Good way to remove agricultural residues

What is pesticide residue? What are the dangers?

Pesticide residues refer to the general term that pesticides have not been decomposed after a certain period of time, but they remain in the trace pesticides, toxic metabolites, degradation, and impurities in crops, organisms, soil, and even atmosphere.

Pesticides mainly enter the human body through three ways: first, accidental contact, such as accidental food; second, long -term contact with a certain amount of pesticides, such as workers in pesticide factories, surrounding residents, and farmers using pesticides; third, daily contacts The residual pesticides in the environment and food and cosmetics are the main causes of pesticide pollution.

The harm of pesticides to the human body is mainly manifested in three forms: acute poisoning, chronic hazards, and "three triads" hazards (carcinogenic, teratogenic, and mutagenic). Long -term consumption does not clean the agricultural products with residual pesticides, which will inevitably bring a lot of harm to human health.

Which method is reliable to remove pesticide residues?

★ Soaking water washing method

It can remove part of the pollution pesticides. Generally, rinse the surface dirt with water, and then soak it with water for 20-30 minutes.

★ Alkaline water soaking and cleaning method

Prepare a bottle of baking soda in the kitchen, first rinse the surface dirt, soak it into the soda alkali water (usually 500-soda-10 grams of soda with 500ml water), and then rinse with water for 3-5 times.

★ Open water drift hot cleaning method

Some of the pesticides on some vegetables can make them fail through heating. Put the vegetables in boiling water and cook it for 1-2 minutes, and then clean it. The pesticides on the vegetables will also lose the effect. Such as spinach, bean horns, celery and other vegetables apply this method.

★ Tao rice water soaking and cleaning method

Before each family cooks rice, it usually wash rice with water several times. We can save rice water to wash vegetables.

★ salt water cleaning method

Washing vegetables with 1%-3%of fresh saline can not only remove some pesticides, but also remove various worms hidden in the root of the root of the vegetable root or the back of the vegetable leaves.

★ Clear water soda to fight flour removal method

For fruits such as grapes, cherries, cherry, and cherry, first rinse the surface dirt on the fruit, and add some flour in the soda-beaten alkaline water (generally 500ml of water to the soda) to increase the viscosity of the water. Soak for about 15 minutes, then rinse with water for 3-5 times. This method is very effective for removing residual pesticides, microorganisms, pollutants, impurities, etc.

★ Peeling method

Vegetables, fruits and fruits are relatively large, so peeling is a good, simple and practical method for removing residual pesticides.

★ Storage method

In the process of storage, active substances such as oxygen and enzymes in the air can react with residual pesticides to degrade pesticide oxidation, reduce the amount of pesticide residues and reduce its toxicity.

Notice! Do not use a cleaner!

The skin of vegetables and fruits is thin and wrinkled. If the cleaning agent is used, it is easy to penetrate into the fruits and fruits from the broken surface. The cleaner usually contains a fluorescent agent that is used by bleach. It contains less harmful substances to the human body.

When cleaning fruits and vegetables, please pay attention to these matters

Try not to destroy its structure before cleaning

In the process of cleaning, we must first clean it and fold it later, so that pesticides can be effectively avoided into the tissue when cleaning. For example, when you tear the cabbage, you should clean it first, and then tear the cabbage; the strawberry should be removed after cleaning; the bean horns should be cleaned first before picking it into small segments.

Cleaning and soaking time is not longer, the better

Studies have shown that the removal rate of various pesticides in 5-15 minutes is relatively balanced. If the soaking time is too long, pesticides may re -adsorb on fruits and vegetables.

Try to wash as much as possible in different types of fruits and vegetables

Most of the pesticides of fruits and vegetables are left on the surface. Pay attention to different categories when cleaning. If the lychee and strawberry are washed together, cross -pollution may be produced.

How can I pick up less fruits and vegetables with less pesticide residues

季 Try to buy fruits and vegetables that are rich in season. The fruits and vegetables that are not in the season need to spray a large amount of potions, which is more likely to cause pesticide residues;

的 Do not choose fruits and vegetables with different appearances. For example, the top of the tomato is tip, which is caused by the spray of vegetable farmers spraying, fertilizing, and ripening hormones. Such fruits and vegetables cannot be eaten;

“Don't deliberately choose" large and pervasive "fruits and vegetables. Really healthy and non -toxic leaves are thick, bright, shiny, densely rooted, and the beautifulness caused by pesticides is different;

Do not eat certain types of fruits and vegetables to avoid buying fruits and vegetables. To prevent vegetable farmers from spraying pesticides due to rush harvesting, fruits and fruits with a large amount of pesticide residues are: leek, spinach, cabbage, and spinach;

的 Edible fruits and vegetables with baggage. Such fruits and vegetables have fewer adhesion, such as grapes and stars. Vegetables and fruits that are not available with drugs or chemicals with chemicals;

留 Select the variety of fruits and vegetables with less pesticide residues. Such as garlic, onion, etc. with special smells, you need to peel the melon, radish, sweet potatoes, potato, etc.

的 Pesticide residues for continuous harvesting crops should be paid special attention.Continuous harvesting crops include peas, four seasons, cucumbers, etc. Due to the long harvesting period, in order to prevent some immature crops being pest, pesticides must be continuously sprayed, so there will be more pesticide residues.Finally, I will summarize it:

Fruit and vegetables with skin first choice to peel,

Vegetables with leaves can be simmered,

Other fruits and vegetables can choose the right method by themselves.
