If the potatoes have grown a lot of buds or have turned green over a large area, it is not recommended to eat them. The solanine content is too high and is harmful to the human body.
If the potatoes are moldy or rotten, they cannot be eaten even if they have not sprouted or turned green. Aflatoxin, a toxin that is a carcinogen, is also produced.
Since solanine is an alkaloid, it is recommended to add vinegar for cooking when eating sprouted potatoes. When encountering acetic acid, a neutralization reaction will occur, destroying its toxicity.
✔How to preserve potatoes so that they don't sprout and turn green?
An old farmer who has been growing potatoes for decades said that there are several principles to keep in mind when preserving potatoes, namely, cool, dry, ventilated, and protected from light.
Now let me share with you some tips on how to preserve potatoes. Don't pile them directly on the ground. Using the method I mentioned, the potatoes will not sprout and turn green even if they are left for 6 months.
【Save potatoes】
1. Prepare a basin of water, add an appropriate amount of salt, stir and melt, add potatoes, and soak for 10 minutes.
2. Take out the potatoes and place them in a cool and ventilated place to dry. There should be no water on the surface.
3. Wrap the potatoes with plastic wrap. If you find it troublesome, you can seal it with a plastic bag. Finally, put it into a cardboard box, cover the box, and store it in a cool and ventilated place.
If there is heating or air conditioning at home, be sure to place it on the balcony where the temperature is lower, and do not place the carton directly on the ground, as it is easy to get damp and cause the potatoes to spoil.
When potatoes are soaked in light salt water, the salt will remain on the skin after drying, which can inhibit bacterial growth and prevent potatoes from sprouting. After wrapping in plastic wrap and packing in cartons, you can avoid light and maintain ventilation, and avoid moisture loss, so you can keep it fresh for a long time. Don't pile it directly on the ground in the future.
