The inside of the potato is black

The normal color of potatoes should be yellow or some green and white, but potatoes with black circles or black hair are spoiled potatoes. Regardless of whether they are not mature or have already spoiled, they may cause poisoning such as diarrhea, burning sensation, dizziness, headache or vomiting after use. These black potatoes cannot be eaten because they contain some bad elements.

Is it poisonous if the inside of a potato turns black?

The inside of potatoes turns black and produces toxins.

Generally, fresh potatoes contain a toxic substance called solanine, but the amount is very small and will not cause poisoning. However, unripe potatoes and potatoes with black circles or spots contain several times more solanine, and eating them can cause poisoning symptoms such as diarrhea, burning sensation, dizziness, and vomiting.

Can I eat potatoes with black circles inside?

Potatoes with black circles inside cannot be eaten.

Generally, black circles, black spots, and black spots will appear inside potatoes after they are stored for a long time. This is actually potato ring rot. The potatoes looked normal on the outside, but were rotten on the inside. This type of potato is very watery, hard, and has a strange smell, so it is recommended that you discard it.

Can sprouted potatoes be eaten?

Sprouted potatoes cannot be eaten either.

If fresh potatoes have sprouts, do not eat them. Because the solanine toxin content in it has increased exponentially, symptoms of poisoning will appear after consumption, and in severe cases, the respiratory center may be paralyzed and death may occur.

Precautions for eating potatoes

1. When eating potatoes, it is best to remove the skin because most of the solanine substances are in the potato skin.

2. Potatoes have a mild laxative effect. People with weak spleen and stomach should eat less to avoid symptoms of diarrhea and abdominal pain.

3. Pregnant women should eat less potatoes. If pregnant women eat potatoes for a long time, the solanine component will affect the development of the fetus.

4. Potatoes should not be exposed to the sun or frozen, and should be stored in a cool place.

How to choose good potatoes

1. The surface must be smooth, without scars or pits. The outer skin is a good protective layer for potatoes.

2. The potatoes should be uniform in size. Do not choose small potatoes as they have poorer quality.

3. The brighter the color, the better. Dark yellow means the potatoes have been left for a while.

4. Try to choose dry potatoes. Potatoes that have been soaked in water will spoil easily if stored for too short a time.

5. Do not choose immature green potatoes or potatoes with spores because they are toxic.
