Shelf life of chicken eggs in the refrigerator

Introduction

Chicken eggs appeared over 2.5 thousand years ago in a small Indian town. In European countries, eggs appeared a little later and fell to the taste of the Romans.

Nowadays, eggs are one of the simplest and most delicious foods. However, in ancient times, eggs were treated in a very unusual way. In Russia, chicken eggs were cooked only at a certain time. In those days, the egg in Russian cuisine was perceived as a separate dish, and only in the 19th century it began to be used for preparing other food products.

The egg had a special meaning in Easter ceremonies. They were illuminated in churches, carried to the graves of deceased loved ones, and were "christened."

It was also customary to beat with eggs in order to show "who is in charge here."

In village families, on the first Easter day, wheat was poured into a small container on the table and an Easter egg was hidden inside. Subsequently, these seeds were sown in the fields.

And the tradition of dyeing eggs for Easter appeared in the days of the pagans, for whom the red egg symbolized the sun, helping nature to wake up after a long winter.

Permissible temperature according to SanPiN

According to GOST R 52121-2003, in order for chicken eggs to remain edible and retain all their useful properties, they must be kept:

in thermal mode from 0 ° С to 20 ° С no more than 25 days;
when the temperature drops from 0 ° С to minus 2 ° С, their shelf life is 90 days.

Usually, in a home refrigerator, space is allocated on the door for storing eggs. In this case, it should be borne in mind that the door is the warmest part of it and the temperature in this zone ranges from +8 ° С to + 10 ° С. This thermal regime is registered by SanPiN as suitable for raw eggs and preserving their positive qualities for up to one calendar month.

If there are a lot of eggs and you need to extend their shelf life, then you should choose a compartment called the freshness zone or zero chamber - a compartment located directly above the trays for vegetables and fruits. There the refrigerator maintains the temperature from 0 ° C to + 2 ° C. But it is not recommended to abuse storage and keep them there for three months.

Frequent opening of the refrigerator door leads to temperature changes, which is also harmful to maintain freshness. The safest way is to put the eggs in a cardboard box, which allows air to pass through and keeps the cooling temperature around the eggs.

How to store boiled eggs

It is preferable to store washed, boiled eggs in the shell in the refrigerator. At low above zero temperatures, the beneficial properties, taste of the dish are better preserved, the risk of poisoning or contracting intestinal infections decreases in the first couple of weeks after cooking.

The maximum shelf life of the QW at room temperature is not higher than +20 ° C - 2 days, but the duration depends on the temperature treatment and the condition of the product. Unpeeled hard-boiled eggs remain usable longer. If this dish is soft-boiled or "in a bag", without shells or with cracks - eat it within 10-12 hours after heat treatment. In a hot room, food can deteriorate even faster, in 5-8 hours.

At room temperature

In the heat, the animal product quickly decomposes and turns into an inedible mass. If it is not possible to transfer it to the coolness, wrap it in foil or put it in a thermos, transfer it to the shade.

As an alternative to coolness, the product is immersed in a saline solution - 20 g of crystals per liter of water - or a lime "shell" is made. The QW is boiled and lowered into a container with the sharp end down. Pour slaked lime on top and allow the composition to dry. In salt, the workpiece will lie for up to a month, in the "shell" - up to 4, but it will acquire a specific smell.

How much to store boiled eggs in the refrigerator

To extend the shelf life without salt and lime, you need to find out how much a boiled egg can be stored in the refrigerator. After heat treatment, the still hot specimens are removed from the water, transferred to a paper towel and left for a couple of minutes.

When the moisture remaining on the surface has evaporated, put it in a sealed container and put it back into the refrigerator. Move from the QY door - heat and temperature drops due to constant openings and closings will spoil the workpiece. Keep container away from food with strong odors and raw foods like meat, fish.

Egg storage method

In the freezer

It is rarely sent to the KYa chest freezer - the value of the frozen workpiece is lost, the taste changes for the worse. If you want to preserve the product, peel and collect the yolks in a glass or plastic container with a lid. Place the container in the freezer and use it throughout the year. Protein will have to be eaten right away.

Protein will have to be eaten right away.

