Solanum nigrum will be produced when potatoes germinate. This kind of nightshade is very harmful to our health. Therefore, if you don't want to throw away the sprouted potatoes, the blue part must be cut off, because the most abundant place of Solanum nigrum is in winter and spring, and potatoes are the easiest to bear seeds. When buying potatoes again, buy as little as possible. Can the germinated potato be eaten when it is cooked?

When potatoes germinate, they produce a toxin called solanine. Good quality potatoes only contain 100 mg of solanine per 100 g, while solanine in green, germinated and rotten potatoes can be increased by more than 50 times. Eating a very small amount of Solanum nigrum is not necessarily harmful to human body, 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 to 3 hours to get sick. The earliest symptoms are itchy mouth and throat, epigastric pain, nausea, vomiting, diarrhea and other symptoms.

Those with mild symptoms will heal themselves after 1 ~ 2 hours through their own detoxification function. If you eat more than 300 ~ 400 mg of Solanum nigrum, the symptoms will be very serious, such as body temperature rising and dehydration, repeated vomiting, pupil dilation, photophobia, tinnitus, convulsions, dyspnea and blood pressure drop. 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.

The slightly germinated and bluish parts and rotten parts on potatoes should be thoroughly removed. If the blue area of potatoes is large and there are many sprouted parts, they should be thrown 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 by using the acidity of vinegar can play a detoxification role.

Boiled potatoes should be crispy 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. If pregnant women eat too much Solanum nigrum, it may cause fetal malformation. There are many potatoes in my country, so it's nothing to eat.
