Can you eat old eggs? Ritual recognition of damage by eggs

It can be quite difficult for many housewives to answer the question of when the eggs stored in the refrigerator were purchased. Not to mention the fact that it is not known how long they lay in the store. Therefore, the question of how to check eggs for freshness often becomes very relevant. This article will cover all the subtleties of identifying "old" eggs and talk about how to conduct simple but effective freshness tests.

Checking chicken eggs for freshness at home

Eggs are considered a valuable source of trace elements and vitamins. "Chicken caviar" is used as independent dish or prepare various dishes based on it.

But if in fresh Since this product only benefits the body, eating spoiled eggs can lead to poisoning, which leads to serious health problems, even death.

Reveal the product that was stored long time You can also in the supermarket.

So, the freshness of eggs is determined by the following criteria:

Surface structure. The shell of fresh eggs is matte and slightly rough to the touch. Old ones will stand out with a glossy sheen and turn out to be smooth.
Smell. The eggshell has the ability to absorb the smells of surrounding objects, like a sponge. If fresh food smells of lime, then over time they will attract extraneous aromas.
Sound and vibration level when shaking. If you hold a raw chicken egg to your ear and shake it gently, that case when it is fresh, there will be no extraneous sounds. Gurgling and vibration occur if the product has been stored for a long time.
Product weight. If a fresh egg weighs from 55 to 70 g, then as a result long-term storage this figure will decrease.
View of the egg in the light. If possible, you need to bring the egg to a window or lighting fixture. When the product is fresh, it will be perfectly visible, in addition, there are no dark blotches inside. And the "air chamber", located in the wide part of the egg, will be barely noticeable. The longer the product is stored, the greater this formation.
Reaction to spin. If there is a flat horizontal surface near the counter, place an egg on it and spin it with your fingers. A fresh product will quickly stop its movement, and the one that has been stored for a long time, just like the boiled one, will wrap itself in a “top”.

Every week you bring home huge packages with a variety of products presented on the shelves of markets and supermarkets. On the one hand, this makes your life much easier, and on the other hand, it complicates it, because not everyone can constantly keep in mind the expiration date of all this gastronomic variety. Remember how often you opened the refrigerator door and wondered: “How long have these products been there?” We are sure that this problem is familiar to many people firsthand. This is especially true for eggs. Although it is a very delicate product, it appearance does not change over time, and therefore it is almost impossible to determine the freshness of an egg “by eye”. Of course, it's no secret to anyone that you can break an egg and try to determine its freshness by smell, but there are other ways. Here are some ways to check the freshness of eggs:

1. Submerge the eggs in water

Place the eggs in a deep bowl cold water. If they remain lying on the bottom in a horizontal position, then they are very fresh. Eggs, slightly raised with an obtuse angle upwards, are no longer the first freshness, but can still be used in the preparation of hot dishes. Eggs that float to the surface are spoiled and should not be eaten! We recommend that you get rid of them as soon as possible.

Eggs float to the surface because, over time, the moisture inside evaporates through the shell and the resulting "free" space is replaced by air. The more air inside the egg, the higher it floats. And, of course, the older it is.

2. Check the white and yolk

Break one of the eggs and pay attention to the condition of the yolk and protein. If the yolk is convex, and the protein is viscous and tightly gathered around the yolk, the egg is very fresh. However, if the yolk is flat and the protein is liquid, this is a sign of a stale egg.

Cause: over time, protein chains ( different substances connected with each other) break up, in connection with this, in the old egg, the yolk and protein do not adhere tightly together.

3. Shake the egg

If, when shaking, you do not hear extraneous sounds, then you can safely eat the egg - it is fresh. If at the same time bursts or squelching are heard, it means that air has got inside the egg and expanded the natural air bubble. This egg is not to be eaten.

4. Pay attention to the expiration date

On the packaging of eggs there is always information about the expiration date, which should be paid close attention. The supplier guarantees that the product will remain fresh if the storage rules are followed. As a rule, eggs can be eaten for some time after the expiration date, but before that it is strongly recommended to check their freshness by the methods described above.

When eating eggs, special attention must be paid to hygiene. Pay attention to the following recommendations:

Buy only fresh eggs and use them before the expiration date.
Store eggs in the refrigerator - at temperatures below 6 ° C, Salmonella bacteria do not multiply. At room temperature their number is increasing. Please note that subsequent cooling will not save the situation.
When cooking with raw eggs, use only very fresh eggs.
Boil the eggs for at least 5 minutes in boiling water.
If the eggs have expired, then for some time they can still be eaten, but only if carefully prepared. Salmonella bacteria are killed at 70°C.
If the shell of the egg is damaged, then it must be cooked immediately. It is no longer possible to store such a product.