In addition to the freshness and duration of heat treatment, the type of eggs also affects the SH. The caesarians retain the longest fit for human consumption - thanks to their thick, dense shell. Quail are considered relatively less persistent - they go out faster than the latter due to their size, and chicken ones are already referred to as relatively perishable.

After Easter

Faith and the Easter miracle of the CX product do not prolong, you will have to eat the cooked for the period corresponding to the conditions. To increase the time during which the EPs remain incoming for food, tricks help:

Boil eggs as fresh as possible. Look for those that were taken from chickens 1-2 days ago.
Thermally process purchased items on a holiday. Get up early and cook for Easter, not ahead of time.
Boil for at least 15 minutes. The protein may turn out to be "rubbery", the yolk - acquire a gray tint, but the microorganisms will die.
Use natural dyes. Orange-reddish gives the husk of onions, yellow - the juice of carrots fried in butter, red - beets. Green can be obtained from spinach, and blue can be obtained from a mixture of blueberry juice and baking soda.

Try not to peel the ones you don't plan to eat quickly, and put the dish in a cool place.

It is better to store unpeeled eggs

Quail eggs

The rules for storing quail eggs do not differ from chicken eggs: put them in a plastic container with a lid or a paper bag, put them on the back of the refrigerator. The difference in terms is that a product with a whole shell will lie in coolness for a week, at room temperature - 12 hours. Burst and peeled ones will have to be eaten 2 times faster.

Store quail eggs in a paper bag

Purified

Lack of shell or damage increases the risk that pathogenic flora will multiply inside the QW. And specimens decompose faster - in the heat they dry out in 6-10 hours. At + 6… + 20 ° С the dish remains edible up to 12 hours. At 0 ... + 4 ° С, eat it in 2 days.

Peeled eggs are best consumed in the first 12 hours.

Storage advice

Eggs are used in cooking, often as a main ingredient (for example, in baking)

That is why it is important for every housewife to know about the storage conditions of such a product. Based on the norms according to SanPiN, it can be argued that raw chicken eggs are stored in the refrigerator at an optimal temperature of no more than +6 ℃ for the following period:

canteens (from the store) - up to 25 days;
dietary - up to 7 days;
homemade - up to 3 months.

The best place to put fresh eggs in the refrigerator is the lower compartment (chilled room) for fruits and vegetables.It is there that the most stable temperature and humidity are observed. But do not put eggs in several rows, so that later you do not collect the broken ones from below.

It is recommended to store eggs in a "fixed" position, separate from products with a pungent smell.

It is recommended to store eggs in a “fixed” position, separate from other foods, especially those with a pungent smell. This is due to the porous structure of the shell, which is why foreign aromas are quickly absorbed through it. Also, through micropores, an infection from contaminated foods, such as meat or fish, can enter the egg. To avoid such a nuisance, the pores in the shell can be "closed" by wiping it with vegetable oil.

By the way, before placing the eggs in the refrigerator, you do not need to subject them to additional processing, because the shell reliably protects the white and yolk from external influences.

Many are interested in how many raw eggs are stored in the refrigerator, if they are goose or duck eggs. The answer is no more than 2 weeks. Raw quail eggs last longer in the refrigerator - up to 2 months. This is due to the presence in their composition of a special amino acid lysozyme, which is capable of fighting bacteria and microbes. The shelf life of quail eggs can be extended by placing them in a closed container (tray or container).

It is better to store eggs in a cool place with the tip down, so that the yolk is located away from the air chamber. This will keep it fresh longer.

How to store boiled eggs

There are several factors regarding the shelf life and shelf life of eggs:

processing quality - hard boiled or in a bag (poached);
the integrity of the shell - processing only clean and whole specimens that need to be dipped in boiling water after they lie outside the refrigerator for 5-10 minutes;
production date, freshness;
storage.

Boiled eggs can be cooked hard-boiled or in a bag. The best chances of lasting the longest are hard-boiled products with intact shells, which are stored in the refrigerator. In this case, the shelf life will be from two to three weeks. Much less, only 48-60 hours, a whole hard-boiled egg will last at room temperature.

