How to eliminate the pesticide residues in vegetables and fruits to make the fruits and vegetables at home more healthy

how to remove the pesticide residues on vegetables and fruits?


can only remove part of the polluted pesticides, but washing is the basic method to remove other pollutants and pesticides from vegetables and fruits. Generally, the surface dirt is washed off with clean water, and then soaked in clean water for 20-30 minutes. The use of 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. Suitable for all kinds of leafy vegetables, such as spinach, day lily, leek, lettuce, coriander, cabbage, etc.

2. Keep a bottle of baking soda in your home kitchen. The main pesticides used in our country are organophosphorus pesticides, most of which will slowly decompose and even fail when they encounter alkali. Organophosphorus pesticides will decompose rapidly and fail in alkaline environment. Soaking in alkaline water is an effective measure to remove pesticide pollution. First, wash the surface dirt, soak it in baking soda alkali water (generally 500ml water, add 5g-10g baking soda) for about 15 minutes, and then rinse with clean water for 3-5 times. Suitable for fruits and vegetables: all kinds of vegetables and fruits.


the pesticide on some vegetables can be made ineffective by heating. Put the vegetables in boiling water for 1-3 minutes, and then clean them. The pesticide on the vegetables will also lose its effect. Such as spinach, lettuce, parsley, cabbage, celery, pepper, zucchini and other vegetables.

4. Rice washing water immersion cleaning method.

before cooking rice, every family usually washes the rice several times with clean water. We can save the rice washing water for washing vegetables, because the rice washing water is acidic, and the residual pesticides on vegetables will slowly decompose to failure after meeting the acidic rice washing water, so as to remove some residual pesticides on vegetables.

5. Salt water cleaning method.

using 1% – 3% light salt water to clean vegetables can not only remove some pesticides, but also remove various kinds of insects hidden in the root or the back of the leaves. Such as Chinese cabbage, cabbage, cabbage and other vegetables, before eating, you can break these vegetables into leaves by hand, and then soak them in salt water for a period of time. When soaking vegetables, it’s better to let every side of the vegetables fully contact with salt water. The pesticide residue on vegetables will lose its effect after soaking in water. Then, wash the vegetables several times with clean water until no colorful oil can be seen on the surface of the water.


for grapes, cherries, cherries and other fruits, first wash the surface dirt of the fruit, then add some flour in baking soda alkali water (generally add 5g-10g baking soda in 500ml water), improve the viscosity of the water, soak for about 15 minutes, and then rinse with clear water for 3-5 times, which is very effective for clearing residual pesticides, microorganisms, pollutants, impurities, etc.

7. Peeling.

the amount of pesticide on the surface of vegetables and fruits is relatively large, so peeling is a better, simple and practical method to remove pesticide residues. In this way, the residual pesticides and parasite eggs on the fruits will be completely removed. Suitable for fruits and vegetables: apple, pear, kiwi fruit, cucumber, Luffa, wax gourd, pumpkin, zucchini, eggplant, carrot, radish, potato, etc.

8. Storage method.

during the storage of vegetables, the oxygen in the air and the enzymes in vegetables can react with the residual pesticides to oxidize and degrade them, which can reduce the pesticide residues and reduce their toxicity. Therefore, the fruits and vegetables that are easy to preserve can be stored for a certain period of time to reduce the pesticide residues. Suitable for apple, kiwi, wax gourd and other non perishable species. During the novel coronavirus pneumonia outbreak at home, every household bought a lot of fruits and vegetables at once, and storage method played a supporting role in reducing pesticide residues.

9. The spectral effect of

will cause the decomposition and destruction of some pesticide residues in vegetables. The pesticide residues in vegetables exposed to sunlight were less. For vegetables which are convenient for storage, it is best to store them for a few days. The oxygen in the air and the chromozyme in vegetables have a certain decomposition effect on the residual pesticides. Suitable for Chinese cabbage, cabbage, cabbage, etc. During the novel coronavirus pneumonia outbreak at home, every household bought a lot of fruits and vegetables at once, and storage method played a supporting role in reducing pesticide residues.