Where is the best place to store eggs in a Liebherr refrigerator?

Eggs can be stored in the refrigerator for a maximum of 15 days. In the zone of freshness

We buy eggs in the market or in the supermarket. Unfortunately, it is impossible to check this product for freshness right at the counter, you have to trust the stickers with the expiration date. And only at home you can understand whether fresh eggs were bought or not.

It is simply impossible to determine the freshness of eggs, which is called “by eye”. This product can lie for a long time at room temperature and no external manifestations are imperceptible. Often, buyers ask the seller how fresh the eggs are and the answer is always the same: “Fresh eggs, take them.” You can check whether the egg is really fresh by breaking it and understanding the freshness by its characteristic smell. If it is repulsive, then the egg is spoiled. But breaking eggs all in a row is not included in our plans, so we will check the freshness of eggs in other ways.

How to check the freshness of eggs in water

Take a large container, such as a saucepan. It needs to be poured cold water straight from the tap (no more than 10 cm), and then place the eggs in it. You can take turns in order not to get confused and determine the freshness of each product sequentially.

How to understand the freshness of eggs:

If the eggs fell to the bottom and do not float to the top, then you are lucky - you bought the eggs fresh, fresh.
If you see that the eggs are slightly raised with a blunt tip up, then this means that the eggs are no longer very fresh. They can still be used, but not fresh, but to cook hot dishes (pastries, scrambled eggs, scrambled eggs).
If the eggs float, then they are definitely spoiled and such a product is generally forbidden to be eaten. These eggs must be discarded immediately. Do you know why it happens that the egg floats to the surface in the water? Every day the moisture gradually evaporates and this space fills with air. The older the product, the more air it contains and therefore the eggs will float.

There is also a similar way to check eggs, you need to pour salt into the water to make the solution concentrated. You also need to lower the eggs and see: if they lie at the bottom, then the “age” of such a product is approximately from 2 to 7 days. If the egg rises with a blunt end, and the sharp one remains “glued” to the bottom, then such a product is approximately 10 days old. If the eggs float in a saline solution, then such eggs are already about 2 weeks old. If the eggs float to the surface of the salt solution and “stick out” of it, then such eggs are forbidden to be eaten, they are not fresh.

Other Ways to Check Eggs for Freshness

An egg can be broken if one of the eggs tested in water floats up, and then examine the protein and yolk. These components look like this:

if the protein is liquid, and the yolk has become flat, then the egg is not fresh;
if the protein is dense and viscous, and the yolk is convex, then the egg is fresh.

Another way to check eggs for freshness: you just need to shake the egg, if you didn’t hear anything, then the eggs can be safely eaten if you hear a “squish” or splash, as well as any other sound, this means that there is air inside, which means This egg is no longer fresh and should not be eaten.

About the expiration date and rules for storing eggs

The manufacturer always indicates the expiration date of the product on the packaging. If the eggs were stored correctly, in compliance with all the rules, then they will be fresh.

What to look for when buying eggs:

You need to buy fresh eggs, so pay attention to the expiration date of the product. If expired, don't risk it.
You need to store the eggs in a cold place - in the refrigerator at a temperature not higher than +6 o C. If you keep the eggs at home on the table, they will deteriorate faster.
Boil the eggs for at least 5 minutes.
If the expiration date has expired, then these eggs can be eaten, but only on condition that the eggs were stored in the refrigerator and you need to cook such a product at a sufficiently high temperature (from +70 ° C).
If you see that the egg has burst, then it is forbidden to store it. It is desirable to prepare something from such a product.

How to find out if an egg is spoiled immediately after purchase or at home? Mikhail

The chicken egg is an important and valuable product human diet. Hostesses like to use it as the main component different dishes. And they want this product to be always fresh and of high quality.

Chicken eggs are a popular food product that satisfies the feeling of hunger well, because it has an increased calorie content. One eaten a day becomes an indispensable source of calcium, protein, iron, vitamins of groups B, E, A, and the most valuable trace elements.

Eggs can be checked for freshness immediately after purchase or carried out simple test at home before use, when they lie down for some time in the refrigerator. To determine whether you are buying fresh eggs in the market or in a store, you must first carefully examine the surface of the shell. Recently laid chicken eggs will have a matte, non-shiny surface.

Older specimens have a glossier and smoother surface. The method is not always relevant, since dishonest sellers can sometimes wash the product before selling, which has a positive effect on the state of its appearance.