A specimen with a tough yolk in a cracked state will lie in the refrigerator for four days, and without a shell - only 12 hours. At room temperature, the period of use with any condition of the shell should not exceed 12 hours.

The storage standards are as follows. A product with a whole shell, but in a bag, will "live" no more than two dray in the refrigerator and 12 hours outside its cool dark walls. A soft-boiled product with or without cracked shells in any space will be suitable for only 8 hours. Then the process of damage will begin.

How to boil an egg to extend its shelf life

If the goal is to extend the shelf life of a boiled egg, it is important to properly process it with hot water. Just 10-11 minutes of cooking is enough to change the structure, taste and destroy pathogenic microbes and bacteria, including salmonella

All of the above is a guarantee of the longest possible storage.

A product cooked in a bag, that is, kept in boiling water for 5 to 8 minutes, should be eaten within two days after heat treatment. Even if kept in the refrigerator.

Which eggs last longer?

For long-term storage, eggs are exceptionally fresh, freshly harvested in cool conditions with a strong shell, on which there are no potholes or small cracks. When collecting the product, markings are left with a simple pencil, indicating the date for further tracking the expiration date. The shell is not washed and is covered with melted lard or fat to protect it from external influences.

Prepared fresh eggs are left in a room where the temperature is stable during winter.

In this case, it is important to exclude freezing. For the product to be stored for a long time, the room must be dark

Alternatively, drawers or boxes can be tightly closed to further restrict air access and maintain freshness.

Quail and chicken - is there a difference?

Quail eggs are considered the most common after chicken eggs. This variety has individual properties, is characterized by reduced size and weight. A characteristic external feature is a monochrome color interspersed. Quail products are often used for cooking and making exquisite sauces of high gastronomy.

The relatively small size has a negative effect on the ability to long-term storage. It is not recommended to consume the product raw and half-baked after 10 days of storage.

Which eggs are stored longer

If the eggs are laid by their own chickens or purchased from familiar farmers, they are stored for about 3 months. Purchased in the store, it is advisable to use within 30 days. Consider also the storage conditions: eggs placed in the refrigerator will stay fresh longer. Raw ones lie at least 30 days, hard-boiled - about a week, soft-boiled - no more than 48 hours. If you see a crack in the shell, eat the egg within 24 hours. The shelf life may depend on the category and color of the shell. According to the law, dietary ones must be put up for sale no later than 7 days from the date of demolition, canteens - 25 days

Also note that brown shells are denser than white shells, so they last longer.

Egg storage tanks

The compartments with compartments in the refrigerator doors are not suitable. You can take them out, put them on the shelf

It is important not to keep dirty eggs near boiled sausages, meat, chicken. When you open the door, a draft appears, microbes scatter around the chamber

It is advisable to pack the rest of the products. In the absence of mobile plates with cells, we recommend using egg trays, find other dishes.

Suitable container:

stand with dividers;
trays with dividers;
cardboard cassettes with cells;
bowls, buckets without a lid.

Doesn't fit:

sealed containers;
plastic dishes;
plastic bags.

Do not cover containers with foil, use too high dishes, fill large buckets. Ensure free air circulation.

Useful properties of boiled eggs

However, among the variety of boiled eggs, soft-boiled eggs are the most useful, since raw yolks are better absorbed by the body.

Boiled eggs are recommended for the prevention of tumors and the protection of the heart and blood vessels. Frequent consumption of boiled chicken eggs will strengthen nails, teeth and bones, have a positive effect on vision, brain, nervous and digestive systems. Eggs are very useful for athletes to improve their muscles.

Eggs are considered more than just a nutritious food with an abundance of protein. They are also recommended for use by sick people, as well as those who regularly follow various diets. Of course, healthy people are happy to eat eggs. And despite the fact that it is fresh eggs that retain all the most useful properties, however, in most cases, people prefer boiled eggs.

How to determine the freshness of a boiled egg

The above CXs are conditional and depend on many specific factors. Before starting a meal, it is better to determine freshness by the appearance and smell of the workpiece, otherwise the risk of poisoning remains.

