Pesticide residues are harmful, how to remove pesticide residues in vegetables?

Tips for cleaning pesticidesMany friends should not use detergent when cleaning vegetables, fruits and vegetables, which will lead to the residue of detergent, or it is inconvenient to wash by hand excessively, resulting in damage to the surface of the food, so that the nutrients also flow out.

Water soaking washing method

Rinse off the surface waste of vegetables with clean water first, and then soak them in clean water, but the soaking time is preferably not less than 10 minutes. In this way, cleaning and soaking twice can eliminate most of the residual pesticide components.

Storage

The oxygen in the air has the effect of dissolving a part of the pesticide, so for some vegetables and fruits that are easy to store, the method of increasing the storage time can be used to reduce the pesticide content of a part. For example, vegetables that are not easily perishable, such as squash and winter squash, can be left for more than 3 days before eating.

Add the auxiliary soaking washing method

It can be soaked and cleaned with alkali (small soda), vegetable and fruit detergent, and rice washing water (preferably with the first 2 times). Soaking vegetables in that water for 5 to 15 minutes can remove methyl parathion insecticides contained in the surface of vegetables and fruits. After soaking, be sure to rinse thoroughly and tidy.

Heating method

Some pesticides dissolve faster as the temperature rises, so they can also help remove pesticide residues. For example, chili peppers, long beans, lettuce, green beans, etc., can be washed with water first, then poured into boiling water and soaked for 2 to 4 minutes, and then rinsed with water 1 to 2 times.

Peeling method

This is also the most effective way, but only for these vegetables with the skin. For example, loofahs, carrots, winter melons, apples, etc., it is enough to immediately peel off the skin with residual pesticides with a peeler.

Reminder: Since most of the pesticide residues are on the surface of vegetables, fruits and vegetables, cutting off the skin is very effective for removing pesticide residues, although it will damage some nutrients. Rinsing must be carried out before and after peeling, so that it is not easy to transfer pesticide residues to the fruit.

The above methods have a good effect on removing pesticide residues in vegetables and fruits, and they are also convenient and feasible. In order to better our own physical and mental health, we must pay attention to rational use.

Peeling method

Although the solubility of methyl parathion, organic mercury and pyrethroid pesticides in water is very low, they are soluble in organic solutions or fruit wax liquid, and there are many fruit waxes on the surface of vegetables, which are very easy to digest and absorb pesticides. Therefore, vegetables that can be peeled, such as loofah, cucumber, winter melon, etc., should be peeled before eating.

Rinsing with running water and soaking method

Generally, after buying vegetables, they should be rinsed with water 3 or 4 times, and then soaked into clean water for 1-2 hours before rinsing. Water flushing is the main way to remove waste and residual pesticides from vegetables, fruits and vegetables, especially for leafy vegetables such as Yongcai (kale), broccoli, vegetables, oilseed lettuce, green cabbage, etc. For cabbage vegetables, you can first remove 1-2 leaves from the surface, then cut and rinse with water 2 3 times, and then soak in clean water for 1 2 hours before cleaning to eliminate residual pesticides.

The order of water rinsing and soaking washing should not be reversed, otherwise the pesticides remaining on the surface of the leaves will penetrate into the vegetable tissue cells during the whole soaking process).

When cleaning vegetables, you can add some vinegar or salt, and then soak in water for about 20 minutes, which can remove some pesticides left in vegetables, and you can also buy some detergents for cleaning melons and fruits online, which can also remove some pesticides on vegetables.

First of all, the vegetables should be placed in water, add an appropriate amount of baking soda and table salt and soak for 20 minutes, then scrub them with your hands and wash them again with water.

At this time, you can use a fruit and vegetable cleaner to wash it carefully, then you also need to rinse it completely with running water, and finally you can also blanch it with water before eating.

These will be dissolved by the moisture in the soil as fertilizer, and the plants will turn it into essential elements for absorption, so it is recommended not to worry, it will not cause human poisoning.

1. Use water to rinse and soak most pesticides are acidic, as long as you use slightly alkaline rice washing water or detergent, you can remove most of the pesticides, but do not break the vegetable leaves in the washing process, otherwise it will lead to secondary pollution in the vegetable leaves. Most pesticides are water-soluble, generally on the surface of vegetables, as long as they are cleaned well, the surface of the pesticide can be cleaned.

2. When eating vegetables, you can peel off the skin, many vegetables have the most pesticides attached to the outermost leaves, and the skin can be peeled off to avoid the risk of eating pesticides. You can use hot water to scald, blanch the vegetables in hot water for about two minutes, and then rinse them twice with clean water to remove 90% of the residual medicine.

3. You can add salt and clean it, such as cucumbers or tomatoes and other vegetables after cleaning if I still don't feel at ease, you can put salt on the cutting board, gently turn the cucumber or tomato on the salt with your hands, and then wash off the salt with water, so that the pesticide on the cucumber can be washed off.
