When eating cabbage, is it necessary to clean the inner layer?

Judging by the growth process of Chinese cabbage. In the early stages, the outermost true leaves of Chinese cabbage.

Grow first. The leaf angles are very open and have a regular disc-shape. Then, in the leaf cup, begin to "fill the heart".

In other words, after the leaf cup is essentially wrapped, the heart leaf begins to grow and flesh out from the inside. According to this law of growth, many people believe that cabbage is the cleanest and does not come into contact with the outside world. In fact, if you look at dust and impurities, there is basically no cabbage.

However, from the point of view of pesticide residues, this is not the case.

<> fact, there are many bacteria that are invisible to the naked eye. During the growth process, insects patronize the aforementioned harmful pesticide components, as well as dust, various harmful substances and bacteria in the air. If left unwashed, they can unknowingly harm our body.

Therefore, it is necessary to remove them one by one, rinse them several times with clean water, and then wash the last cabbage.

This is because it starts growing from the inner layer. In other words, when the insecticide is applied, if the cabbage has not yet grown, and the insecticide is sprayed on the outer leaves, then the inside has not yet grown. When the inside grows, the insecticide does not easily enter because the cabbage is wrapped.

As for pesticides that are absorbed into the cabbage from the roots, <>

Because in cabbage tissues, washing is useless, and pesticide residues in tissues cannot be washed. The topping period of cabbage has entered the winter. At this point, the temperature drops and the insect cannot regenerate.

Therefore, there is no need to spray pesticides at all, so there is no problem with pesticide residues. Therefore, as long as the heart of the cabbage is clean and not exposed, there is no need to wash it.

Some people say that in fact, in the growth process of Chinese cabbage, at least two pesticides must be used. One is used for the roots of Chinese cabbage to avoid agricultural damage in the soil. If it is not applied, the roots of eating Chinese cabbage cannot keep the roots.

In addition, an insecticide should be applied to the leaves to prevent agricultural damage. There is no way to investigate whether it is true or not. After all, cabbage is not expensive now.

If too many pesticides are used, the cost will go up, and vegetable farmers will not want to.

Under normal circumstances, most people will only wash a few cabbage leaves outside, but most people don't. But some people feel that they have to wash it anyway, otherwise they will not feel comfortable eating. When the cabbage is ripe, the leaves close to the outer layer will slowly roll up and surround the middle leaves.

The middle part is originally wrapped directly, some need to absorb the sunlight and stretch, and the last part of the leaf will be rolled up.

Therefore, it can be said that only the external part is in direct contact with the outside world. If they are grown by their own home and do not use pesticides, they can only wash the outside of the pesticides. For most, you'd better wash them because you're not sure if they have pesticides or not.

In fact, it is still necessary to clean the inner layer, because there is a high probability that there will be pesticide residues in the inner layer.

When eating cabbage, I think it is necessary to clean the inner layer, because sometimes there is a lot of mud in the memory, and if you don't clean it, it will affect the taste very much.

The inner layer still needs to be cleaned, and some cabbage has pesticide residues, and if you don't clean it, you will eat the pesticides remaining on the cabbage.

Be sure to clean the cabbage heart before eating, and don't eat it without washing. Many people think that peeling off layer after layer of cabbage hearts is very clean and does not need to be washed. In fact, it takes 2-3 months for Chinese cabbage to grow to the core, during which it needs to be fertilized and treated many times, coupled with air pollution, bacteria have long existed in it.

If you want to wash, sometimes there will be insects or mud in it, so it is more hygienic to wash it.
