There is a brown circle inside the potato

Potatoes are a plant with strong ability to adapt to the environment, so potatoes are grown in most parts of China, especially in areas with severe cold climates, where potatoes have become the main food. When storing potatoes, you must pay attention to the correct storage method and avoid placing the potatoes in an overly humid environment, otherwise the potatoes will sprout. If you find a circle of brown stuff inside a potato, can you still eat it?

The brown or light purple spots on potatoes are caused by the pathogenic fungus Phytophthora infestans and Alternaria solanacearum, and of course they are not edible.

Potatoes are also called ground eggs, potatoes, sweet potatoes, etc.

Notes on eating potatoes:

Potatoes contain some toxic alkalis, mainly solanine and chaetomium, but generally speaking, the toxic substances will be decomposed after being cooked at a high temperature of 170°C.

Potatoes contain solanine, the toxic ingredient of which is solanine, also known as potato toxin. However, its content is extremely low (0.005% - 0.01%), which is not enough to cause poisoning. However, after potatoes sprout, the solanine content in their sprouts and eyes can be as high as 0.3% - 0.5%. If a normal human body ingests 0.2-0.4 grams of solanine at one time, it can cause acute sprouting potato poisoning.

Poisoning from sprouted potatoes occurs 2 to 4 hours after eating. Symptoms include: first a tingling or burning sensation in the throat, a burning sensation or pain in the upper abdomen, followed by nausea, vomiting, diarrhea and other gastroenteritis symptoms; those with more severe poisoning may suffer from dehydration, electrolyte imbalance and low blood pressure due to severe vomiting and diarrhea; in addition, they are often accompanied by dizziness, headache, mild impaired consciousness, etc. Severe cases may also experience coma and convulsions, and finally death from heart failure and paralysis of the respiratory center.

For potatoes that have sprouted a little, you should dig out the sprouted part and the area around the bud, then soak them for more than half an hour, discard the soaking water, and then add water to cook thoroughly before eating. Because solanine is easily decomposed by vinegar, you can add some vinegar during cooking to accelerate the destruction of solanine and make it non-toxic.
