Can Green Potatoes (Potatoes) Be Eaten After Turning Green, How to Handle Them, and What Not to Eat Them With

Potato, also known as Irish potato and taro, is an important food crop in our country. Because of its high nutritional value, low planting cost, easy cultivation, and good storability, it is widely planted. However, because it contains solanine, improper storage can lead to green skin, sprouting, and other phenomena, so when storing it, you must pay attention to the methods. So can green potatoes still be eaten? How should they be handled? What should they not be eaten with?

1. Can green potatoes still be eaten?

It is best not to eat potatoes after they turn green. This is because green potatoes mainly produce chlorophyll due to light exposure, which leads to an increase in solanine content, and solanine is sensitive to heat and acid and produces toxins. After accidental ingestion, symptoms of poisoning such as dry mouth and palpitations are likely to occur, and in severe cases it can cause death, so it is best not to eat them. However, if only a small area has turned green, simply cutting it off makes them edible.

2. How should green potatoes be handled?

1. Peeling: After potatoes turn green, simply cut off the green part thoroughly. This can reduce the solanine content, and eating them will not affect the human body.

2. Washing with water: After potatoes turn green, cutting them into shreds or chunks and soaking them in water can also reduce the solanine content. This is because solanine is soluble in water, and soaking and washing with water can effectively remove it.

3. High-temperature treatment: After potatoes turn green, cooking them at high temperature can reduce the solanine content. This is because solanine is sensitive to heat, and its content decreases after high-temperature treatment.

4. Acid treatment: After potatoes turn green, cutting them into shreds or chunks and adding a little vinegar to pickle them for a while can degrade the solanine. This is because solanine is sensitive to acid, and its content degrades after vinegar treatment.

3. How should potatoes be stored so they do not sprout or turn green?

When storing potatoes, try to place them in a dark, dry place with good ventilation, and generally they can be sealed in a cardboard box.

Key points for storing potatoes:

1. Do not put them in direct sunlight: Before storage, first remove potatoes with scars or rot, keep the surface dry, and then put them in a ventilated, dry, light-proof bag for storage.

2. Do not put them in a damp place: If the humidity is relatively high, potatoes will not only sprout but also rot, so when storing them, ensure both that the potato surface is dry and that the storage place is dry.

3. Do not put them in a high-temperature environment: At high temperatures, potatoes will sprout and rot, so when stacking them, try to put them in a dark place.

4. Do not put them together with other vegetables: Potatoes easily become moldy, especially when put together with other vegetables, so when storing them, try to store them separately.

5. Do not store them together with sweet potatoes: Potatoes easily sprout, especially when stored together with sweet potatoes, which can cause the sweet potatoes to become hard-cored and the potatoes to sprout, so it is best to store them separately.

4. What should potatoes not be eaten with?

1. Potatoes and persimmons should not be eaten together: When potatoes and persimmons are eaten at the same time, they produce indigestible sediment, leading to indigestion in the human body.

2. Potatoes and tomatoes should not be eaten together: After potatoes are absorbed by the human body, they produce hydrochloric acid, and when eaten with tomatoes they produce indigestible sediment, leading to indigestion in the human body.

3. Potatoes should not be eaten with bananas: When potatoes and bananas are eaten together, they produce toxins, causing poisoning in the human body.

4. Potatoes should not be eaten with pomegranates: When potatoes and pomegranates are eaten together, they produce toxins, causing poisoning in the human body.

5. How long can fresh potatoes be stored?

Generally, if fresh potatoes are stored properly, they will not turn green or sprout for more than half a year. However, as time goes by, the moisture will gradually dry out and the taste will become extremely poor, so it is best to buy only as much as you will eat. If you cannot finish eating them, you can make them into potato slices or braised food, which can effectively avoid waste.
