Vegetables and fruits are seriously overloaded with pesticides, how to clean them

Peeling method, vegetables and fruits that can be peeled, try to peel as much as possible, such as melons and vegetables, but will lose the nutrients in the skin.

Soak in light salt water. Generally, vegetables and fruits should be rinsed with water at least 3 to 6 times, then soaked in lightly salted water, and rinsed with water again. Vegetables can be cut open, soaked in water for 1 to 2 hours, and then rinsed with water to remove residual pesticides.

Alkaline water soaking. Put a pinch of alkali powder in the water first, anhydrous calcium carbonate, glacial alkali or crystalline sodium carbonate, stir well, and then add vegetables. After soaking for 5 to 6 minutes, pour out the alkaline water and rinse it off with clean water.

Baking soda can also be used instead, but the soaking time needs to be extended appropriately, generally about 15 minutes.

Blanch in boiling water. The best way to remove pesticide residues is to blanch, such as green peppers, cauliflower, beans, celery, etc., and it is best to blanch them with boiling water before putting them in the pot. According to the test, this method can remove 90% of the residual pesticides.

Daylight. After vegetables are exposed to sunlight, a multispectral effect will occur, and some residual pesticides in vegetables will be decomposed and destroyed. It has been determined that the residue of organochlorine and organic mercury pesticides can be reduced by 60% when vegetables and fruits are exposed to sunlight for 5 minutes.

Because the oxygen in the air and the chromase in vegetables have a certain decomposition effect on residual pesticides, after purchasing vegetables, they should be placed at room temperature for about 24 hours, so that the average disappearance rate of residual pesticides is 5%.

Soak in rice water. Because most of the current organophosphorus pesticides are used to kill insects, these pesticides will lose their toxicity when they encounter acidic substances, so the vegetables are soaked in rice washing water for about 10 minutes and then washed with water, which can reduce the residual pesticides.

1. Water soaking washing method: first rinse off the surface dirt of vegetables with water, and then soak them in water, but the soaking time is best not less than 10 minutes. In this way, most of the residual pesticide components can be removed after washing and soaking twice.

2. Add auxiliary agent soaking washing method: you can add alkali (small soda), fruit and vegetable cleaning agent, and rice washing water (preferably the first two times) for soaking and washing. Soaking fruits and vegetables in such water for 5 to 15 minutes can remove organophosphorus pesticides from the surface of fruits and vegetables.

After soaking, be careful to rinse thoroughly.

3. Storage method: The oxygen in the air has the effect of decomposing some pesticides, so some easy-to-keep vegetables and fruits can be reduced by extending the storage time. For example, non-perishable vegetables such as winter squash and pumpkin can be left for more than 3 days before eating.

4. Heating method: The decomposition of some pesticides will accelerate with the increase of temperature, so it can also help remove pesticide residues. For example, green peppers, beans, celery, snow peas, etc., can be washed with water first, then put in boiling water and boil for 2 to 4 minutes, and then rinse with water 1 to 2 times.

5. Peeling method: This is the most effective method, but it is only suitable for those vegetables with skin. For example, cucumbers, carrots, pumpkins, apples, etc., can be peeled directly with a peeler containing residual pesticides.

Wash with detergent or soak in water for a long time.

You can soak the fruits and vegetables in lightly salted water for about 30 minutes. Then wash it with water several times to clean most of the residual pesticides.

But rinse with clean water, directly turn on the faucet to flush for a while, and then soak the fruit in a pot for a while or soak for about an hour or two, and the bacteria and pesticide residues in it will be much less.

It can be cleaned by soaking in alkaline water. You can add 5-10g of edible alkali to clean water to prepare alkaline water, and then soak the fruit in the made alkaline water.

Vegetables and fruits will use some pesticides in the process of planting, so this will have a certain impact on our health, so, after we buy these vegetables and fruits home, what should we do to wash off the pesticide residues on these vegetables and fruits? Check it out with this guide!

01 Soak in baking soda.

Whether it is a fruit or a vegetable, after cleaning, you can add water to the basin, then add baking soda powder appropriately, soak it in, and rinse it again with water after half an hour.

02 Flour.

For example, when cleaning apples, tomatoes and other fruits, you can use flour to remove pesticide residues, soak the fruits, sprinkle flour on the fruits, and then scrub them one by one, so that the pesticide residues on them will be taken away by the flour.

