How to remove pesticide residues in leeks, and do leeks have pesticide residues

Hello, please refer to the following.

1. Baking soda. Take an appropriate amount of baking soda powder and mix it into water to wash the leeks and then rinse them with water, this method can clean the pesticide residues on the leeks.

2. Dish soap. Add a few drops of dish soap to the basin, add water and stir well, put the leeks in and gently wash them to wash off all stains and pesticides, and then rinse with water.

3. Take an appropriate amount of fruit and vegetable washing salt, add water to clean the leeks, and then rinse them with water, so that the residual pesticides on the leeks can be washed off.

4. Spread the bought leeks for a period of time, because the pesticides are volatile, so they will automatically volatilize after a period of time, and this method is also an effective way to remove the residual pesticides on the leeks.

5. Tap water. Wash the leeks repeatedly with tap water, or soak them in clean water for a while and then rinse them again with running tap water, which will wash away most of the pesticide residues on the leeks.

6. Flour. Flour has a lot of viscosity, and its stickiness can remove dirt and pesticide residues from the surface of leeks.

If leeks do not need to flower and bear fruit, but only need to grow leaves, nitrogen fertilizers such as urea, human urine, etc. If you need to apply some phosphorus and potassium fertilizers before flowering, it is recommended to use high phosphorus water-soluble fertilizers to promote leaf growth. Such as plant ash, rotted other fertilizers, etc.

Pesticide residues on leeks cannot be ignored, and it is simple and effective to do this with me.

Select leeks and remove the roots by half an inch. In general, the roots of leeks are where the most pesticide residues are located. When eating leeks, cut off the roots at least half an inch or more. After washing it with running water, soak it for 10 15 minutes, and then rinse it with water 1 or 2 times.

Leeks can also have pesticide residues. Therefore, after buying leeks, pay attention to cleaning. When buying leeks, don't choose the leaves are oily green, and thick and small, you should choose the leaves to smoke more and more yellow, and the small leeks are more normal.

When cleaning leeks, rinse off the surface dirt with water and soak them in water for at least 10 minutes.

Leeks are inevitably pesticide residues, so when eating, peel them first; Go wash it again.

That's reassuring.

But we have actually said many times that it is very normal to use some pesticides or agents in the cultivation of vegetables and fruits. As long as it is consumed reasonably within the specified range, and then carefully washed by us, there will not be much residue at all, and it will not cause harm to health.

As for saying that someone would soak leeks directly with copper sulfate, it is complete nonsense. If you do this, although it will indeed make the color of the leeks look more pleasant, it will also completely lose its freshness, and farmers will not be stupid to do such a thing.

In addition, many people love to eat leeks, all for the purpose of improving male function. Here, the dietitian of the ** nutrition class emphasizes that leeks do not have such effects at all. Leeks are a relatively nutritious vegetable, containing sulfur compounds, zinc, vitamin C and other substances, which have no connection with male function.

Finally, during the epidemic, many people have limited ingredients at home and eat "okay" every day. And if you're lucky enough to get your hands on leeks, why not make a delicious leek box for a delicious meal, and it's easy to operate

Add water to the flour first, the ratio is about 2:1, and let the noodles sit for about an hour. Then fry the eggs into cakes and break them, cut the leeks into small pieces after controlling the water, and stir thoroughly.

If you have conditions at home, you can put some vermicelli and other foods you want to eat, and then add salt, oil and monosodium glutamate and stir well.

Then it is time to test the skill, knead the good noodles into strips, then cut them into an even agent, and roll them into a thin dough with a thin side and a thick middle. Take the filling, spread it on the dough, fold it in half and seal the edges.

If you feel that you can't understand this operation, you can directly search for relevant teachings on the Internet, which is actually not difficult. After wrapping, it is natural to fry in the pan, and slowly fry it on low heat until golden brown on both sides.

First of all, some pesticide residues are volatile, so they need to be placed in a ventilated place for 1-2 days before eating after buying fresh leeks.

Secondly, soak for a period of time before eating, and add an appropriate amount of baking soda to the water when soaking. Because leeks generally use organophosphorus pesticides, one of the characteristics of organophosphorus pesticides is that they are inactivated when exposed to alkali. Or add appropriate edible salt, because the soaking of brine can cause leek cells to precipitate pesticide residues due to shrinkage and water loss.

Soak the leeks and pat them next to them, and then wash them with water before eating.

Third, cut off the leek root about a centimeter in length before eating it closed. Because pesticides must be applied to the roots of leeks to remove pests, the pesticide residues in the roots of leeks are the largest, so it is better to remove pesticide residues by cutting off part of the leek roots when eating.

There is skill in choosing leeks, and only when you master the skills will you pick delicious leeks.

When choosing leeks, be sure to choose a fuller color, you should choose a turquoise leek, and then when cleaning, you can soak it in water first, and then put some baking soda or salt. This removes pesticide residues and then rinses them several times with clean water.

Leeks themselves are not prone to insect pests in the process of planting, so they are rarely used, and pesticide residues are very low compared to other leafy vegetables.
