How to quickly remove pesticide residues? How to remove pesticide residues

Social and economic development is getting faster and faster, people are more and more concerned about their own health, many people will be concerned about a problem when eating, that is, pesticide residues, so for our health, we must do a good job of pesticide removal, so that we can make our lives better, at the same time, we need to pay attention to,For some fruits and vegetables, peeling is the simplest and crudest way to remove pesticide residuesFor apples, pears, cucumbers, eggplants, radishes, etc. are very good, I hope everyone can know about this, and we need to pay attention to food hygiene in daily life.

1. What impact will pesticide residues have on our lives?

We all know that pesticides will have a certain impact on the function of the human body if ingested into the human body, so we must pay attention to the removal of pesticide residues, only in this way will not affect our lives, and we need to pay attention to the fact that for some vegetables and fruits in life, we must buy from regular supermarkets, and roadside stalls must stay away.

2. What are the methods to remove pesticide residues?

Generally speaking, soaking in water has a very good removal method for green foods such as vegetable leaves, but we need to pay attention to the fact that for pesticide removal, the surface of the dirt is generally washed off with running water, and then soaked in water for more than 5 minutes to achieve the removal effect, I hope everyone can know this, but we need to pay attention to the fact that there are certain drawbacks in removing pesticides with clean water.

3. What other methods can remove pesticide residues?

We all know that for fruits such as apples and pears, pesticides can be slowly decomposed with the extension of storage time, so we can use some shelf-stable bone combs for a period of time, which can better protect our health, and we can also remove pesticides through scientific and technological means, because we all know that there is an ultrasonic fruit and vegetable cleaning machine on the market now, which is still very easy to use.

Fruits and vegetables can be peeled off, soaked in salt water, or washed with baking soda, all of which can remove pesticide residues.

Use clean water to wash and add professional dish soap to quickly remove the pesticide residues on it, and it will be relatively clean.

You can spray some water on the leaves in time, you should also irrigate in time, and you should open the windows for ventilation in time, and be sure to wash them with fruit and vegetable cleaners when eating.

Answer: (1) Running water rinsing plus soaking method. The main pesticides used to contaminate vegetables are organophosphorus insecticides.

Organophosphate insecticides are insoluble in water, and this method can only partially remove pesticide contamination. 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, bok choy, etc. Generally, the surface dirt is rinsed off repeatedly with water, then soaked in water for 15 minutes, and then rinsed with running water two or three times.

Fruit and vegetable cleaning agent can increase the dissolution of pesticides, and a small amount of fruit and vegetable cleaning agent can be added when rinsing.

2) Running water rinsing and alkaline water immersion method. Organophosphate insecticides decompose rapidly in an alkaline environment, so this method is an effective measure to remove pesticide contamination. It can be used for all kinds of vegetables and fruits.

The method is to rinse the surface dirt first, soak it in alkaline water (generally add 5 to 10 grams of alkaline surface to 500 ml of water) for 5 to 15 minutes, and then rinse with water 3 to 5 times.

3) Peeling method. The amount of pesticides on the surface of vegetables and fruits is relatively large, so peeling is a better way to remove residual pesticides. It can be used for apples, pears, kiwis, cucumbers, carrots, winter melons, pumpkins, zucchini, eggplants, turnips, etc.

4) Storage method. During storage, pesticides can be slowly decomposed into substances that are harmless to humans. For fruits and vegetables that are easy to preserve, they can be stored for a certain period of time with less pesticide residues.

It is suitable for non-perishable species such as pumpkin and winter melon. Generally, it is stored for more than 15 days. At the same time, it is recommended not to eat freshly picked, unpeeled fruits and vegetables immediately.

5) Heating method. 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 to remove it, and then wash it once or twice with clean water.

1. Rinse and soak in water

Most pesticides are acidic, and most pesticides can be removed with slightly alkaline rice washing water and detergents. How to remove pesticide residuesNote that during the washing process, do not knead the vegetable leaves, so as not to cause secondary pollution of the inside of the vegetable leaves.

Since most pesticides are water-soluble and mostly attached to the surface of vegetables, as long as they are cleaned well, the pesticides on the surface can be washed off. Usually the surface is washed with water before soaking (no less than 10 minutes). Repeat this procedure 2 to 3 times, and most of the pesticides can be removed.

2. Peel off the outer leaves:

The outermost leaves of many vegetables have the most pesticides attached to them, especially the leafy vegetables of Chinese cabbage and cabbage, and the outermost leaves can be peeled off to avoid the risk of eating pesticides.

