Is cucumber astringent because there are pesticide residues on the surface?

With the arrival of summer, the cucumbers are ripe. In the summer, make a cold cucumber salad, accompanied by beer, it is a cozy! I don't know if you have found such a problem, if the cucumber is not peeled, there will be a faint astringency in the mouth.

What's going on here? Many people will say that "there is pesticide residue on the surface". In fact, this is a rumor, in the countryside, some farmers grow cucumbers without spraying pesticides, but they will taste astringent.

So it's not pesticide residues, the real reason is this, let me tell me my opinion! <>

Cucumbers taste astringent because there are substances called picrin, propanol disic acid, etc., on the cucumber skin. Let's talk about bitters first, cucumbers themselves contain a small amount of bitters, and in the yellow tail, there are more of the substances, so the tail is also more bitter and bitter. And this kind of substance can improve the body's stomach and spleen, promote digestion, and increase appetite.

Let's talk about propanolic acid, this substance reacts with saliva in the mouth, and it makes people's mouths feel astringent! It is also good for the human body, we often say that eating cucumbers can **, in fact, it is because of this substance in cucumbers. <>

Cucumbers are very nutritious, and eating them in summer can cool off the heat, and obese people can eat more. Don't worry that the bitter taste inside cucumbers is due to pesticide residues, it's just a rumor. Cucumbers have a great effect, and some people use cucumbers to make **, facial cleanser.

Therefore, it can be seen that cucumber has a great effect on beauty and beauty! If you don't believe me, you can wash the cucumber and cook it at high heat, so that the pesticide that adheres to the surface can also be removed! <>

The above is the opinion, in fact, it is good to have this concern, after all, many vegetables are now sprayed by pesticides to improve yields. However, many experts have also explained that cucumbers will have an astringent taste, which is not a pesticide residue, but the original taste of this species. After reading this article, you can eat cucumbers with confidence!

So what do you think causes cucumbers to have a bitter taste? Let me know what you think!

Cucumbers taste astringent, not because of pesticide residues on the surface, but because cucumbers contain a substance called "bitters", which can make cucumbers astringent.

Not a pesticide residue. Cucumber tastes astringent because it contains more "propanolic acid" and "alkaloids", which can make our mouth feel astringent and numb.

No, because the surface of the cucumber itself contains propanolic acid, picrin, etc., so it will cause us to taste a little bitter, not pesticide residues!

Now there are generally cheap ones, and there should be no high ones. Cucumber is a temperature-loving and humidity-loving plant, with a suitable growth temperature of 18 32, a suitable air relative humidity of 70% 90%, and a soil moisture of 85% 95%.

Cucumber has a shallow root system, so it should be cultivated in humus loam soil rich in organic matter and good air permeability. The soil should be mildly acidic to weakly alkaline. It can be applied with rooting agent and Yanwo biological fungus.

Seedling fertilization: use Yanwo water-soluble fertilizer, fully and evenly. If you find that there is a lack of fertilizer at the seedling stage, you can use Yanwo potassium dihydrogen phosphate foliar fertilizer and spray it on the foliage.

It is conducive to cultivating strong seedlings.

Plantar fertilizer: Generally, the roots enjoy rooting agents and Yanwo biological fungi agents, which are conducive to slowing down seedlings. Soil top dressing:

The yield of cucumbers per mu is 5000 kg, and a total of 8 10 times of topdressing is required from planting to the end of harvesting. The first top dressing after planting slow seedlings was mainly water-soluble fertilizer. In the peak period of vegetable melon, increase the number of top dressing.

It is conducive to promoting the normal development of fruits and the healthy growth of plants.

We all know that cucumbers have many uses, cucumbers cut into cucumber slices and applied to the face have the function of beauty and beauty. In the summer heat, drinking some cucumber juice or cucumber soup can also have the effect of cooling off the heat. But many friends react that they will feel a little bitter in their mouths after eating cucumbers, what is the reason for this?

The reason why eating cucumbers has a bitter feeling is actually because there is a special substance on the surface of cucumbers, which is tannins. And this substance is found in many vegetables and fruits, such as persimmons, tomatoes and other substances with a white layer on the surface, and these substances are tannins.

Are the straight cucumbers and the curved cucumbers because of pesticides? Actually, no, the shape of cucumber growth is actually related to the environment and variety in which it grows, not because of pesticides. Some cucumbers are grown in fertile and sunny places, which is sweet and delicious, while some cucumbers are not grown in sufficient conditions and cause their shape to change.

Some people think that the cucumber with flowers is due to hormones, but in fact, it is because the farmer applies anti-falling pigment to the body of the flower, which makes it difficult for the flower to fall off. However, this type of hormone is used within a safe range and will not cause harm to the human body, so you don't have to worry.

Now you know why you feel astringent when you eat cucumbers.

Definitely to play pesticides, do not play pesticides to harvest one, the second cucumber seedlings on the leaves yellow, long spots on the death, every other week to play pesticides, a few weeks in a row, can make cucumbers not sick, prolong the picking period, improve the yield, do not spray melon farmers you say choose to play or not!
