Why do potatoes turn dark and spoil after peeling?
After you peel the potatoes, after a few hours they will begin to turn black. The reason for this is the substance it contains called tyrosine. Initially, it has a transparent color, but when it interacts with air, oxidation occurs, which is why the color of the vegetable changes.
Store-bought potatoes darken more slowly because they are treated with various chemicals. A self-grown vegetable will begin to change color within 1.5-2 hours. Using this method, you can check potatoes for the presence of harmful substances in them. Boiled potatoes do not change color at all, since tyrosine is destroyed during heat treatment.
The color change does not affect the taste and quality of the potato, so even after the appearance of black color it can be consumed.

Tips from Mr. Summer Resident: features of defrosting and cooking frozen vegetables
You need to freeze and defrost according to the rules that our portal https://mrdachnik.com reminds you of:
- If the products have been subjected to heat treatment, then before freezing they must first be cooled at room temperature, then cooled in the refrigerator.
- Defrost in the reverse order: remove the dish from the freezer, place it on a tray and place it in the refrigerator for half a day. Slow thawing allows food to absorb moisture lost during freezing. This way the taste is preserved as much as possible. But, if you don’t have time, you can use the defrosting function in the microwave.
How to cook frozen potatoes depends on the type in which they were stored:
- whole or pieces of raw fruits, do not need to be defrosted when cooking, their cooking in the oven or in a frying pan increases by only 5-7 minutes. At the same time, there is no need to increase the cooking time for the soup, since such potatoes will defrost very quickly in a boiling broth;
- French fries must be taken out of the freezer and immediately plunged into hot oil;
- Fried potatoes and mashed potatoes can be placed in the microwave for a few minutes to reheat directly when eating.

You can keep them in the refrigerator, but not for long, because after a few days they will lose their taste, but you can freeze them correctly, even already prepared dishes.