03 Salt.

After the fruits and vegetables are cleaned, the salt is poured into the water to dissolve them, and after dissolving, the fruits and vegetables are soaked and soaked for a period of time, which can also have the effect of removing pesticide residues.

04 Rice water.

It's also a good way to wash off pesticide residues in fruits and vegetables, soak them in rice washing water for half an hour, and then rinse them off again.

1. Soak with baking soda. Whether it is a fruit or a vegetable, after washing, we can add water to the basin, then add baking soda appropriately, soak in it, and generally rinse it with water after half an hour. When washing apples, tomatoes, and other fruits, flour can also be used to remove pesticide residues.

After the fruit is soaked, the flour is sprinkled on the fruit and then washed one by one so that the pesticide residues on the fruit are carried away by the flour.

2. The method of using salt. Once the fruits and vegetables are clean, pour the salt into the water to dissolve. After dissolving, soaking the fruit and sugar cube for a period of time can also remove pesticide residues.

Wash the fruit with water 2-3 times, then soak it in lightly salted water for half an hour, and then wash it with water to remove residual grapes, strawberries, peaches and other agricultural products.

3. Use storage methods. During long-term storage, pesticides slowly break down into harmless substances. Some fruits that are easy to preserve can be used for a period of time before eating, and the pesticide residue will become less and less, and then they can be washed and eaten.

Such as: apples, kiwifruit, pomegranates and other fruits that are easy to store. Soak the fruit in the rice washing water for about 10 minutes, and then rinse it with clean water to reduce the pesticide residue on the fruit.

Fruits are highly nutritious and loved by many people! But, do you know how to wash fruit to wash it clean?

Many people think that washing fruit is a very simple thing, and some people think that it is a very troublesome thing.

Wash with water, for fear that there will be pesticide residues; Wash with dish soap, but you are afraid that it will not be clean; I feel that it is too troublesome to clean with a special fruit and vegetable detergent......

How do you clean it? In fact, if the cleaning method is not correct, it may get dirtier and dirtier the more you wash it

A picture shows you some common ways to clean fruits. Borrow some daily necessities and food, and the fruits can be washed clean and safe.

Apples, peaches, pears

You can soak the fruit bubble in soda water for 5 minutes to remove pesticide residues, glue and other stains on the peel.

If you don't have soda water at home, you can rub the peel with salt grains before washing it with clean water.

Grapes, cherries

There is a lot of residue on the peel, and it can be cleaned by the method of starch water adhering to the stain.

Bayberry

It is easy to hide the eggs, and can be blistered with salt water.

For peeled fruits such as mangoes and oranges, wash them before cutting them.

For fruits eaten with the skin, you need to use salt, flour and other items.

Washing water washing method

Rice washing water is alkaline, decomposable pesticide residues and viscous, can adsorb chemicals on the surface of fruits, and can wash granular fruits such as strawberries and mulberries.

Lemon cleaning method

Spray the lemon juice on top of the fruit and let it stand for about a minute to wipe off, removing pesticide residues and leaving the lemon fragrance.

Flour washing method

The starch is viscous and can adsorb fruit residues, making it suitable for cleaning grape citrus fruits.

Salt water cleaning method

The pesticide residues of some fruits are acidic, some are alkaline, it is better to soak them in salt water, and you can also use salt grains to remove the fine hairs of the fruit skin.

Baking soda cleaning method

Baking soda has alkaline properties to neutralize pesticide residues on the surface of fruits, add 2 spoons of baking soda powder with a basin of water, soak the fruit in a prepared solution, and wash cherries, dates, etc.

It should be reminded here that it has been popular to use rice washing water to clean fruits and vegetables in the past, but as everyone knows, eating rice also has the problem of pesticides and insect egg residues.

In addition, there is usually only one pot of rice washing water, and the amount of water is not enough to wash away pesticides, and the vegetables are soaked in it, and a pot of rice washing water becomes a pesticide pool, which is dirtier than unwashed vegetables.

Vegetables and fruits in the process of growing.

Pesticides are usually applied to prevent pests, so how do you remove pesticide residues from vegetables and fruits?

01 Immersion washing method.

Generally, the surface dirt is rinsed off with clean water first, and then soaked in water for 20-30 minutes. When soaking, you can add a small amount of fruit and vegetable cleaning agent, and then rinse it with running water two or three times after soaking. It is suitable for all kinds of leafy vegetables, such as spinach, goldenrod, leek, lettuce, coriander, bok choy, etc.