In case of difference, the seller could mix fresh and older copies. Another method is shaking the eggs. It is possible to check their condition in this way when buying in order to determine the "talker" - a product that is no longer suitable for consumption. Because if the specimen has been lying for a long time, its insides have dried up and hang out inside the shell.

How to check at home

Sometimes eggs are stored in the refrigerator for a long time. Before preparing any dish, the hostess needs to determine the freshness of the eggs. So it’s really safe to protect your health and loved ones, so that the result of using a stale product is not dangerous food poisoning.

We will not describe the complex methods of how to check the degree of lying eggs, which are associated with the use of ultraviolet radiation or temperature measurements. Let's dwell on the simplest and most affordable ways.

water way

How to check the freshness of eggs with plain water? To do this, place them in a container with liquid, poured about 10 cm, and observe. Normal product will quickly go under the water and stay at the bottom. One that has been stored for a week or more will float to the surface with a blunt end. In a situation where it drifts easily on the surface, you can be sure that it is at least 2 weeks old.

When the egg is on the surface, like a fishing rod float, it is advised to get rid of it. He must have been at least a month old. In addition to plain water, it is permissible to use saline solution. To prepare it at home, it is enough to dissolve a tablespoon of salt in 500 ml of water. There is no need to strictly observe the proportions, since it has been practically proven that old eggs will be on the surface in the shortest possible time, even if they are immersed in a liquid without salt.

It is easy to explain - under the shell there is a shell of two layers, capable of transmitting light, liquid and air. In the blunt part of the testicle there is a fugue - an empty air particle. It is necessary for the embryo during development - through it the process of gas exchange occurs. The size of the fugue increases in proportion to the shelf life of the product.

Bacteria that provoke decay also pass through this shell. After the hen lays the egg, it ceases to be sterile. The smell of a rotten product is also specific - it is the aroma of hydrogen sulfide. Eggs float to the surface, because the gases that accumulate in spoiled specimens have a lower density.

shaking

To determine the freshness of eggs in the following way, each of them is advised to first compress so that later you can feel any vibrational movements inside. Then it is gently shaken so as not to damage the shell. An unspoiled egg will not give any unusual sensations, you will not feel vibrations inside, because it is complete.

If, when squeezed tightly in your hand and shaken, something inside the egg dangles and rolls, you can be sure that such a product is unsuitable for eating. He is also popularly called a "talker", because it creates the feeling that something is hanging inside him. Shaking has one significant drawback - it does not make it possible to find out the shelf life of the egg and the specific degree of its suitability for consumption. It only allows you to select those specimens that are better to refuse to use for food.

translucence

You can check the suitability of an egg by shining it with a source with a power of about 100 watts. The transillumination method allows you to see the pugu located at the blunt end. If it is not there, the product is unspoiled. The puge does not tend to appear immediately; time must pass during which moisture evaporates, and the contents under the shell thicken. In a dietary type of product, the scare should not be more than 4 mm, and in a regular dining room - 8 - 9 mm.

A dietary specimen should have a uniform and dense yolk in consistency. When the product is translucent, the yolk should be visible in the center of each instance. In a table product, the yolk may be located somewhat to the side. But if it is close to the surface of the shell, it is better not to use such an egg for eating. When examining the product, you can sometimes see bloody inclusions.

If they are very small, then they are considered quite normal. If the drops of blood form a ring, set aside such a product, it is unusable. If blood got inside during the formation of the product, then the protein will have a pinkish tint, and the yolk will be orange-red. If dark spots are clearly visible when translucent, then pathogenic microbes began to actively multiply under the shell.

This video shows an easy way to test chicken eggs for freshness at home.

When buying chicken, you need to be able to choose it correctly, because not only how tasty the dish will turn out (for example, chicken cooked in air grill), but also the health of you and your loved ones depends on the quality of the product. Agree, it is not very pleasant to be poisoned by stale meat.

How to determine the freshness of a chicken

Therefore, every hostess, first of all, should know How to determine the freshness of a chicken. This will be discussed in this article.

Signs of stale chicken

1. Smell. This is the most important and basic criterion for determining freshness. Always trust your sense of smell and it won't let you down. Smell the chicken and determine if you smell sweet-sweet, sour, or putrid. If the chicken is already expired and has begun to deteriorate, it will smell of dampness and mold, but if it frankly smells of rot, then it’s really bad - such a chicken only has a place in a trash can.

2. Color. The chicken that has already begun to deteriorate becomes grayish or grayish-green in color. Small purple spots can often be found near the bird's anus. Remember that in fresh, high-quality chicken, the meat always has a delicate light pink color, and the skin may be slightly moist, with a yellowish tint. You can easily figure out what to eat chicken with if it is initially fresh and healthy.

