Why do potatoes turn green after a few days Can you still eat them

During the storage of potatoes, if they are exposed to light for a long time, the surface layer will produce chlorophyll, which will germinate, and then the chlorophyll part will produce a large amount of solanine. When potatoes turn green, it is obvious that there is more chlorophyll, and there is more solanine.

If you buy potatoes and you find them green, don't buy them. If you buy fresh potatoes at home and don't have time to eat them and turn green, at this time, the solanine content of potatoes is not high, just peel them, cook them at high temperatures, and add some vinegar, and most of the solanine will also be decomposed.

Potato sprouting produces a toxin called solanine, also known as solanine. The potatoes contain only 10 mg of solanine per 100 grams, while the solanine in green, sprouted, and rotten potatoes can increase by 50 times or more.

Children often cause convulsions and coma. If you eat 300 400 mg or more of solanine, the symptoms will be very severe, manifested as increased body temperature and repeated vomiting resulting in dehydration, as well as dilated pupils, photophobia, tinnitus, convulsions, dyspnea, blood pressure drop, and very few people can die due to respiratory paralysis.
