If the situation is not serious, such as potatoes are fresh and not rotten, but only slightly sprouted, after peeling the skin to remove the sprouted parts, at the same time will be thoroughly dug around the eye of the sprout, remove the green, purple, green part, and then soak in water for half an hour, usually fully cooked can also continue to eat. However, if the potatoes have many sprouted parts and a large green area, it is recommended not to eat them for safety reasons. Because potatoes contain traces of nitrogenous steroid alkaloids, namely lobotropin, can stimulate the human intestinal mucosa, and has a paralyzing effect on the respiratory center. When potatoes are sprouted, the content of lobotropin increases, and its toxin effect is enhanced. If you eat potatoes containing too much lobotropin, you may experience symptoms of poisoning, such as numbness of the tongue, itching of the throat, nausea, vomiting, abdominal pain, diarrhea, etc. If you eat too much, it may also lead to death. Lobelia is a weak alkaline toxin. After washing and soaking potatoes with slight sprouting, adding an appropriate amount of vinegar during cooking can play a role in decomposing the toxin, in which case the potatoes can be eaten as long as they are cooked.
