How to remove pesticide residues when washing vegetables? What are the right ways to do it?

If you want to remove pesticide residues, soak them in water, wash them with salt, wash them with flour, beat them and blanch them。Food safety must be paid attention to, and if you want to eat safe vegetables, you must wash them thoroughly.

In order to control pests and diseases, vegetables will use pesticides in order to increase production. The vegetables we buy will have pesticide residues on them, and the vegetables should be carefully cleaned before making them. Pick the vegetables and soak them in clean water.

The soaking time can be longer so that pesticide residues can be removed from the vegetables.

Salt has a bactericidal effect, and salt can also remove pesticide products from the surface of vegetables. You can use salt to scrub the folds on the surface of the vegetables directly, or you can put some salt in the water, soak the vegetables in it, and then wash the vegetables carefully with clean water, the salt water can remove the pesticide residues on the vegetables.

Pesticide residues on vegetables cannot be avoided, in addition to soaking in water, cleaning with salt water, you can also use flour and water to clean the method. Put vegetables in clean water, sprinkle some flour on top of the vegetables, stir well, and soak for a while to effectively remove the dirt and pesticide residues on the vegetables.

The way we make vegetables is to peel as much as possible, because there are pesticide residues on the surface of vegetables. If the vegetables are peeled directly, pesticide residues can be effectively removed, such as tomatoes, eggplants, and cucumbers. All vegetables that can be peeled must be peeled, only then will they be safer to eat.

After washing the vegetables with clean water, you can put water in a pot to heat and blanch the greens. After blanching, the greens will be greener, which can retain nutrients well, and can also better remove pesticide residues on the surface of vegetables. In the process of blanching vegetables, you can add some cooking oil and salt, and the vegetables will lock in moisture and nutrients well.

There are also some skills in the process of selecting vegetables, and vegetables with more pesticides can be seen at a glance, so you should master more common sense of life and try to buy pure green and pollution-free vegetables.

We can soak the vegetables in lightly salted water for about an hour, and then rinse them with clean water, if the sun is good, we can put them under the sun to shine, and we can also use rice washing water or baking soda to wash them.

If it is a vegetable that can be peeled when washing vegetables, try to peel it so that the residual pesticides can be removed, and if it cannot be peeled, soak it in water and put in fruit and vegetable cleaning solution.

How to wash vegetables to effectively remove pesticide residues?

There are several measures to remove more than 95% of pesticide residues:

1.Soak in light salt water.

Generally, vegetables should be rinsed with water at least 3-6 times, then soaked in lightly salted water for 1 hour, and then rinsed with water once. For cabbage vegetables, you can cut them first, soak them in clean water for 2 hours, and then rinse them with water to remove residual pesticides.

2.Disinfect with sunlight.

Sunlight exposure to vegetables will decompose and destroy some of the pesticide residues in vegetables. It has been determined that the residue of organochlorine and organic mercury pesticides in vegetables and fruits exposed to sunlight for 5 minutes will be reduced by 60. Vegetables that are convenient for storage should be placed at room temperature for about two days, and the average disappearance rate of residual chemical pesticides is 5.

3.Wash with rice washing water.

Rice water is acidic, and organophosphorus pesticides will lose their toxicity when they encounter acidic substances. Soak in rice washing water for about 10 minutes and wash it with water to reduce the pesticide residue in vegetables. Found all over the country, it is a serious pest of cruciferous vegetables such as kale, cabbage, broccoli, cauliflower, romaine lettuce, etc.

Although the cabbage butterfly itself is harmless, the cabbage insect bites the leaves, and the wounds on the bitten leaves are easy to induce soft rot.

4.Wash with baking soda.

Put a teaspoon of alkali powder and sodium carbonate in the water, stir well, then add vegetables, soak for 5 to 6 minutes, and then rinse with water. You can also use baking soda instead, but extend the soaking time to about 15 minutes.

5.Blanch in boiling water.

When making green peppers, cauliflower, beans, celery, etc., it is best to blanch them with boiling water before putting them in the pot to remove 90% of the residual pesticides.

Common misunderstandings about washing vegetables:

1. Long-term soaking: sometimes there is a small amount of pesticide residues on the surface of fruits and vegetables, the main component is organic phosphorus (insoluble in water), soaking does not work, and it is easy to form "secondary pollution" for a long time, which may also lead to pesticide residues entering fruits and vegetables; It is not advisable to soak directly without rinsing, which will make some water-soluble pesticide residues dissolve and penetrate into the inside of fruits and vegetables, and with the extension of soaking time, the amount of pesticide residues in fruits and vegetables will show a trend of first decreasing and then rising (reaching the lowest after more than 10 minutes).

