Potatoes, sprouts are dangerous? You can't eat it even if it changes like this

Along with potato sprouts, it is better not to eat the green skin because it has a lot of solanine, a toxic substance.

It is well known that potato sprouts have a toxin called solanine and should not be eaten. However, many people think that potatoes that have turned green can be eaten. Green potatoes also mean higher solanine levels, so you should not eat them.
Solanin is a natural insecticide created by eggplant crops such as potatoes and tomatoes to protect themselves. Consuming 1 mg per kilogram of weight on an adult basis causes symptoms of addiction such as headache, abdominal pain, and nausea. If you eat more than 400 milligrams, you may die. In general, 100 grams of potatoes contain about 7 milligrams of solanine. It can be ignored, but people who are sensitive to allergies can have difficulty breathing even if they eat more than 20mg.


Solanine is also high in potato peel. In particular, the green-colored shell means that the content of solanine has increased. Since solanine is not water-soluble, it is useless to boil it because it is not removed from water and decomposes at 285°C. Solanine is produced more when potatoes are exposed to sunlight. In fact, there are studies showing that potatoes placed on shelves outside the mart had four times higher solanine content than potatoes inside. Therefore, if the potato turns green, it is better to discard it and store it in a dark place.


Potatoes can be stored for up to two to three months at room temperature. When stored in a refrigerator, a carcinogen called acrylamide is generated due to low temperature damage and the storage period is reduced. Moist food like onions makes potatoes soften quickly, so it is better not to store them together. It's a good way to store one or two apples together. This is because ethylene gas from apples inhibits the germination of potatoes.
