After the potato germinates, there will be a lot of toxic solanine around the bud hole, which is a neurotoxin that can inhibit the respiratory center. It is best not to eat sprouted potatoes. If you want to eat, you must dig deep into the cortex near the bud, then soak it in water for a while and cook it for a long time.

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.

Fresh potatoes contain a small amount of solanine, which is harmless to human body. However, during storage, the solanine content of potato increased gradually. When potatoes turn dark green or germinate, the content of solanine in buds and eyes is as high as 0.3-0.5%, and people can cause food poisoning by eating 0.2-0.4 grams of solanine. So after eating germinated potatoes, you may be poisoned by eating solanine.

Solanine can stimulate gastrointestinal tract, paralyze respiratory center and cause brain edema and congestion. In addition, it has hemolytic effect on red blood cells. Its symptoms are: first, itching and burning sensation in the throat, burning sensation or pain in the upper abdomen, mild vomiting and diarrhea, dizziness, headache and even dehydration, and severe cases can lead to heart failure and respiratory center paralysis and death.