Focus on 4 signs:

The aroma matches the edible boiled QW. The rotten ones have a strong unpleasant odor, which is felt even through the shell. If you have the slightest doubt, send the cooked food to the trash can or to feed the birds.
The egg is firm to the touch, without mucus, stickiness and excess liquid. Water inside the shell indicates damage prior to cooking. Mucus is formed during the decay of the product, usually combined with an unpleasant odor.
The protein is uniformly colored, of the corresponding color. Free from stains that indicate damage to the cover or deterioration and foreign inclusions.In rotten QW, it acquires a grayish tint. A similar one in the yolk is a sign of prolonged heat treatment. In a rotten product, the middle turns black.
In eggs that have lain, the yolk looks dry. The middle has an unusual loose texture, does not disintegrate into flakes, but looks more like a dense sticky mass.

What affects the shelf life of eggs

The storage time for boiled chicken eggs (EC) depends on 5 factors.

Freshness of the product before heat treatment

The earlier the egg gets on the table from the chicken, the longer it will be possible to store the boiled one. The causative agents of salmonellosis in a fresh product are more often found in the dirt on the shell, but over time the bacteria find themselves inside and die only after prolonged heat treatment. Look at the production date of the product on the packaging and each piece and try not to buy copies older than 7-10 days.

Storage conditions for raw eggs

Without a refrigerator, a product labeled "dietary" will stay for a week, "table" - 25 days. At a temperature of + 2 ... + 4 ° C, the shelf life of the latter increases to 90 days. Please note that the indicated temperature range corresponds to the main compartments of the refrigerator.

It is a couple of degrees warmer on the door, eggs in the intended tray are stored worse. If you want to use the product in a month, transfer it to the “freshness zone”, where the temperature is maintained at 0 ° C.

Egg freshness test

Shell condition

Open the packaging in the store and examine each EP. There should be no cracks on the surface. With damage, the risk of bacteria being trapped in the protein and yolk increases. If you didn't notice and bought it, eat the cracked specimens first, do not keep it for a long time even at low temperatures. If you break it often during transportation, choose a brown shell, which is thicker and stronger than white.

Duration and method of cooking

It is best to cook hard boiled eggs for 15 minutes. Boil already washed - with vegetable and fruit detergent or baking soda. For preparation, the QW is immersed in cold water. Hot shells may crack due to temperature changes. Eat a soft-boiled dish as soon as possible. Do not leave for longer than 2 days at low temperatures and 12 hours in a warm place.

Duration of boiling eggs

Storage conditions for cooked eggs

The longest shelf life (CX) is in the freezer. The taste will change after freezing, the texture will become "rubbery", but in extreme cases, the method can also be used. Slightly fewer QWs lie in the back of the refrigerator, even less on the door and at room temperature.

The difference in CX due to different conditions is described in the table.

Condition after heat treatment	Shell	Where lies	How many days are stored
Hard-boiled	Whole	In the cool	14-20
Warm	2-3
Damaged	12 hours
In the cool	0,5-4
Soft-boiled	8 ocloc'k
Warm
Whole	12 hours
In the cool	2

Egg characteristics

Depending on the weight, eggs are divided into several types:

How to choose the right one

To extend the shelf life, it is worth paying particular attention to the choice of this product:

It is permissible to buy such food only from those sellers who can provide a quality certificate. Thanks to this, it will be possible to prevent the unwanted consequences of the purchase in the form of poisoning.
Before purchasing, you should definitely study the condition of the product. There should be no cracks or other damage on it. It should be borne in mind that the shell of quail eggs is considered more fragile in comparison with chicken eggs. Therefore, it is often damaged.
The purity of the product is of great importance. Slight contamination may be present on the surface. However, cleanliness suggests that sellers control the quality of products and are responsible for their business.

How to extend the shelf life?

We decided on the shelf life of raw, damaged, "opened" and boiled eggs, learned how to determine their freshness. Now there is a useful life hack: how to extend the shelf life of such a product. Is it possible?

Of course yes! And the way here is quite simple and logical - to use freezing, which is so successfully used in relation to other products. As practice shows, you can freeze both whole undamaged eggs and separated from each other yolks and whites. In this case, the shelf life increases more than significantly - up to 1 year!

