How to tell which potato you can’t eat [food]
If the potatoes stored in the warehouse sprout or turn green, they should be discarded immediately. I think it’s okay to eat only after removing the damaged part, but it’s better to throw it away because it’s likely that it’s already damaged to the surroundings. If you eat incorrectly, you may have symptoms such as abdominal pain as well as vomiting and dizziness.
The sprouted potatoes contain a toxic substance called ‘solanine’. Solanine is the main ingredient of a toxic compound called “glycoalkaloid” in potatoes, and is a kind of natural insecticide produced by eggplant crops such as potatoes. It occurs when potatoes turn green, especially in sprouts. In this case, 100g is known to contain about 7mg of solanine. Eating more than 20mg of solanine can cause symptoms such as abdominal pain, vomiting, dizziness, and shortness of breath. If you don’t eat a lot of potatoes, you can only develop minor symptoms, but on the contrary, people who are sensitive to allergies can suffer from food poisoning even if they eat a little.
Solanine is also high in potato peelings. If the skin turns green, it means that the solanine content has increased, and even in this case, it is better to throw it away immediately. Solarin is resistant to heat, so it does not disappear easily even if you cut off the discolored area or buds and cook them in hot water.
It is better to store potatoes in a place that does not light well. Exposure to sunlight can produce more solanine. It can be stored at room temperature for up to two to three months, but if it is stored in the refrigerator, the storage period is reduced. Store them separately because they can get soft quickly if left next to moist foods like onions. In addition, if you want to store potatoes for a long time, it is recommended to put them in black bags, newspapers, or boxes in a well-ventilated place. The temperature of the storage area is suitable from 7 to 10 degrees. If it is stored at room temperature above 10 degrees Celsius, do not exceed 1 week. If you have peeled potatoes, soak them in cold water, drain them, wrap them in plastic bags, wrap them in plastic bags, and store them in a refrigerator. Potatoes can be easily damaged because they are vulnerable to air exposure when cut and stored.
