How to remove pesticides and other harmful substances from fruits that can be eaten

In fact, for other vegetables, I personally do not approve of the use of brine soaking, which will damage the wrong taste and nutrition, and did not find a theoretical basis for brine to know pesticides, of course, it is not that there is not, it may be theoretically said that brine can also find a little reason to have an impact on pesticides, but I doubt that these are in the negligible category in practice. I don't know which magazine or TV introduced this "widely circulated" method, but I would love to see the original explanation of this problem, especially the relevant data in practice.

I'm sorry I still can't get your question right, because in fact, there is really no perfect method, and in fact, many netizens know that some methods for similar problems are actually good, you can use detergent, but you must rinse the detergent, especially the small two mouthfuls that have no offspring (hehe), as for the use of alkaline solution for some vegetables, although I have not seen the relevant data for household use, but there is a basis in theory, The key is that this basis is for one or several major categories of pesticides rather than one agent, so there may be a certain feasibility, but we should be cautious, because there may also be certain risks, and it may not be better not to use them.

Note that it is best to rinse with running water at the end.

Get your mindset right and develop good buying habits.

(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.

What should I do if I am afraid of pesticides when I buy fruits? Teach you a trick today to remove pesticide residues!

Wash the fruit with water first, then pour out the water, sprinkle a handful of flour to wrap on the surface of the fruit, rub the fruit with your hands, the flour is fully in contact with the surface of the fruit, the wet flour has a great stickiness, the pesticide residues on the surface of the fruit stick off, and then rinse it with water.

3. Soak in salt water: first wash the fruit with water 2-3 times, then drain it into light salt water and soak it for half an hour, and then rinse it with water to remove the residual pesticides. Such as: grapes, strawberries, peaches, etc.

4. Alkaline water immersion method: rinse the surface dirt, soak it in alkaline water for 15 minutes, and then rinse it with clean water.

5. Storage method: pesticides can be slowly decomposed into harmless substances in the process of long-term storage. Some fruits that are easy to preserve can be left for a period of time before eating, and the pesticide residue will be less and more, and then cleaned and eaten.

Such as: apples, kiwifruit, pomegranates and other fruits that are easy to store.

There are several simple ways to remove pesticide residues from vegetables and fruits at home:

Soaking and washing method: the pesticide varieties polluted by vegetables are mainly organophosphorus insecticides, which are insoluble in water, and this method can only remove part of the polluted pesticides. 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, cabbage, etc.

Generally, the surface dirt is rinsed off with water, and then soaked in water for no less than a minute. Fruit and vegetable cleaning agent can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaning agent can be added when soaking. After soaking, rinse with running water two or three times.

Alkaline water immersion method: Organophosphorus insecticides decompose quickly 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 alkaline noodles to grams in milliliters of water) for a minute, and then rinse it with clean water.

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.

Storage method: Pesticides can be slowly decomposed into harmless substances over time during storage. Therefore, fruits and vegetables that are easy to preserve can be stored for a certain period of time with less pesticide residues.

It is suitable for non-perishable species such as apples, kiwifruit, and winter melons. Generally stored for more than a few days. At the same time, it is advisable not to consume freshly picked unpeeled fruits immediately.

Heating method: Carbamate insecticides can 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 first, put it in boiling water for a minute to remove it, and then wash it with clean water.

One or two times. According to the actual situation, the combination of the above methods will have a better effect.

Use baking soda.

Wash the fruit, add a small amount of salt, soak in water for 10 minutes, and wash it again.

Wash with baking soda, add 5 10 grams of edible alkali to 500 ml of water to make alkaline water, soak the preliminarily rinsed fruit in alkaline water for 5 15 minutes, and repeat washing 3 times with water.

There are residual carbamate insecticides that will accelerate the decomposition with the increase of temperature, so some fruits that are difficult to treat by other methods can be removed by heating to remove part of the residual pesticides, such as putting the washed fruits in boiling water for 2 5 minutes and then removing them, and then washing them with water for 1 or 2 times before cooking and processing.

Soak it in light salt water and wash it with dish soap.

In the past, especially when food was scarce, food was extremely precious. In addition, in the past, the water resources were not as clean as they are now, and some elderly people generally picked and picked up the wild fruits on the trees, or after the food fell into the ground, they were wiped with their sleeves and then eaten.

If the younger generation sees this phenomenon, they will say why not to wash, and most of the old people will say "it is not clean, and there is no disease after eating".

If this sentence is put to the present, is there a problem, is there any scientific basis?

In one study, it was found that if parents clean their children's environment too much, let their children live for a long time. However, if the child is placed in a dusty place, it is not conducive to the child's resistance to external harmful substances, and increases the probability of allergies, asthma, respiratory diseases, etc.

