Why is there more pesticide residues in cabbage? How do you remove pesticide residues from cabbage?

The reason for the high pesticide residue in cabbage may be related to its susceptibility to insects. There is a bug called "heartworm" that will burrow into the innermost layer of cabbage, and in order to kill insects, vegetable farmers have to use highly toxic pesticides to repeatedly "fill the heart", resulting in an increase in pesticide residues.

One word, more.

Many people think that if the cabbage has pesticide residues, it is okay to throw away the leaves of the outer skin, but in fact, there is no use for eggs. During the growth cycle of cabbage, at least two pesticides should be applied. The first should be beaten on the roots of the cabbage to avoid maggots eating the roots.

If you don't fight this pesticide, the ground maggot will bite off the root of the cabbage, and it won't grow.

The second pesticide needs to be applied to the cabbage leaves, which is to prevent normal insect infestation. Therefore, cabbage is also the most susceptible to pesticide residues. After experiments, it was found that the outer layer of cabbage was two pesticide residues, and the amount of pesticide residues in the inner layer was two.

The experimental results showed that the amount of pesticide residues in the inner layer of cabbage was not lower than that of the outer layer, and the pesticide residues in the inner layer were higher than those in the outer layer of cabbage.

Although the outer layer of cabbage wraps the inner layer, under the normal growth situation, the pesticide enters from the soil roots, and the pesticide residue "inside and outside" is the same, and it is not clean to wash the surface alone. When washing cabbage, be sure to break it one by one and wash it.

The same goes for Chinese cabbage.

Cabbage is one of the foods we all love to eat, but these parts are the most overlooked, and if not cleaned cleanly, it can cause food poisoning.

Oh. Cabbage, whose pesticide residue is second only to leeks, is also related to its very susceptibility to insects. There is a bug called "heartworm", which is a worm that burrows into the innermost layer of cabbage.

In order to kill insects, vegetable farmers have to use highly toxic pesticides to repeatedly "fill the heart", resulting in an increase in pesticide residues. Cabbage outer layer of leafy vegetables.

It is most likely to have pesticide residues, and try not to pick leafy vegetables with obvious pesticide spots on the surface. The spots are mostly blue-green.

or yellow, which is easily recognizable.

Correct Washing Steps:

Cleaning cabbage is carried out in three steps: First, remove the outer leaves. Cabbage.

The outermost layer of leafy vegetables is the most susceptible to pesticide residues, and it is best to pick off the outer layer of leafy vegetables before cleaning. The second is to remove the stem. The stems are also the most susceptible to pesticide residues, and the stems must be partially removed before cleaning.

The third is to wash with flowing water. It is best to soak in water for 30 to 40 minutes and then rinse twice with warm running water. Lightly brush each leafy vegetable.

After soaking and rinsing with running water, you can reuse the sponge noodles or a soft brush to lightly brush each leaf of cabbage to remove the residual pesticides. You can use rice washing water to wash vegetable leaves, and wash cabbage with rice washing water to effectively remove the silver of the poisonous shed limbs, because the rice washing water is alkaline, and the general pesticide is acidic, but it is necessary to confirm that the use of clean rice washing water.

Do not wash cabbage with salt water.

Do not use salt to clean cabbage, salt will form a brine film on the cabbage, just like a protective layer, during the cleaning process, clean water can not penetrate the protective layer, can not remove pesticide residues.

Is there a lot of pesticide residues in cabbage?

Cabbage is a vegetable that is prone to insect pests, and pesticides are indispensable. If you eat vegetables with pesticide residues, we all know the dangers. So someone said:

Cabbage grows from the inner heart to the outside, so the pesticide cannot be sprayed in the middle, as long as the outer layers of leaves are peeled off. Some people also say: cabbage is wrapped inward by leaves one by one, so the middle part of the pesticide residue is the most, and there are some insect eggs, impurities, bacteria and the like, so it must be cleaned one leaf at a time.

There are basically three kinds of harmful substances in the leaves of cabbage: one is pesticides, the other is bacteria such as E. coli, and the third is various pollutants brought by rain.

Regular vegetable pesticides will be degraded within 1 day to 7 days, and the cabbage core wrapping process is about 20 days. But given the current state of the market, it's better to wash it up.

E. coli is known to come from unrotted farm manure or human feces and urine, and can sometimes cause fatal diarrhea. Of course, bacteria are generally killed when cooking.

Anyone who has grown vegetables knows that cabbage is wrapped in a layer and a layer of medicine, otherwise it can't be wrapped, and the vegetable farmers themselves don't eat this dish. Once in a while, I peel off the layers and then soak them in flour and water, wash them, and rinse them vigorously with water.

Let me tell you: I never wash cabbage in restaurants, so I never eat cabbage made in restaurants.
