Eggs occupy a special niche in our food basket. With their help, the supply of protein necessary for growth and proper cell structure is replenished. In terms of vitamin D content, eggs are second only to fish oil. They contain macro- and microelements such as calcium, phosphorus, iodine, iron, copper, cobalt, potassium, magnesium, sulfur, boron, manganese and others minerals and also rich necessary for the body human amino acids.
Chicken eggs can not only benefit the body, but also diversify our diet, which is why it is important to know the rules for storing them. After all If stored and consumed incorrectly, eggs pose a mortal danger.
For consumer safety, there is GOST, which determines the shelf life (it starts from the moment of transportation). The permissible storage time for chicken eggs is 25 days, for quail eggs – 30.
General rules
How to properly store eggs?
To increase the shelf life indicated in GOST, eggs for home use needs to be stored in a container– its walls will not allow moisture and light to pass through, and will protect against the penetration of odors.
- Keep in a dry and cool place.
- Place the sharp end down.
- If cracks or chips are present, use immediately.
- When storing without a refrigerator nearby, turn on the fan and direct a cold stream of air onto the eggs.

Industrial egg storage
As mentioned above, eggs are a relatively small product. In today's market conditions, it is simply necessary to increase this period.
IN industrial scale The following methods are used for this:
- storage at low temperatures and in a chilled state;
- in lime mortar;
- in thin synthetic films;
- using special oil coating.
All of the above methods require certain conditions to be met..
Eggs are the most famous product in the history of cooking, providing humans with high-quality protein, vitamins and microelements. Is there a way to save beneficial features eggs for as long as possible? Revealing secrets proper storage such a valuable product.
- duck
- ostrich
- quail
- chicken
- turkey
- goose
- guinea fowl
To be fair, it is worth noting that the egg of any bird is edible. The main condition is that the product must be as fresh as possible!
Important. Poisoning stale eggs occupy second place after mushrooms in food poisoning statistics
Shelf life of raw eggs
Shelf life of eggs room temperature and in the refrigerator depend on many factors.
- Storage temperature
- The optimal temperature is considered to be within 3-4⁰С
- For comparison: 1 day of storing a chicken egg at room temperature corresponds to 1 week of storage in the refrigerator
- The more stable it will be temperature regime, those longer product will retain its freshness
- Humidity
Surprisingly, eggs love moist air. This is why many cooks and poultry farmers recommend storing eggs in the refrigerator in vegetable containers. At the same time, excess moisture can cause putrefactive processes and spoil the product.
- Shell thickness
The thicker the shell and the denser the inner film of the egg, the longer it will be stored (even without refrigeration). Guinea eggs, which have a relatively thick shell, remain fresh at room temperature for more than 30 days.
- Shell integrity
The shell is an ideal shell created by nature itself. Even the most microscopic cracks that appear on it disrupt the internal balance and shorten the shelf life of the egg.
- Cleanliness of the shell: the cleaner the surface, the fewer pathogenic organisms there are on it
- But this does not mean that the eggs of non-waterfowl birds need to be washed urgently. The washed ones raw eggs shelf life is sharply reduced. This is due to the need for the egg to “breathe”. When washing eggshells the pores become clogged, which prevents the natural gas exchange of the internal contents of the egg with the environment. Eggs are washed warm water immediately before use. Heavily contaminated eggs are used first
- Eggs laid by waterfowl can and should be washed with water before storing!
- Illumination
They don't like eggs sunlight! The darker the storage location, the longer the eggs will last.
- Position
This placement of eggs is quite justified. The fact is that in the round, blunt part of the egg there is an air chamber, the so-called “puga”. Nature created the puga as an oxygen cushion for the future chick. Puga and more than 10,000 pores of the shell saturate the egg with oxygen, removing carbon dioxide and hydrogen sulfide outside the shell
This general rules, extending the shelf life of all bird eggs. About storage features individual species read below
What is the shelf life of chicken eggs in the refrigerator?
Chicken eggs remain the most popular product around the world.
If you buy eggs in a store, carefully read the labeling. It is she who will tell you how long the product you purchase can be stored, because the shelf life of dietary and table eggs is different. The explanation of the marking is shown in the photo below.
Important: do not forget to pay attention to the packaging date of the eggs
Shelf life of quail eggs in the refrigerator
Quail eggs, in comparison with chicken eggs, are smaller in size and have a thinner shell. This also leads to a shorter shelf life of the product, even in the presence of a refrigerator. So at a temperature of 18-23⁰ and in compliance with all the above rules quail egg can be stored for no more than 30 days. In the refrigerator, shelf life increases to 60 days.
Shelf life of boiled eggs
In the case of eggs, the generally accepted logic is not acceptable: heat treatment does not increase, but sharply reduces the shelf life of the product.
A boiled chicken egg remains suitable for consumption.
- at room temperature no more than 24 hours
- in the refrigerator - 3-5 days (depending on the initial freshness of the egg and the cooking method). Storage for more than 5 days worsens nutritional characteristics product. Eating boiled eggs that have been in the refrigerator for more than 10 days can be hazardous to health.
Important: this is about unpeeled boiled egg!
Why do boiled eggs last less?
It's all about the actions high temperatures, as a result of which
- the natural protection of the shell is destroyed
- the white and yolk coagulate - the process of so-called denaturation occurs
- the natural processes inside the shell are disrupted, because the main purpose of the egg is not to become breakfast
Shelf life of eggs for incubation
The main purpose of the egg is to become the cradle of new life.
How well an egg will cope with its primary task depends on the conditions of its storage. Different rules apply here
- The optimal temperature for storing eggs before incubation is 8-15⁰С, for ostrich eggs - 16-18⁰С
- Humidity - 75-80%
- Laying method
- avoid multi-tiered laying of eggs
- use special trays for laying
- Place ostrich, quail, chicken, and turkey eggs vertically, with the blunt end up. To prevent tearing and stretching of hailstones, movement of the embryo and drying out of the medium, turn the eggs from top to bottom from time to time
- store goose and duck eggs in horizontal position also, from time to time, changing their position. To avoid confusion when turning over the incubation material, mark one side of the egg with a simple pencil
- Shelf life of eggs at optimal temperature
- chicken, ostrich and quail - 6-7 days
- turkey -5-6 days
- duck - 8-10 days
- goose - 10-12 days
Features of use and shelf life of goose eggs
Waterfowl eggs are rare guests on our tables.
There are several reasons for this:
- Geese and ducks are not laying hens by definition. Their eggs are primarily used to replenish the bird population. Rejected raw materials not suitable for incubation are used in cooking
- Waterfowl eggs are usually eaten only after heat treatment due to the high risk of salmonellosis infection
- The storage conditions for eggs are almost identical to the storage conditions for chicken eggs, but the shelf life is longer due to the high density of the shell
If you are lucky enough to become the owner of a goose or duck chickens, don't be embarrassed by a new culinary experience! These products have proven themselves excellent in baked goods, omelettes, and salads.
Features of use and shelf life of ostrich eggs
The ostrich confidently conquers northern latitudes and feels great in our climate, which is far from African.
- Ostrich eggs are dietary product, while maintaining all the beneficial properties of a chicken egg
- One ostrich egg can make an omelette for 8-10 people. broken egg can be stored in a hermetically sealed container in the refrigerator for 2-3 days without losing its beneficial properties
- At room temperature, an ostrich egg can be stored for up to 30 days, provided the shell is not damaged. Refrigerated shelf life increases to 6 months
The video at the end of the article will tell you more about how long eggs should be stored.