02 Alkaline water immersion cleaning method.

Keep a bottle of baking soda in your home kitchen. The pesticides used in China are mainly organophosphorus, and organophosphorus pesticides will quickly decompose and fail in an alkaline environment. Rinse the surface dirt first, soak it in baking soda alkali water (generally add 5 grams to baking soda to 500ml of water) for about 15 minutes, and then rinse with water 3-5 times.

Applicable fruits and vegetables: all kinds of vegetables and fruits.

03 Blanching cleaning method with boiling water.

Some pesticides on vegetables can be ineffective by heating them, boiling them in boiling water for 1-3 minutes, and then washing them. Such as spinach, lettuce, coriander, kale, celery, peppers, zucchini and other vegetables.

04 Rice washing water immersion cleaning method.

Rice water is acidic, and the pesticides left on the vegetables will slowly decompose and become ineffective when they encounter acidic rice water.

05 Salt water cleaning method.

Washing vegetables with 1%-3% light salt water can not only remove some pesticides, but also remove various small insects hiding in the root area or the back of the leaf. Such as Chinese cabbage, cabbage, cabbage and other vegetables.

06 Clear water baking soda flour removal method.

For grapes, cherries, cherries and other fruits, first rinse the dirt on the surface of the fruit, add some flour to baking soda alkali water (generally 500ml of water to add 5 grams of baking soda to 10 grams) to improve the viscosity of the water, soak for about 15 minutes, and then rinse with water 3-5 times.

07 Peeling method.

The amount of pesticides on the surface of vegetables, melons and fruits is relatively large, and peeling is a better, simple and practical method to remove residual pesticides. Applicable fruits and vegetables: apples, pears, kiwifruit, cucumbers, loofahs, winter melons, pumpkins, zucchini, eggplants, carrots, radish, potatoes, etc.

08 Storage method.

During the storage of vegetables, the oxygen in the air and the enzymes in the vegetables and other active substances can react with the residual pesticides, so that the pesticides can be oxidized and degraded, which can reduce the amount of pesticide residues and reduce their toxicity. Therefore, fruits and vegetables that are easy to preserve can be stored for a certain period of time to reduce the amount of pesticide residues. It is suitable for non-perishable species such as apples, kiwifruit, and winter melons.

09 Drying method.

The spectral effect will decompose and destroy some of the residual pesticides in vegetables. Vegetables exposed to sunlight have less pesticide residues. For vegetables that are convenient for storage, it is best to leave them for a few days, and the oxygen in the air and the chromoenzymes in the vegetables have a certain decomposition effect on the residual pesticides.

Suitable for cabbage, cabbage, cabbage, etc.

(1) Water soaking washing method.

It is mainly used for leafy vegetables, such as spinach, lettuce, bok choy, etc. Generally, rinse off the surface dirt with clean water, remove the visible stains, and then cover the fruits and vegetables with water about 5 cm, and soak in running water for no less than 30 minutes. If necessary, cleaning agents such as fruit and vegetable lotions can be added to increase the dissolution of pesticides.

Soak it in this way for 2 or 3 times, which can basically remove most of the residual pesticide components.

2) Alkaline water immersion cleaning method.

Most organophosphorus insecticides decompose rapidly in an alkaline environment. Generally, 5 10 grams of edible alkali are added to 500 ml of water to prepare alkaline water, and the fruits and vegetables after preliminary rinsing are placed in alkaline water, according to the amount of vegetables, sufficient alkaline water, soaked for 5 15 minutes, rinse fruits and vegetables with water, and repeat washing about 3 times The effect is better.

3) Heat cooking.

It is often used in celery, cabbage, green peppers, beans, etc. Because carbamate insecticides will accelerate their decomposition with the increase of temperature, the washed fruits and vegetables are generally placed in boiling water for 2 5 minutes and then removed immediately, and then washed with water 1 or 2 times, and then placed in a pot to cook into dishes.

4) Cleaning and peeling method.

For fruits and vegetables with skin, the appearance of pesticide residues can be peeled off with a sharp object, and the fleshy part can be eaten, which is both delicious and safe.

5) Storage-custody law.

Some pesticides slowly decompose over time into substances that are not harmful to humans during storage. Therefore, when conditions permit, some fruits suitable for storage should be purchased and stored for a period of time (10 to 15 days). Wash and peel before eating for better results.