3. Blanch with hot water:

For some vegetables that are difficult to remove pesticide residues, such as celery, cabbage, green peppers, cowpeas, etc., before getting out of the pot, you can wash the surface with clean water, blanch it in boiling water for 2 5 minutes, and then rinse it with water 1 2 times to remove 90% of the residual poison. How to remove pesticide residuesMost of the pesticides dissolved in oil will not penetrate into the inside of vegetables, as long as the skin of the vegetables is thickly peeled off, and then scalded with hot water, the pesticides or residues can be dissolved.

4. Peel and clean:

Skinned'Vegetables, such as cucumbers, carrots, winter melons, pumpkins, eggplants, etc., can be peeled off and then washed with water, which is the easiest way to remove pesticides.

5. Wash after adding salt

If you still feel uneasy about cucumber vegetables after washing, you can put them on the cutting board and add salt, gently turn the cucumber on the cutting board with your hands, and then wash off the salt with water to dissolve the insecticide that has penetrated into the skin of the cucumber.

I checked the following practices, and I don't know if it helps you.

1 Washing. Thorough washing of vegetables is the most direct and effective way to remove pesticides. Rinse the vegetables under tap water for more than 30 seconds, and with scrubbing, most of the residual pesticides will be removed.

Cleaning. 2 Peel.

For tubers and fruit vegetables, even if there are pesticide residues, they are mainly distributed in the epidermis, so peeling is an efficient means of removing pesticide residues. If you feel that eating the skin is nutritious, then as long as the vegetables are fully washed, there are few pesticide residues on the skin, and you can eat it with confidence.

Shelling. 3 Heating.

Pesticide decomposition is a chemical reaction, and the speed of the chemical reaction is greatly affected by temperature, so as long as the vegetables are fully heated, the pesticide degradation will be promoted. However, some degradation products are harmless, and some may be harmful, so blanching is a better choice. Blanch the vegetables and then take them out, so that the removal of pesticides is efficient and the damage to nutrients is relatively small, which is suitable for most vegetables.

Heating. 4 Soak in salt water.

Soaking vegetables in lightly salted water can increase the solubility of pesticides left on vegetables to a certain extent, but the effect is limited and affects the flavor of food. If the concentration of brine is too high or the soaking time is too long, reverse osmosis is also prone to occur, and pesticides will penetrate into the inside.

The best way to remove pesticide residues is to wash, blanch and peel.

1 Washing.

The method of running water flushing and external friction has a certain effect on the water-soluble pesticides attached to the surface of fruits and vegetables, and friction can remove the fruit wax on the surface, and the nutrients are kept relatively intact.

It was found that the mechanical movement during cleaning plays a key role in the removal of pesticides, but has little to do with the solubility of pesticides. Therefore, when we do not know the type of pesticide residue in vegetables, it is recommended to wash with running water and gently scrub at the same time for better results.

2. Blanching:

High-temperature heating can decompose pesticides, blanching can remove about 80% of pesticide residues, especially spinach, cabbage, rape, cabbage, cabbage and other leafy vegetables, and beans, celery, cauliflower, etc. can be scalded with boiling water for a few minutes to reduce pesticide residues by 30%.

3. Peeling:

Most pesticides are generally left on the skin of vegetables and fruits, and cucumbers, carrots, apples, pears, etc. are best peeled and eaten.

It is relatively safer to eat without the skin, but it also loses some nutrients, especially dietary fiber and some vitamins and minerals, which are generally abundant in the pulp and near the skin. Many pesticides are unstable, and residual pesticides will decompose over time.

How to pick fruits and vegetables with less pesticide residues

1. Try to buy fruits and vegetables that are abundant in the season. Vegetables and fruits that are out of season need to be sprayed with a large amount of pesticides, which is more likely to cause pesticide residues.

2. Do not choose vegetables and fruits with special appearances. For example, the top of the tomato is pointed, which is caused by the vegetable farmer's spraying of hormones to promote growth, fertilizer and ripening, and this kind of vegetables and fruits cannot be eaten.

3. Eat fruits and vegetables with bagging protection. Such fruits and vegetables have less adhesion, such as grapes, star fruit, etc. Do not choose fruits and vegetables that have drug spots or smell of chemicals.

Most pesticides are insoluble in water, and residual pesticides are generally concentrated in the skin of vegetables and fruits

1. Soak and wash method. Most pesticides are insoluble in water, and this method can only remove a very small amount of pesticide contamination. Secondly, water washing will cause water pollution and form secondary pollution of pesticide residues.