The same is true for adults, where the body's resistance is weakened in places that are too clean, and then in places full of bacteria and pathogens.

In the past, people's various conditions would be a little worse, even if they ate some bacteria, under the function of the body's strong immune system, it would not easily affect their health.

However, for the sake of people's health, we need to be cautious about food, and we must wash the skin of the fruit frequently before eating fresh fruits. It can avoid pesticide residues on the skin of fruits, avoid people with weak stomach, or people who have suffered from gastrointestinal diseases, reduce the probability of food poisoning, and reduce the probability of diarrhea, bloating, vomiting, and dizziness.

In addition, in related research, it has also been found that the nutritional value of some fruit peels is still relatively high, such as apple peels, as well as grapefruit peels and orange peels, although the latter two foods cannot be eaten directly, they can also be used to boil water and drink after we clean them.

Among them, there are volatile substances, dietary fiber, organic compounds, etc., which are also very beneficial to health, can provide rich nutrients to the body, and are beneficial to daily bowel movements and gastrointestinal health.

In cleaning, you can use a small amount of flour, such as cauliflower, broccoli, ordinary, which are more troublesome in cleaning, and put some flour in the water to effectively clean.

Of course, for those who don't like to eat fruit skins, even if the fruit skins are slightly more nutritious, there is no need to eat fruit skins because of this nutrition. So, you can follow your usual habits according to your hobbies.

In addition, if the fruit or the food we eat in our daily life has mildew, rot and other deterioration, this kind of reluctance is not reluctant.

This kind of food not only has food safety problems in the nutrients, but also produces mycin that can threaten people's health.

Mainly a lot of you can't go to pesticides Strawberries, blueberries, tomatoes, what do you say In the process of growing You said that kiwifruit has been boosted With the process of its growth There is no way to avoid this And peeling at the same time a lot of nutrients are also lost Now there are too many reports on health Don't be too superstitious Try to wash it The best pesticide damage is simply endless But those vegetable potions are too much Pay attention when buying Fruits are originally detoxification Don't worry too much about pesticides.

After the fruit is peeled, there are no pesticide residues.

It's okay, the residue is very small, there is no harm, don't worry.

Usually, as long as the pesticide is concentrated on the peel, it will be better if it is peeled.

How to clean pesticide residues on fruits and vegetables?

1) Wash with water and soak: especially leafy vegetables, be sure to wash and soak first, otherwise it is equivalent to soaking fruits and vegetables in diluted pesticide water. It is necessary to wait until all the cleaning is done before cutting the vegetables, otherwise the pesticide residue will seep into the vegetables along the cut surface.

2) Wash first and then soak in alkaline water: first rinse the surface dirt thoroughly, soak it in alkaline water for 5-15 minutes, and then wash it with water 3-5 times.

3) Peeling method: Vegetables and fruits with uneven appearance or fine hairs are more likely to be contaminated with pesticides, so those who can be peeled before eating must be peeled.

4) Heating method: Carbamate insecticides will decompose faster with the increase of temperature. Such as green peppers, cauliflower, beans, celery, etc., it is best to fry or burn them in the pan.

Blanch it with boiling water.

5) Sunlight: Vegetables dried by sunlight have less pesticide residues.

6) Storage method: For vegetables that are convenient for storage, it is best to put them for a period of time, the oxygen in the air and the color enzyme in the vegetables have a certain decomposition effect on the residual pesticides.

During the cultivation of du fruit, for.

In order to prevent insect pests, in fact, many pesticides are hit on the roots, and there are directly injected into the skin of the plant, this method of killing insects from the inside, resulting in pesticide pollution and pesticide residues, can not be eliminated by simply peeling off the skin of the fruit. The most nutritious part of many fruits is the skin, and peeling off the peel is a waste of nutrients.

A general principle approach to removing pesticide residues from fruits and vegetables.

1. Clean the residual pesticides

The best way to do this is to rinse with plenty of tap water, soak in 1% salt water for 10 minutes, and then rinse off with clean water.

2. Wash without detergent:

The skin of vegetables and fruits is thin and wrinkled, and it is easy to seep into the vegetables and fruits from the fracture surface if you use detergents, and the detergents usually contain fluorescent agents with bleaching effect, which are carcinogenic risks, and even when using detergents labeled "for vegetables", they also contain more or less harmful substances to the human body.

3. Use a soft-bristled brush to wash

Cucumbers, green peppers, bitter gourds and other melons and fruits that can be boiled without peeling have uneven surfaces and pesticide residues that are not easy to wash, so they need to be cleaned with a soft brush.
