water or alkaline water, soak for about ten minutes, and then rinse with running water, which has a degrading effect on pesticide residues. It is recommended to eat more fresh fruits and vegetables every day, wash vegetables before eating, and eat a diversified diet to strengthen nutritional intake and avoid malnutrition.

Proper exercise after meals can enhance one's own resistance and immunity.

Soaking the purchased vegetables in clean water for 30 minutes can eliminate pesticide residues.

Vegetables are generally soaked in water for 30 minutes, and then slightly scrubbed can play a good role in removing pesticide residues. If a special fruit and vegetable detergent is used, the soaking time can be controlled to about 20 minutes, and finally the mold residue can be rinsed with warm water to remove pesticide residues.

Soak fresh fruits and vegetables in detergent for 10 to 15 minutes, or tap water for 30 minutes, rinse with water. If the skin needs to be peeled, direct peeling can effectively remove more pesticide residues.

Vegetables are sure how to clean

1. If you want to remove the residual pesticides on the vegetables as much as possible, you can use a soft brush to scrub them. For example, to clean cucumbers, green peppers, carrots, bitter gourds and other stems and melon vegetables, you can add detergent to the water, soak in warm water for 1-2 minutes, and then scrub with a soft brush, especially the depressions, brush a few more times, and then rinse with water.

2. For Chinese cabbage, cabbage and other leafy vegetables, the peripheral leaves can be removed, and the inner leaves can be soaked in warm water and then rinsed with running water one by one. Vegetables such as beans and cauliflower can be scalded with boiling water after washing, which can also remove the residual pesticides.

3. In addition to brushing, long-term storage, ultraviolet light and other methods can also remove residual pesticides in vegetables. Some freshly picked vegetables are left in the air for 24 hours in advance, and the residual pesticides can be broken down into harmless substances to the human body.

Soak the vegetables in clean water for 30 minutes, repeat two to three times to remove pesticides, or soak them in alkaline water for about 5-15 minutes, and then wash them repeatedly with water.

Vegetables are indispensable food in daily life, when planting vegetables, in order to avoid insects, planters will spray a large number of pesticides on vegetables, resulting in pesticide residues on vegetables, and pesticide residues on many vegetables are seriously exceeded.

If you eat this kind of vegetable, not only can not supplement the nutrients needed by the human body, but also affect your health, so before cooking, you must clean the pesticide residues on the vegetables, so as to avoid excessive pesticide intake and ensure health.

Soaking in water can remove pesticide residues, but this method takes a long time, if you want to remove pesticides quickly, you can use hot water, clean the vegetables and soak them in hot water for 2-5 minutes and then take them out, this method is suitable for celery, spinach, green peppers, cauliflower, beans, etc.

Many vegetables are not easy to perish, such as winter melon, pumpkin, etc., after buying this vegetable, you can store it for more than a week before eating, and the pesticides on the vegetables will gradually decompose over time.

There is a detergent for cleaning vegetables on the market, this detergent adds ingredients that can remove pesticide residues, which is harmless to the human body, and when cleaning vegetables, you can also use a special detergent, which is simple and effective.