2. Alkaline water immersion method. This method can only remove a very small amount of pesticide residues, which will also cause secondary pollution. It is harmful to some soluble pesticides.

Soluble pesticides may react chemically with alkalis, making pesticides more toxic, for example, trichlorfon can become more toxic dichlorvos in alkaline solution.

3) Peeling method. The limitation of this method is that it can only remove pesticide residues on the surface of some melons and fruits, but there is no way to remove more vegetables. After peeling, the nutrients in the peel are also removed. Similarly, the removed skin will cause further environmental pollution when it enters the environment.

Wash and soak 2

3 times, basically can remove most of the residual pesticide components.

2.Alkaline water immersion cleaning method: Most organophosphorus insecticides can decompose quickly in an alkaline environment. It is generally added in 500 ml of water.

The easiest way is to soak it in water for half an hour, cooked food is the best and most effective.

For the removal of pesticide residues, water is used daily to remove pesticide residues for vegetables and fruits. Basically, it is partially removed from pesticide residues, but it does not achieve an efficient effect.

The surface of fruits and vegetables can be washed and soaked for 1 minute, and the active oxygen under a safe concentration can be dissolved into water after electrolysis, which can achieve efficient removal of pesticide residues and the sterilization efficiency can be as high as above.

At present, the most popular and effective method of removing pesticide residues on the market is to use smart sink cleaning, taking Kang World as an example, the original high-efficiency inverter technology can strip pesticide residues into water, not only that, but also remove meat blood stains and grease, seafood sediment parasites.

1. Soak the fruits and vegetables in tap water for 10 to 60 minutes, and then scrub them slightly

It can remove 15% and 60% of pesticide DU residues. However, yes

For fruits and vegetables with wax on the surface such as eggplant, green pepper and water fruit, it is best to soak them first and then wash them.

2. Cutting vegetables into small pieces and soaking them will cause pesticides to seep in, the best way is to keep the vegetables and fruits intact and rinse them with running water. You can also soak it in light salt water or rice washing water for the first time or two, the former will dissolve the pesticide quickly, and the latter will neutralize the pesticide toxicity, but do not soak it for too long.

3. Sunlight exposure can decompose and destroy some pesticides in vegetables. It has been determined that the residue of organochlorine and organic mercury pesticides can be reduced by about 60% when vegetables are exposed to sunlight for 5 minutes.

4. High-temperature heating can also decompose pesticides, such as scalding with boiling water or stir-frying in hot oil. Experiments have proved that some heat-resistant vegetables, such as cauliflower, beans, celery, etc., can reduce pesticide residues by 30% after washing and then scalding with boiling water for a few minutes, and then 90% of pesticides can be removed by cooking at high temperature.

5. Although peeling vegetables will cause a certain amount of nutrient loss, it can reduce pesticide residues. In particular, cucumbers, eggplants and other vegetables that use a lot of pesticides and most fruits are best eaten by peeling.

6. When eating apples, it is best to eat less around the pit, because the gaps in the pit will cause pesticides to seep in.

Teach you how to remove pesticide residues.

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.

Since the pesticide components are mainly acidic, so when washing vegetables, add edible alkali appropriately, soak for five or six minutes (don't soak for too long), and then rinse with water. For vegetables with thick peels, they can be washed with salt water, which has a good effect on removing pesticides.

Blanch the vegetables in hot water.

For cauliflower, celery, green peppers, beans and other vegetables, they can be blanched in hot water before eating, and then washed once or twice, which can accelerate the decomposition of carbamate insecticides with the increase of temperature, so as to effectively remove pesticide residues. Be careful not to blanch too much with hot water, which can easily destroy the nutrients in the vegetables.

Peel to remove pesticide residues.

For root vegetables, peeling is a better way to remove residual pesticides, because the appearance is uneven or hairy melons and fruits on the surface of the pesticide is relatively more, such as winter melon, apple, pear, cucumber, etc., therefore, before eating, you can peel as much as possible to eat, but it should be noted that you must first clean and then peel, so as to avoid the pesticide contamination of vegetables and fruits on the leather knife.

Use fruit and vegetable detergents appropriately.

Now some meal washing, fruit and vegetable detergents are advertised to be effective in removing pesticide residues in vegetables and fruits, many people want to use it frequently, but experts believe that the so-called fruit and vegetable detergent can only play a certain role, if used too much or too frequently, it will cause secondary pollution, so it should be used carefully. 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, they can be stored for 3-5 days after buying, and then washed and eaten several times with alkaline noodles, which can minimize pesticide residues.
