Why does peeling yam cause itchy hands? Teach you 4 ways to peel easily without itching
The ingredient "yam" must be familiar to everyone. It is a type of food that has the same origin as medicine and food. According to research reports on health science, yam contains a lot of substances that are beneficial to the human body, including protein, carbohydrates, vitamins, starch ethers and so on.
Proper consumption of yam can have many effects such as invigorating the spleen and stomach, moistening the lungs and relieving cough, lowering blood sugar and blood lipids. The shadow of yam can be seen in many proprietary Chinese medicines and health products for the treatment of gastrointestinal diseases.
Moreover, the taste of yam is quite good. After steaming, it is soft and sweet, which is very popular among friends of all ages. However, in the process of making yam, there are many difficulties.
There are many people who don’t know enough about yam. They start peeling the yam without treatment when they buy it. After a while, the hands start to itch. People mistakenly think that this is because they are allergic to yam, and they give up eating yam directly.
But in fact, most people will experience similar symptoms when they come into contact with yam without any measures . The reason for this is not because I am allergic to yam, but because yam contains a special substance called "saponin".
In the process of removing yam skin, a mucus is produced, and the protein contained in it, diosgenin, can irritate the skin and cause side effects, which are redness, tingling and itching of the skin.
Because everyone's susceptibility to the substance is different, the duration of symptoms varies . Some people react very quickly, and in the process of peeling, the symptoms of hand itching appear. For some people, symptoms may appear after a period of time.
So the question is, what can I do to avoid itching?
1. Wear gloves
This is the most direct and effective way. If you have experienced itchy hands, or you are dealing with yam for the first time, you can put on disposable gloves in advance, or wrap the wound with plastic wrap, so as to avoid hand There is direct contact between the skin and the yam, but it should be noted that when removing the gloves, it is best to rinse with water to prevent the mucus from touching the hands;
2. Bake with fire
A large number of research investigations have shown that the saponin in yam is not resistant to high temperature. If you are afraid of allergic reactions when peeling, you can wash your hands with water after peeling or cutting , and then bake it on the fire to make the saponin completely disappear. However, this method has certain risks, and you should avoid being scalded by flames during operation;
3. Steamed directly with the skin
If you don't want to eat crispy yam, such as making blueberry yam puree, you don't need to peel it in advance. You can steam the yam with the skin, and then peel it to make it delicious. In this way, in the process of high-temperature steaming, the saponin has been destroyed and will not cause itching.
****## 4. Vinegar cleaning
After peeling, the symptoms of itchy hands appear, you can pour a small amount of vinegar in the washbasin, and then soak your hands in it, the itching will be relieved in about 5 minutes.
The reason why it is effective is that the substances in vinegar can destroy the saponin on the yam skin, but compared with baking with fire , the effect of this method is slower;
Finally, I would like to remind everyone that if you have itchy hands when cutting yam, you can try the above methods to relieve it.
It should be emphasized that after the symptoms of hand itching appear, do not scratch directly with your hands, which will not only scratch the skin, but also cause symptoms such as redness, swelling, and tingling. If the symptoms of hand itching persist and are not relieved by the above methods, it is also necessary to seek medical advice in time.****
