It is poisonous after long buds, so it can't be eaten generally, but those with a few buds can still be eaten after treatment. It stands to reason that potatoes can't be eaten after sprouting, but for potatoes that germinate a little, the sprouting part and around the bud eye should be dug deep, then soaked for more than half an hour, and the soaking water should be discarded, and then boiled thoroughly before eating. Because solanine is easy to decompose when it meets vinegar, some vinegar can be added properly when cooking to accelerate the destruction of solanine and become non-toxic.

Potatoes are potatoes, potatoes contain solanine, and the toxic component is solanine, also known as potato toxin, but its content is extremely low (0.005%-0.01%), which is not enough to cause poisoning. However, after the potato germinates, the solanine content in the bud and bud eye can be as high as 0.3%-0.5%. Normal people can cause acute sprouting potato poisoning by eating 0.2-0.4 grams of solanine at one time.

Extended data:

After potato poisoning, the incubation period is 10 minutes to several hours, and symptoms such as itchy tongue and throat, burning pain in stomach and gastroenteritis appear. Symptoms such as dilated pupils and tinnitus; Seriously ill people twitch, lose consciousness and even die. Potatoes should be stored in a dry and cool place or irradiated to prevent germination. Those who germinate more or whose flesh turns black and green can't eat it. If there is not much germination, the buds and their parts can be removed, peeled and soaked in water for 30 ~ 60 min, and some vinegar can be added during cooking to destroy the residual toxins.

In life, some people are reluctant to throw away potatoes, but they have food poisoning after eating them. At this time, if the symptoms of poisoning are mild, they can drink more warm water to speed up the metabolism of the body, so that the body toxins can be decomposed and metabolized out of the body without obvious harm to body form.