But here we must remember that egg yolks have a tendency to thicken when frozen. To prevent this from happening, add either 1/8 teaspoon of salt or 1.5 teaspoon of sugar for every four yolks.

Do not be afraid if, after defrosting, the product slightly changes its structure, it will behave a little differently during cooking. These "side effects" of storage do not make it inedible or unsafe to eat.

It is not always necessary to trust the information that the manufacturer indicates on the product packaging. The standard shelf life of the same eggs in proper conditions is at least 3 weeks. If you still doubt their freshness, try a cold water test - a rotten egg will float. The shelf life of a product can be increased by freezing it. Eggs can be stored in this way even for about a year.

How to keep freshly picked raw at home?

In everyday life, as a rule, there are two ways of storing:

in fridge;
in room.

In the refrigerator, you need to set 1-2 degrees. This is the best temperature for good storage. Homemade eggs can be stored in the refrigerator for up to three months. Store shops should not be kept longer than one month.

A common mistake people make is laying eggs in special containers installed on the refrigerator doors. This arrangement is not suitable for long-term storage. Why?

Firstly, it is harmful for eggs to transfer and wobble. And this happens every time the door opens.
Secondly, the temperature and humidity on the door shelves constantly change upon opening, which also negatively affects them.

IMPORTANT: Eggs must be placed in the lower container. They are usually intended for fruits and vegetables, but they are also suitable for eggs.

Low temperature and humidity are kept there as stable as possible.

But this does not mean that it is forbidden to place our products on the door. You can put them there, provided that they will be used in the near future. At room temperature, shelf life is reduced to three weeks

At the same time, it is important that the eggs are raw and freshly harvested.

The maximum temperature can be up to 20 degrees. The relative humidity for such storage should be 70-85%. For best storage, eggs can be wrapped in paper. It can be newspaper, office paper, baking paper, etc. Other housewives are more creative.

Saline solution is their main friend in this business. Salt has long been recognized as a preservative. To prepare it, you need 1 liter. water and 1 tbsp. l. salt.The eggs are immersed in this solution and sent to a place where no light rays fall. This miracle solution can be stored for up to four weeks.

All of the above rules apply only to raw eggs. Boiled eggs deteriorate faster. A heat-treated egg can be kept in the refrigerator for up to 15 days. If the shell is damaged during cooking, then up to 5 days.

Shelf life of raw eggs in the refrigerator

Storing raw eggs in the refrigerator is the best option in a city apartment.

If they were purchased from a store, the shelf life of the eggs will not exceed 25 days.
The home product can be stored for up to 90 days.

Here are some tips for refrigeration:

Eggs are best stored in the vegetable compartment. But if stored in this place, care must be taken to isolate the eggs from other foods. Their shell has a porous structure, and various microorganisms and odors can easily penetrate through it.
Eggs should be stored in the vegetable compartment in cardboard or plastic packaging. This will keep them from drying out. This is especially true for refrigerators with no frost technology.
Too many rows do not need to be done: the products of the lower row may not withstand the pressure and burst.
It is better to store raw eggs with the sharp side down. In this position, the yolk will be farther from the chamber with air, which will significantly extend the freshness period.
If the egg is accidentally cracked, it is poured into a glass container and stored for no more than 1 day, and boiled, without shells - 1 - 2 days.

Conditions for increasing the survival rate of chicks

Experts have found that eggs can be stored for a maximum of 5-7 days for incubation. You can store it for longer, but the percentage of hatching chicks will drop commensurately. For clarity, the following table is shown.

Shelf life (day)	Number of surviving embryos (percentage)
chickens	ducks	geese
5	91,5	85,6	79,7
10	82,4	80,0	72,6
15	70,2	73,4	53,6
20	23,4	47,1	32,5
25	15,0	6	5,0

We talked more about the terms of incubation of chicken eggs here, and you can read about the features of artificial breeding of chickens at home here.

It should be noted that the longer eggs are stored for breeding, the greater the risk of hatching sick chicks increases. Eggs have two purposes: to be a healthy and tasty food product, and to perform a reproductive function aimed at procreation.

Both in one and in the second case, it is important to ensure the correct storage conditions. Only in this way can we get decent food on the table and healthy chicks.
