What is the best way to clean vegetables and fruits for pesticide residues?

The methods of cleaning pesticide residues in vegetables and fruits are: vinegar, flour, salt, and rice water.

Baking soda, fruit and vegetable detergent, dish soap.

According to the different types of fruits and vegetables, the appropriate method can be selected to remove pesticide residues on the surface of fruits and vegetables. When fruits and vegetables are exposed to sunlight for about 5 minutes, the residues of pesticides such as organochlorine and organic mercury can be reduced by about 60%.

1. Vinegar. Vinegar has many functions, not only can be used for flavoring, decontamination, sterilization, but also can effectively remove pesticide residues.

2. Flour. Generally, when cleaning apples, tomatoes and other fruits, flour can be used to remove pesticide residues, you can soak the fruit, sprinkle it with flour, and then scrub it, so that the pesticide residues on the fruit will be taken away by the flour.

3. 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 for a period of time, which can also have the effect of removing pesticide residues.

Fourth, rice water.

Fruits and vegetables can be soaked in rice water for 30 minutes, and then rinsed again, rice water is a more common method, but also to remove pesticide residues "good prescription", because rice water is weakly alkaline, can neutralize pesticide components, weaken the efficacy, rice water contains starch also has a very strong viscosity, so soaking and cleaning fruits and vegetables with rice water is simple and convenient, easy to implement.

5. Baking soda.

Whether it's fruits or vegetables, after washing, you can pour water into the basin and add baking soda.

Soak it for 30 minutes, then rinse it again with water once.

6. Fruit and vegetable cleaning agent.

Preparation, cleaning and soaking according to the instructions of fruit and vegetable cleaning agents can promote the dissolution of pesticides and remove most of the pesticide residues.

7. Heating. Generally, carbamate insecticides will decompose faster with the increase of temperature, this method is often used in spinach, celery, cabbage, you can first clean the surface dirt, and then put it in boiling water for 2-5 minutes to remove it, and then wash it with water 3-5 times.

The best way to clean pesticide residues in vegetables and fruits is to use a food purification machine, which adopts the water hydroxyl technology that has won the National Science and Technology Progress Award, without any chemical addition, only using tap water as the raw material for detoxification and purification, and cracking water molecules through innovative research and development of core components to generate a ·OH functional group (water hydroxyl and other functional groups) with strong oxidation ability, which can quickly kill bacteria, viruses and other pathogenic microorganisms on food, and efficiently degrade pesticides, hormones, Chemical residues such as antibiotics solve the two major food contaminants at one time, thus solving the global problem that food contaminants are difficult to remove.

The methods for removing pesticide residues in fruits and vegetables are:

One, peeling method:The amount of pesticides on the surface of fruits and vegetables is relatively large, so peeling is a better way to remove residual pesticides, which can be applied to pears, apples, kiwifruits, loofahs, melons, winter melons, green beans, basketballs, beans, carrots, etc., in the case of solving, it is not suitable for the fruits and vegetables that have been peeled in the future to carry out mixed storage to prevent environmental pollution again.

Second, water immersion method:Generally, vegetables, fruits, fruits and vegetables must be rinsed with water 3-6 times up and down, and then put into salt water to rinse 1 time, for the heart of vegetables and fruits, you can use a knife to cut first, and then put into clean water to soak for 1-2 hours, and finally rinse with water to eliminate residual pesticides.

3. Edible alkali immersion method:Methyl parathion insecticide can be quickly dissolved in acidic conditions, so this kind of method can reasonably remove pesticide residues, first of all, the waste on the surface of vegetables, fruits, fruits and vegetables can be washed neatly, and then soaked in edible alkali for about 5-15 minutes, generally 500ml of water can add 5-10 grams of edible alkali, and then scoop up and rinse with water 3-5 times.

Fourth, the rice washing water soaking method should be used to wash fruits and vegetables with rice washing waterAt this stage, the vast majority of China's dimethoate pesticides, methamidophos, phosphine, insecticidal double methyl parathion pesticides to carry out insect removal, because this pesticide will lose its toxicity when it encounters acidic substances, so it can be soaked in rice washing water for 10 minutes, and then scooped up and rinsed with clean water, which can reduce the residual pesticide components on the surface of fruits and vegetables. Methods for removing pesticide residues in fruits and vegetables.

Fifth, microbial elimination enzyme de-multiplication:When removing residual pesticides in vegetables, fruits, fruits and vegetables, you can put 1 individually packaged microbial elimination enzyme in clean water, and then soak vegetables, fruits, fruits and vegetables for 8-15 minutes.

Sixth, the storage method:Pesticides in the storage of natural environment will be due to the increase of time, slow dissolution of residual harmful substances, so for the storage time of melons, fruits and vegetables, it can be stored for a period of time, so that it can reduce the residual amount of pesticides, generally apples, kiwifruit, melon and other fruits and vegetables that are not easy to rot, suitable for storage time of more than 15 days.

7. Heat transfer medium:For carbamate insecticides, it will be quickly dissolved due to the rise in temperature, so for some fruits and vegetables that cannot be solved by other methods, a part of the pesticide can be removed according to the method of heating, and it can generally be applied to lettuce, broccoli, pepper, cauliflower, long beans, greens, cabbage, etc., you can first clean the surface waste of fruits and vegetables with water, and then put it in boiling water for 2-5 minutes, and then rinse it with water 1-2 times.

Soak in water and wash method. To remove part of the polluted pesticides, the surface dirt is generally rinsed off with clean water first, and then soaked in water for 20-30 minutes.

Alkaline water immersion cleaning method. Prepare a bottle of baking soda in the kitchen, rinse the surface dirt first, soak it in baking soda alkali water (generally add 5 grams to 500ml of water to baking soda 5 grams - 10 grams) for about 15 minutes, and then rinse with water 3-5 times.

Blanching cleaning method with boiling water. Pesticides on some vegetables can be inactivated by heating. Put the vegetables in boiling water and boil them for 1-2 minutes, and then wash them, and the pesticides on the vegetables will lose their effect.

Vegetables such as spinach, beans, celery, etc., are suitable for this method.

Washing rice water soaking cleaning method. Before cooking rice, every family usually washes the rice several times with clean water, and we can save the rice washing water and use it to wash the vegetables and prepare the skin.

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 part or the back of the leaf.

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 alkaline water (generally 500ml of water add 5 grams of baking soda - 10 grams) to improve the viscosity of the water, soak for about 15 minutes, and then rinse with water 3-5 times. This method is very effective in removing residual pesticides, microorganisms, contaminants, impurities, etc.

Peeling method. The amount of pesticides on the surface of vegetables, melons and fruits is relatively large, so peeling is a better, simple and practical method to remove residual pesticides.

Storage. 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.

The main thing to note is that the skin of vegetables and fruits is thin and wrinkled, and if you use detergents, it is easy to seep into the vegetables and fruits from the quiet fracture surface, and the detergents usually contain fluorescent agents that act as bleach, and even if you use detergents labeled "for vegetables", they also contain substances that are more or less harmful to the human body.