Fresh eggs will sink to the bottom (they were laid 1-7 days ago). The eggs that have floated to the surface are old and dangerous to eat. If the eggs float underwater without rising to the surface, then they are no longer fresh, but they can still be eaten (they are 7-20 days old).
How to keep eggs fresh at room temperature?
There is no clear answer to the question of how long eggs can be stored at room temperature. Shelf life ranges from 3 weeks to 3 months depending on the chosen storage method.

If the shell is damaged during the cooking process, the shelf life of the egg is reduced to 2 days. It is better to eat peeled eggs during the day, since the shell no longer protects the white and yolk from dangerous microorganisms.
The most pleasant and rich taste eggs are laid in the first few days after they are laid by a chicken. During this period, their benefits are maximum.

Other ways to store chicken eggs
There are several interesting ways how to store eggs without refrigeration. All of them have been tested over the years and the experience of many housewives, and you can also safely take note of them.
- Grease the eggs and then place them in the box with the oats, pointed ends facing down. In this case, the eggs should not touch each other. Chicken eggs should be covered with a good layer of oats on top.
You can coat the shell with egg white. The protein is applied in two layers. Moreover, each layer dries well. Next, the eggs are wrapped in paper and sent to long-term storage to a dark place.
For long-term storage, each egg should be greased with a mixture of melted paraffin or wax with sunflower oil. - You can store eggs in a solution of potassium permanganate (potassium permanganate). To do this, prepare a bright pink solution of potassium permanganate and place chicken eggs in it for a few seconds. After this, dry them. Eggs treated with a solution of potassium permanganate can be stored in an apartment for 2-3 weeks.
It is possible to store fresh eggs at room temperature in a mixture of charcoal and bran. - IN rural areas often used for storing chicken eggs sweet water. Dilute 2 kg of sugar in 2 liters. Boil the syrup and wait until the sand is completely dissolved. When the syrup becomes warm, dip the testicles in it for 2-3 seconds, then dry them with a paper towel and place them in a box.

