Do not finely chop the potatoes, this will cause a loss of useful organic substances.
To extend the shelf life in water, you need to add a little citric acid or a slice of lemon itself.

If possible, it is best to peel potatoes immediately before cooking them, since prolonged storage in water washes out the starch from them, which makes the vegetable hard.

If the potatoes disappear while in the water, this can be determined by the gas bubbles that appear on the surface of the water. The tubers themselves become soft, as if sluggish and slippery to the touch. This can happen if potatoes are stored in water for more than 3 days at a warm ambient temperature. By cutting off the top layer and rinsing the vegetable well under running water, you can really save it, but the taste of such potatoes will be spoiled.

Storing mashed potatoes

How long to store puree in the refrigerator depends on its type. When raw egg yolks have been added to it, this dish cannot be stored even at low temperatures. Since raw chicken eggs are excellent flora for the proliferation of various bacteria.
Mashed potatoes to which sour cream has been added cannot be kept at room temperature categorically. This dish will turn sour within the next 2 - 3 hours.

The shelf life of mashed potatoes in the refrigerator is 24 hours.

Mashed potatoes with butter and boiled milk can be stored the longest. It can be eaten within 2 - 3 days from the moment of preparation. But after 48 hours this dish loses its taste.
If the shelf life of boiled potatoes in the refrigerator exceeded 1 day, they should be used as part of dishes that undergo heat treatment (casseroles, dumplings, pies).

Potato dishes are most in demand in the daily diet of every person. But in order to make the most of this vegetable, it is advisable to know how to store peeled potatoes, as well as the rest of the already boiled product.

How to determine the suitability of peeled potatoes

A thick, cloudy film on the surface of the water in which the vegetable lies indicates that it has begun to sour; such potatoes cannot be eaten . Another sign that a vegetable is unsuitable for eating is its softness. If your finger leaves a dent on the tuber, it means the product has lost too many valuable substances and should be thrown away.

A characteristic sour or putrid smell also indicates that the peeled tuber has disappeared . Dark or burgundy spots indicate that the pulp has begun to oxidize; it is also better to get rid of such vegetables.

Attention! After storage, peeled potatoes suitable for eating should be firm, even milky in color (shades vary depending on the variety), without dark areas and an unpleasant odor.

Reasons for browning of peeled potatoes

A dark coating forms on peeled potatoes within 1 - 2 hours. This is due to the increased content of the enzymes tyrosine and tyrosinase in tubers. In the process of contact with oxygen, this colorless substance begins to oxidize, as it contains copper. As a result of this reaction, a new black-gray substance is formed.

After treatment with fertilizers containing nitrogen, peeled potatoes will spoil earlier than those grown on your own plot without the use of various chemicals.

A tuber that darkens after cleaning will not cause harm to health, but only loses its presentable appearance. Heat treatment leads to the destruction of tyrosinase. This is why boiled potatoes do not darken, just like raw ones.

How peeled potatoes are stored in enterprises

The reason for this is the amino acid tyrosine and the enzyme tyrosinase derived from it. When the top layer is removed, the tuber becomes vulnerable to oxygen. When these chemicals react, the potato begins to oxidize and turns dark.

If during growth the plant received a lot of nitrogen-containing substances, then its tuber will darken faster after removing the skin. If nitrogen was not supplied to the plant during cultivation, the tuber will darken within 60 minutes.

Did you know? The world's most expensive potato variety

-
La Bonnotte. It is grown on the French island of Noirmoutier and sells for about 500 euros per 1 kg. Depending on what dishes the product will be used for, storage in the refrigerator is carried out in different ways:

Place the peeled tubers in a container with cold water and then put it in the refrigerator - this method is the simplest, and the fruits can later be used to prepare any dishes.
Blanching tubers - whole vegetables are immersed in a pan of boiling water for a few seconds, and then put in a bag and placed in the refrigerator. Hot water destroys the enzymes found in the top layer of the fruit, making them unable to react with oxygen. Blanched potatoes last longer than fresh ones, but have a specific taste and can only be used for boiling in their entirety.
Storing peeled potatoes in a tightly tied bag, from which the air has previously been released . With this method, the fruits can be used to prepare any dishes.
Grate the tubers and add finely chopped onion or garlic to the mixture. A container with such a semi-finished product can be kept in the refrigerator under cling film and used for preparing grated potato dishes.

In the freezer

The most reliable method for keeping peeled tubers fresh and tasty for a long time is freezing the fruit. It is best to freeze potatoes whole. But if you need to use chopped tubers for preparing dishes, then they are cut in advance into pieces of the required size and only then sent to the freezer.

In order to freeze whole peeled potatoes, you need to follow these steps:

Rinse the fruits and dry them a little with a napkin.
Place the tubers in a plastic bag, dividing them into portions.
Release excess air from the bag and seal it tightly.
Place packaged portions in the freezer.

In this way, you can store potatoes that you plan to use whole for cooking in the future—the frozen fruits just need to be immersed in boiling water and boiled until tender.

Important! If tubers are stored in the freezer for a long time, they can completely lose their taste.
Freezing potatoes cut into pieces is carried out in this way:

Rinse the tubers under running water, blot their surface with a napkin to remove excess moisture.
Cut the fruits into pieces of the required size.
Divide the chopped vegetables into individual portions and wrap each of them in several layers of cling film.
Place the tubers in the freezer.

When using this storage method, you need to take into account that in the freezer the starch in potatoes turns into sugar, so the defrosted vegetable will have a sweetish taste.

Terms and storage time

When peeled tubers come into contact with air, they quickly become covered with a dark coating. This occurs as a result of contact of iron, magnesium and potassium contained in the fruits with oxygen. A chemical oxidation reaction begins, the vegetable quickly turns black and spoils.

To extend the shelf life of peeled vegetables for consumption, various methods are used.

Let's consider how long peeled fruits can be stored at different temperatures:

at room temperature, the tubers can be kept in cold water for 3–4 hours, after which they lose most of the nutrients, and the taste of the fruit deteriorates;
blanched or fresh tubers packed in a bag can be stored in the refrigerator until the next day;
peeled fruits, soaked in water and refrigerated, can be stored for about 24 hours;
in the freezer at temperatures down to –18°C, the fruits can remain fresh for several days;
In a freezer at a temperature of at least –30 °C, peeled vegetables can last for several days or even weeks.

Important! When deep freezing, it is recommended to place the washed, peeled potatoes on a flat surface without wrapping them in a bag or film.
