How to solve pesticide residues in fruits and vegetables, and how to remove pesticide residues on fr

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.

Hello, we have a professional pesticide residue, paraffin antibiotics, is one of the research results of the national 863 program, but also the Olympic Games designated guarantee products, safety please rest assured,

Water immersion washing method: mainly used for leafy vegetables, such as spinach, lettuce, cabbage, etc. Under normal circumstances, rinse off the surface dirt with clean water first, and then soak it in water for no less than 10 minutes.

If necessary, fruit and vegetable cleaning agents can be added to increase the solubility of pesticides. Washing and soaking 2 or 3 times in this way can basically remove most of the residual pesticide components. Alkaline water immersion cleaning method:

Most organophosphorus pesticides can decompose quickly in an alkaline environment, so soaking in alkaline water is one of the effective ways to remove pesticide pollution from vegetables.

<> add 5 10 grams of edible alkali to 500 ml of water to prepare alkaline water, put the vegetables after preliminary cleaning into alkaline water, adjust enough alkaline water according to the number of vegetables, soak for 5 10 minutes, rinse with water, and repeatedly wash about 3 times, the effect is better. Cook on heat. Carbamate insecticides decompose more quickly as the temperature increases.

Therefore, some vegetables that are difficult to treat with other methods can be heated to remove some pesticide residues. Organophosphorus and carbamate pesticides are volatile and will have a multispectral effect after being exposed to sunlight, and the pesticides will be decomposed and destroyed. For fruits and vegetables such as apples, potatoes, and sweet potatoes, you can put them in the sun for 5 minutes to decompose the pesticides inside some fruits and vegetables.

Cook on heat. Most of the agricultural residues in fruits and vegetables are pesticides, which are easily decomposed by high temperatures. Therefore, for some fruits and vegetables that are difficult to treat by other methods, they can be washed with boiling water, and the effect of removing pesticide residues is very good.

Place the washed fruits and vegetables in boiling water for 1 to 2 minutes, then rinse with clean water. Suitable for beans, cauliflower, garlic, celery, etc.

It can be soaked, washed, disinfected, or soaked in hot water, so that it can have a disinfection effect and you can eat it with more confidence.

You can soak the vegetables and fruits you buy in clean water, wash them in alkaline water, or remove the skin from the vegetables and fruits when eating.

It should be washed with water, or soaked in water, or it can also be disinfected and sterilized, so that pesticide residues in vegetables can be removed.

Introduction: In the process of planting, vegetables and fruits need to be sprinkled with a lot of fertilizer in order to make them grow strongly. Therefore, people must wash fruits or vegetables after buying them in the supermarket or market, otherwise they will ingest too much fertilizer and breed a large number of bacteria and microorganisms, which will affect their health.

The topic I want to share today is how to eliminate pesticide residues in vegetables and fruits.

1. How to eliminate pesticide residues in vegetables and fruits?

You can buy vegetables and fruits, first rinse the dirt and soil on the surface with running water, and then soak them in water for half an hour. In this way, microorganisms, bacteria, and pesticides can be soaked out. After soaking, rinse it two or three times with running water to effectively remove it.

Vegetables and fruits can be cleaned by soaking in alkaline water, which can also effectively clean the dirt on the surface. After picking the vegetables, put them in boiling water and boil them for 1 3 minutes, and then wash them, then the residual pesticides on the surface of the vegetables will also lose their activity, this method is suitable for spinach, lettuce, purple cabbage, celery, peppers, zucchini, etc. It is also very good to keep the rice washing water in a basin and use the rice washing water to clean the residual pesticides in vegetables and fruits.

The residual pesticides on vegetables and fruits will slowly lose their activity after encountering rice washing water, and the residual pesticides can be effectively removed. You can add a small amount of salt to clean water, stir well, and turn it into salt water to clean vegetables and fruits, which is also very good, and will make people feel more at ease when eating.

2. Conclusion. You can prepare water, and then add some baking soda or flour to the water, stir evenly to wash vegetables and fruits, which is also a better way to clean the bacteria and microorganisms on the surface. However, after washing with baking soda and flour, you need to rinse it 3 to 5 times with running water to ensure contamination.

If you are not worried and are afraid of microorganisms and harmful substances remaining in vegetables and fruits, then you can peel them when eating vegetables and fruits. This method is suitable for apples, kiwis, cucumbers, loofahs, winter melons, pumpkins, gourds, carrots, turnips, etc.

Most of the pesticides used are organophosphorus, after encountering alkali, it will slowly decompose so that it loses its efficacy, first rinse the surface dirt, soak it in baking soda alkali water for about 15 minutes, and then rinse it with water 3 5 times.

You can choose to wash it with baking soda, or you can use table salt to clean it, and you should wash it several times at ordinary times, and you should soak it in warm water in advance, which can eliminate residual pesticides.

Vegetables and fruits can be cleaned with edible salt water, which can effectively reduce pesticides in vegetables and fruits.

1.Add a few drops of fruit and vegetable cleaner to clean water, and soak the fruits and vegetables in it, the surfactant in the fruits and vegetables can adsorb the residual pesticides and make the pesticides easy to remove (much better than using only water, salt water, etc.).

2.Then rinse with water, wash several times, and rinse the surfactant and the adsorbed residual pesticide together.

The surface of fruits and vegetables can be removed by rinsing with water for 3 to 5 minutes. There's no way to get rid of it. Now there is a kind of machine on the market to remove pesticide residues in fruits and vegetables, in fact, it is just an ozone generator, the principle is to use oxidation to remove pesticides on the surface of fruits and vegetables, and there is nothing that can be done about it.

Soak with dish soap for 2 hours and rinse with running water for 3 minutes.
