Can we eat sprouted potatoes?

The sprouted potatoes contain a toxic substance called solanine.

It is usually seen in Solanaceae, such as eggplant and uncooked tomatoes. Solanine is an alkaloid that is soluble in water.

In general, potato itself contains solanine, but its content is relatively low and does not cause poisoning. Potato peels 

turn green and potato epidermis germinate，Solanine content is relatively large! If you eat a lot of germinated potatoes, acute poisoning will occur!

Symptoms of poisoning are abdominal pain, nausea and vomiting, diarrhea, itching of the pharynx and mouth. If you take too much solanine, you may also die from respiratory paralysis, but the chances are usually not high.

Symptoms of poisoning are abdominal pain, nausea and vomiting, diarrhea, pharynx and oral itching. If you take too much solanine, you may also die of respiratory palsy, but it is unlikely to happen.

People often think that solanine can be cleaned with water, but it is not.Is it possible to remove solanine using high temperature heating? Unfortunately, the effect is not ideal. Since only 70% of the hot oil is fried for 10 minutes, 40% of the solanine can be removed, and some solanine can be decomposed by heating with vinegar.

Therefore, Vinegar potato silk is a relatively safe way to eat.

The green skin of potatoes also produces a solanine phenomenon, but we can remove the green part and eat the rest.

During potato sprouting, the starch in the potato is converted to sugar. If the potato is still hard after germination, it should be safe and we can remove the germinating parts and eat again. On the contrary, if the potato has shrivelled and softened, we cannot eat it!
