Why can't germinated potatoes be eaten? Where is the toxin?

Why can't germinated potatoes be eaten? Where is the toxin? Potatoes are also called potatoes, yam eggs and potatoes. Due to improper storage, potatoes germinate easily in spring. People who eat sprouted potatoes often cause poisoning.

Why can't germinated potatoes be eaten?

It turns out that potatoes contain a toxin called solanine. In each100g potato, the content of solanine is only 8 8- 10/0g, while in germinated potatoes, especially those with purple-green pulp and rotten buds, eyes and skins, the content of solanine can reach about 500mg. People who eat 200 mg (about twice the content of solanine in germinated potatoes) may be poisoned. After eating a large number of germinated potatoes, there will be poisoning symptoms such as nausea, vomiting, diarrhea, itchy throat, dizziness, chest tightness and even coma, and finally death due to respiratory and circulatory failure caused by nerve paralysis.

Once the patient is found to be poisoned after eating potatoes, first aid should be given immediately:

1. Early gastric lavage, emesis and catharsis should be performed first. L-2% tannic acid solution or tea can be used for gastric lavage to precipitate solanine to reduce poisoning.

2. Patients with severe vomiting and diarrhea can be given atropine injection, and pay attention to supplementing water and drinking some sugar water and light salt water.

3. Symptomatic treatment: people with decreased blood pressure can be given antihypertensive drugs, stimulants can be used when respiratory and circulatory failure occurs, and artificial respiration and oxygen inhalation can be done.

Is the sprouted potato poisonous? Why can't germinated potatoes be eaten? The slightly germinated, blue and rotten parts of potatoes should be thoroughly removed. If the potato has a large blue area and many sprouted parts, you should throw it away. * Cut peeled potatoes into small pieces and soak them in cold water for more than half an hour to dissolve the remaining solanine in water. * Use the weak alkaline properties of Solanum nigrum to add it when cooking potatoes. ...

Why can't germinated potatoes be eaten? When potatoes germinate, they produce a toxin called solanine. High-quality potatoes only contain 100 mg of solanine per 100 g, while solanine in green, germinated and rotten potatoes can be increased by 50 times or more. Eating a very small amount of Solanum nigrum is not necessarily harmful to human health, but if you eat 200 mg of Solanum nigrum (about half a dozen potatoes that have turned green and sprouted) at a time, it will take 15 minutes to 3 hours to get sick. The earliest symptoms are itchy mouth and throat, epigastric pain, nausea, vomiting and diarrhea.

Those with mild symptoms will heal themselves through their own detoxification function after 1 ~ 2 hours. If you eat 300 ~ 400 mg or more of Solanum nigrum, the symptoms will be very serious, such as dehydration and repeated vomiting, pupil dilation, fear of light, tinnitus, convulsions, dyspnea and blood pressure drop due to rising body temperature. Few people will die of respiratory paralysis. Therefore, patients with severe symptoms should be sent to hospital for treatment as soon as possible.

Attention must be paid to prevent potato solanine poisoning.

* Don't eat immature green potatoes.

* Slight sprouting, blue parts and rotten parts on potatoes should be thoroughly removed. If the potato has a large blue area and many sprouted parts, you should throw it away.

* Cut peeled potatoes into small pieces and soak them in cold water for more than half an hour to dissolve the remaining solanine in water.

* Using the weak alkalinity of Solanum nigrum, adding proper amount of rice vinegar when cooking potatoes, and decomposing Solanum nigrum with the acidity of vinegar can play a detoxification role.

* Cooking potatoes should be crisp and thoroughly burned, and solanine can be partially decomposed by using high temperature for a long time.

If you feel a little numb in your mouth when eating potatoes, it means that potatoes still contain more solanine, so you should stop eating them immediately to prevent poisoning.

It has been reported that if pregnant women eat too much solanine, it may cause fetal malformation, so pregnant women should be especially careful.

The germinated potato itself has produced a toxic substance-solanine. Solanine is a natural toxin contained in potatoes. In the whole potato, the content of solanine is very small, generally, it contains 100 mg of solanine per 100 g. However, when potatoes are immature, germinate or turn green, solanine in potatoes will increase sharply, especially in buds, bud eyes and green places.

When potatoes germinate, they produce solanine, a neurotoxin. Potatoes do not cause poisoning under normal circumstances. However, when potatoes germinate or their skins turn green, poisoning often occurs after eating, especially in late spring and early summer. The reason of poisoning is that there is an alkaloid called Solanum nigrum in potatoes, which has a * * effect on gastric mucosa and can cause hemolysis, cerebral congestion and edema, paralysis of exercise and respiratory center and cause poisoning. Under normal circumstances, Solanum nigrum is rarely contained in potatoes. When germinated, the content of the skin and the surrounding meat increased greatly, which was 50 ~ 2000 times higher than that of the ungerminated potato. If you eat 25 to 50 grams of this potato, it will cause poisoning. Poisoning occurred 30 minutes to 3 hours after eating germinated potatoes. At first, the throat mucosa was itchy, the mouth was bitter and spicy, and there was a burning sensation in the stomach, followed by nausea, vomiting, abdominal pain, diarrhea and limb weakness. In severe cases, body temperature may rise, convulsions, cold sweat, dilated pupils, loss of consciousness, and finally death due to dyspnea. Mild patients recover after 1 ~ 2 days, while severe patients can be delayed to several days until death. The key to prevent sprouting potato poisoning is not to buy sprouting potatoes, but to store them in a dry and cool place. Toothed potatoes, such as few teeth, can be completely removed from the teeth and cut off the surrounding green meat, and then all the potato skins are cut off, cooked, boiled or fried with vinegar without poisoning; People with a lot of hair, teeth or green skin color should be abandoned.
