People began to use eggs for food a very long time ago. This product was first appreciated by the people of India. There are eggs in this country began as early as 2.5 thousand years BC. Somewhat later, the Romans began to eat them, and then the inhabitants of other countries of Europe.
In Russian cuisine, eggs have long been used exclusively as a separate dish. However, they were prepared only on certain days. In our country, eggs were added to complex dishes no earlier than in the 19th century. Today this product is very popular in Russia, of course. After all, the eggs actually have a lot of useful properties. However, they can show their best qualities only if properly stored. Stale eggs can not be eaten, of course, in any case. Such a product can cause very serious poisoning.
Temperature
It is believed that the optimal egg storage temperature is -2 - +20 ° . Under such conditions, this product will remain fresh for some time before eating. Of course, like with any other food, the shelf life of eggs directly depends on the ambient temperature. The lower it is, the longer you can not eat a product of this variety purchased in a store.
According to the requirements of GOST 31654-2012, table eggs can be stored:
How much can be stored in the refrigerator
In stock, almost any housewife has eggs. And they are kept, of course, most often in the refrigerator. That is, in most cases, the egg storage temperature at home is + 2-4 ° C. Under such conditions, this product is able to maintain its freshness for a very long time. It is believed that you can keep eggs in the refrigerator for up to a month. In many cases, at this temperature, they do not disappear even within 2-3 months.
Is it possible to store eggs at room temperature
Sometimes it happens that it is not possible to put eggs purchased or collected in a chicken coop in the refrigerator. After all, such a technique, for example, may fail or be filled with other products.
Eggs, such as milk or meat, for example, are not perishable foods. Therefore, in the absence of a refrigerator, they can be kept for some time and, for example, in a kitchen cabinet at room temperature. Egg storage under such conditions, according to the standards, is possible for 25 days. However, the air in the room, of course, should not be warmed above 20 ° C.
Thus, the answer to the question of whether it is possible to store eggs not in the refrigerator, experts give a positive. But still, the air temperature in the room when using this method should not exceed +25 ° C. At this temperature, this product is able to remain fresh for a couple of weeks. Warmer indoor air can cause the start of the incubation period. Embryos, for example, in fertilized eggs develop already at a temperature of +36 ° C.
Important
The above dates, of course, may be valid only for recently collected eggs. A store-bought product at home, of course, will be stored less. Indeed, from the assembly of such eggs to the moment when they get on the counter, quite a lot of time can pass. In addition, in the supermarkets themselves, this product often lies for a long time.
At room temperature, of course, it is best to keep eggs away from all kinds of heating appliances. For this product in the apartment is to find the coolest and preferably a dark place. Most often, the eggs in the house are kept in drawers of kitchen cabinets or in the pantry.
During long-term storage in the refrigerator or at room temperature, even provided that the requirements of GOST are met with regard to the terms, this product still slightly changes its qualities over time. In fact, eggs are considered fresh only for 9 days after collection. Such a product, if desired, can be boiled soft-boiled or in a bag. If the eggs were stored in the refrigerator or in the room for more than 9 days, it’s better to cook them only hard-boiled. Thus, the risk of poisoning can be eliminated.
How fresh eggs differ from long-collected eggs
How to store eggs is thus understandable. It is best to keep this product in the refrigerator at a temperature of 0 to +8 ° C. But how can one distinguish fresh from laid eggs long ago? This is actually not too difficult to do.
In order to find out when the eggs were collected at the poultry farm, you just need to look at the markings. Stamps with the date of production at such enterprises are placed on each egg.
Also, to determine the freshness of this product, you can see it in the lumen in an ovoscope. Such a device is available in many villagers involved in breeding chickens and incubating chickens. If the yolk in the translucent egg is in the middle, then it is fresh and can be eaten soft-boiled or in a pouch.
If under the ovoscope it is visible that there are blackouts in the yolk next to the protein - this means that the egg, after it has been laid, has lain for about at least a week. Such a product can also be eaten, but preferably only hard-boiled. Stale chicken eggs will not be visible under the ovoscope. There is such a product, of course, not worth it.
Also, to determine the freshness, the egg can be immersed in a glass of water. If it drowns and lies at the bottom - it means that it was demolished only a few days ago. If the egg touches the bottom only with a sharp end - its “age” is about a week. Of course, such a product can also be considered fresh. If the egg drowns only until the middle of the glass, it will be 2-3 weeks old, and you can still eat it. If it floats on the surface, then it is rotten and it remains only to throw it away.
Boiled product
Of course, many housewives are interested in how to properly store boiled eggs. In its raw form, thus, even at room temperature, such a product may remain fresh for a long time. Being cooked, the eggs to some extent lose this property. After heat treatment, it is advisable to store such food only in the refrigerator. Under room conditions, the eggshell will remain fresh for about 3 days (at a temperature not exceeding +20 ° C).
In the refrigerator, at a temperature from +2 ° to +4 ° , such a cooked product can be kept for up to a week. Moreover, in airtight containers under the same conditions, the storage of eggs is possible for up to 14 days.
An exception in this case are soft-boiled eggs. They deteriorate much faster than hard-boiled ones. In room conditions, such eggs can lie until freshness is lost for no longer than 24 hours. They can be stored in the refrigerator for a maximum of 2 days. That is why on Easter eggs are recommended to be boiled exclusively soft-boiled. After all, lying on a plate with easter Easter eggs in the future will have quite a long time. Soft-boiled eggs under such conditions are likely to disappear. In any case, eating them will be unsafe.
Hard-boiled Easter eggs, by the way, can be stored a little longer than ordinary boiled ones. The fact is that the paint used to shape the Easter eggs clogs the pores in the shell. As a result, microorganisms that contribute to spoilage of the contents of the egg cannot penetrate inside it longer. Pysanka can be stored up to 4 days.
A similar method can be used, if necessary, so that ordinary boiled eggs stay fresh longer. To extend their shelf life, their shells simply need to be greased with vegetable oil.
How much can you store boiled eggs without shells or cracked
Such a product, of course, will lose its freshness very quickly. Eggs without shells or cracked during cooking in room conditions can be stored for no more than 12 hours. In the refrigerator, such a product will lie until freshness is lost for 1 day.
How long are quail eggs stored
This product is also quite popular with the Russian consumer. Quail eggs are more expensive than chicken. However, they also contain more vitamins and substances useful for the human body. Quail eggs, like chicken, can be stored for a long enough time.
At a temperature of 0 to +8 ° C, this product remains fresh for up to 30 days. Exactly these are for GOST quail eggs. However, practice shows that this product can retain its freshness much longer. So, it is considered quite safe for quail eggs to be stored at temperatures from 0 to +4 ° C in the refrigerator for up to 2 months.
How to determine the suitability for eating
To distinguish fresh eggs from rotten eggs, of course, will not be difficult. Spoiled, such food begins to emit a very sharp and unpleasant smell of hydrogen sulfide. Also, you can not eat eggs:
A product with such symptoms will be ruined for sure. The yolk of not too fresh eggs is flat and spreading, and the protein is watery.
Egg products

Liquid egg products by the rules store:
Instead of a conclusion
Storage of eggs and egg products, at home, including, therefore, should be subject to certain rules. In any case, it is best to keep such food in the refrigerator. Under such conditions, chicken eggs must be eaten for a maximum of three months, quail eggs - two. Dry powder in the refrigerator can, according to the standard, be eaten even two years after release.