2. Washing rice water cleaning: edible rice itself also has problems such as pesticide residues and insect eggs.

3. Salt water cleaning: Salt will reduce the cleaning ability of water, which is not conducive to the cleaning of fruits and vegetables.

4. Cut vegetables first and then wash: it is easy to lose water-soluble vitamins in them, and it will also increase the chance of bacterial contamination on the surface of vegetables, leaving hidden health hazards.

The right way to clean:

1. For cucumbers, bitter gourds, carrots and other stems or melon vegetables, you can put the washing spirit and soak it in warm water for 1-2 minutes, scrub it with a soft brush, especially the depressions, rinse it with water after brushing, and peel and wash it if necessary;

2. For Chinese cabbage, cabbage and other leafy vegetables, you can remove the outer leaves, soak them in warm water inside, and then rinse them with water one by one.

3. Vegetables such as spinach and chrysanthemum can be cut off from the roots, shaken and cleaned in water, and then rinse the roots upwards in front of the faucet.

Other methods that help to remove pesticide residues: leave freshly picked vegetables in the air for 24 hours, some pesticide residues will decompose into harmless substances to the human body, and non-perishable vegetables such as winter melon can be properly placed for a period of time; In addition, through ultraviolet light, some pesticide residues can also be decomposed and inactivated; And beans, cauliflower and the like can be scalded with boiling water after cleaning.

Most mushrooms grow in moist soil, so it is easy for them to hide sediment in the folds of their umbrella-like parts, and if they are only washed with running water, not only will they not be clean, but the sand may also be hidden deeper and deeper.

Correct washing: Warm water should be used when washing, so that the folds of the mushroom can be slowly opened. You can add some flour to the water and stir it in one direction with your hands at the same time to make it easier for impurities such as sediment to fall out. Finally, rinse again with running water.

Cauliflower, broccoli.

Like mushrooms, cauliflower has dense spikes that make it easy to hide small insects and dirt, and it is difficult to wash them thoroughly with water.

Correct washing method: first gently scrub the surface of cauliflower and broccoli with a small brush, then break it into small florets and soak them in water for about 5 10 minutes. Finally, rinse again with water.

The cauliflower washed in this way is not only clean, but also easier to ripen when stir-fried, and tastes better.

Some people may feel that the cabbage leaves are tightly wrapped, only the outside is dirty, so when washing, just peel off the outer layers of leaves and rinse them with water.

However, when spraying pesticides, the liquid medicine may also enter the cabbage sum due to the effect of gravity and accumulate inside; And because the internal structure of cabbage is special, some small insects are easy to stay inside, so it is not enough to wash the outside.

Correct washing method: first cut a knife at the root of the cabbage at a position of 1 2 cm, let the leaves spread out naturally, and then break off the leaves one by one by hand, soak them in water for about 5 10 minutes, and finally rinse them with water.

In this way, the pesticide residues of vegetable washing do not decrease but increase, and the daily vegetable washing methods of cancer prevention experts should be learned quickly.

Correct washing method: remove the excess fat on the fat intestine first, then sprinkle with an appropriate amount of flour, knead vigorously, and then wash with water, this process can be repeated about 3 times. When scrubbing fat sausages, you can also drip some lemon juice, which can not only help remove excess oil, but also increase the fragrance of the fruit.

In this way, the pesticide residues of vegetable washing do not decrease but increase, and the daily vegetable washing methods of cancer prevention experts should be learned quickly.

Pork, beef and mutton. Rinsing raw meat directly with running water will not kill bacteria, and bacteria can contaminate sinks, chopping boards, kitchen knives and other objects through splashes, making it easier for it to spread.

Correct washing method: first put an appropriate amount of flour water in a basin, and then put the raw meat in it and soak it for about 5 minutes. After that, you can change the water and soak it again.

In addition, it is best not to use hot water when cleaning meat, otherwise it may accelerate the loss of some nutrients in the meat and also affect the taste.

Soak in water and wash several times.

For general vegetables, you can soak them in water for about 15 minutes, then scrub and scrub, and then brush them several times to remove some pesticide residues on the surface.

Wash vegetables with edible alkali or brine.

Use a small amount each time, and the soaking time should not exceed 20 minutes, and be sure to rinse well.

Let vegetables and fruits bask in the sun.

Relevant studies have proved that the spectral effect of sunlight and ultraviolet rays on vegetables will occur, which will decompose, inactivate and destroy some residual pesticides in vegetables. Therefore, letting vegetables bask in the sun can remove residual pesticides to a certain extent.

Leave it for a period of time to reduce pesticide residues.

Some pesticides slowly decompose over time into substances that are not harmful to humans during storage. Therefore, for those vegetables that can be stored for a long time, put them for 3-5 days after buying, and then wash them several times with alkaline noodles to eat, which can minimize pesticide residues.