If you raise chickens at home, then you know that feeling when you go to collect fresh eggs and imagine how many of them you will now find in the nest. And if you’re lucky, you’ll find them still warm, freshly picked.
Do eggs need to be peeled or washed before storing?
Poultry farmers always have heated debates and opposing opinions regarding this point.
On the one hand, if you use eggs yourself, for your family and are not very squeamish, it is better to leave them dirty. And wash only immediately before use. But if you sell or treat relatives and friends, you can be sure that they will very quickly stop asking you for them.
So the first piece of advice would be: keep nests as clean and fresh as possible. Lay a thick layer of straw. Change the bedding often. To get eggs as clean as possible right away.
Unfortunately, this still does not provide a 100% guarantee that you will receive only clean eggs. Sometimes they will appear dirty. In this case, try not to get them wet, but wipe them with a dry cloth to remove any adhering dirt.
If dry cleaning is not possible, only then wash them with a soft sponge. And this should be done exclusively in warm water!
There is simple physics here: the structure of the shell is porous and allows moisture and air to pass through well. When you wash eggs in warm water- the contents expand when heated and nothing gets in. If in the cold- the contents shrink and draw dirty water inside along with pathogenic microbes.
But keep in mind that when washing, you wash away a special protective film from their surface, which protects against bacteria from penetrating inside.
How to store chicken eggs
When the eggs are collected and cleaned of dirt, the question arises of where and how to store them. Option two: Do this at room temperature or in the refrigerator. Washed ones are an exception. They definitely need to be stored in the refrigerator.
Storing fresh eggs at room temperature
Freshly picked eggs can be stored at room temperature at least a month. If you manage to eat them within a month, then there are no problems, you don’t have to load the refrigerator.
Note: This does not apply to store bought eggs! Before they hit the store shelf, they had already spent at least a month at room temperature.
Shelf life in the refrigerator fresh eggs increases many times over.
Storing fresh eggs in the refrigerator
If you are not going to think about shelf life, put them in the refrigerator.
Fresh eggs can stay in the refrigerator without any problems. 6 months. They will still taste the same as when they were just picked. The only change that occurs during long-term storage is that the protein becomes more liquid. But this does not affect the taste or any other qualities.
If you are worried about whether you have over-cooked the eggs beyond this period, simply write in pencil on each one the date it was laid.
How to preserve eggs for as long as possible
If six months is not enough for you and you need to increase the shelf life to the maximum, you will have to freeze them. But here, unfortunately, not everything is so simple. You can't just take eggs and put them in the freezer.- When frozen, they will simply burst.
To freeze them, you need to break them and separate the yolks from the whites. And only then freeze in separate containers.
Note: it is very convenient to separate the yolks from the whites using plastic bottle. Watch the video.
Of course, this method should be resorted to only in cases of truly urgent need. Once defrosted, eggs will no longer taste as good as before freezing.
Increasing shelf life using any coatings
On the Internet you can find tips for preserving eggs, where they are lubricated with oil, Vaseline, lemon or lime juice, and buried in sawdust. All this is complete nonsense, which in no way affects the duration of storage. On the contrary, it will only speed up the disappearance. So we do not recommend getting carried away with such methods.
How long can boiled eggs be stored?
- Boiled eggs can be stored at room temperature for no more than three days.
- In the refrigerator - no more than three weeks.
How to check whether an egg is good or bad without breaking it
If you accidentally find an unauthorized nest on your property where your chickens are secretly laying eggs, and you don’t know how long they have been doing this, you will need to find out whether these eggs are edible. Have they gone bad?
There are a couple of simple and effective ways to do this.
- Place the eggs in a bowl of water. If they fall to the bottom, everything is fine! They are fresh and edible. If they surfaced, then sad news. They should be thrown away.
- An even easier way to check the quality is to simply hold the egg to your ear and shake it slightly. If you hear splashes and feel something dangling inside, feel free to throw it away. It's rotten. If everything is quiet, then it’s normal, it’s fresh. If you are not sure, take a guaranteed fresh one and compare its sounds with a “suspicious” friend.