3. Skin surface. Fresh chicken should be smooth and firm to the touch. If you want to check the freshness of the meat, then press it lightly so that a small indentation forms. If the meat quickly returned to its original state, and the dent disappeared, then in front of you fresh chicken. Chicken that has expired or is nearing its expiration date has loose meat, and the dent you made will remain on the surface, and such chicken is unpleasant, sticky and slimy to the touch.

How to choose a quality product

The chicken should be not only fresh, but also of high quality, not treated with third-party chemicals and not old. Try not to buy frozen chicken, as more often than not, manufacturers or sellers give it a "water injection", that is, they simply pump water into it from a syringe. As a result, the weight of the chicken increases by up to 40%. When defrosting such a product, you will find that the actual weight of the meat is much less, moreover, such a chicken is practically devoid of nutrients.

At the time of buying whole carcass pay attention to the bird's beak - it should be dry, elastic and slightly glossy. The mouth should be slightly shiny, pink and have no unpleasant odor.

You can find out whether young or old chicken is sold to you by paws. In a young bird, they are soft, whitish in color with veins and small scales. Paws old hen characterized by coarseness, yellow tint and large scales. Also, age can be determined by the brisket. In a young individual, the tip of the sternum is cartilaginous and easily bendable, as it has not yet ossified.

Avoid purchasing chicken that has a strong chlorine smell, as it is likely past its expiration date. The fact is that manufacturers often process chicken carcasses chlorine (by law, the allowable amount of chlorine should be no more than 0.004%) to increase the shelf life. If the carcass has a strong smell of this chemical, then the manufacturers have added more chlorine than usual in order to keep the shelf life as long as possible. As you understand, such a chicken cannot be eaten.

When going shopping and intending to buy poultry meat, always remember how to determine the freshness of the chicken in order to buy a really good product. Feel free to inspect and feel the chicken in the store, because your health depends on how good the product is.

Eggs are the basis for cooking various dishes which every hostess knows. In addition, they provide the body with many nutrients. But to get such an effect, you need to use only fresh products. Otherwise, you can cause serious harm to health. To protect yourself from negative consequences, you need to figure out how to check the freshness of eggs before buying and at home.

What are the dangers of stale and rotten eggs

The danger of such products lies in the likelihood of salmonella infection, which provokes food poisoning and the development of salmonellosis. This disease is quite dangerous and in the absence of timely treatment can lead to death. But this only applies to chicken eggs. Quails lay at a temperature of 40 ̊С, and in these conditions the bacteria that cause salmonellosis do not survive.

But the following danger is typical for both types of eggs, since, regardless of origin, they are a source of allergens. But if at the dietary stage (up to 7 days after demolition) the likelihood of an undesirable reaction of the body is minimal, then as the shelf life increases, it increases.

Important! Stale eggs often provoke allergic reactions.

How long does the product stay fresh?

For better storage of eggs, certain conditions should be provided.

Only fresh products can be useful for our body. To protect yourself from possible negative consequences, you should understand the optimal shelf life of eggs.

Table: terms and conditions for storing eggs at home

Checking freshness in the store

In a store or market, you can check the external data and sound

You can determine the degree of freshness of eggs in a store or market by visual signs, smell and sound. Start by inspecting the shell: in a fresh product, it has a rough and matte surface. This applies to both chicken and quail eggs. Spoiled ones will have a noticeable shine.

Important! The presence of cracks or other damage on the surface is unacceptable.

Next, take the egg in your hand and shake it. You should not hear any sounds while doing this. If the egg gurgles, you should refrain from acquiring it. The shell of a fresh product has an odor reminiscent of lime. If it is missing, it is likely that the eggs have been stored for quite a long time. Their shell intensively absorbs the odors of the surrounding products.

Important! If the smell of hydrogen sulfide emanates from the product, this indicates the process of protein decay, that is, the egg is already rotten.

If there is an electronic scale in the store, the suitability of the product for consumption can be determined by weight. Mass of fresh chicken eggs ranges from 35 to 75 g, depending on the category, quail - 12 g. Lower weight indicators indicate their depravity.

Eggs that are too light in weight are spoiled

You can also check using a special device - an ovoscope, which is designed to translucent eggs. The location of the yolk in the center indicates the freshness of the product. If there are dark areas near the protein, this indicates that the egg has been lying for a week or two, but at the same time it is suitable for consumption. Spoiled products do not shine through at all.

Using an ovoscope will give the most accurate result.

Home methods for determining suitability

There are several ways to ensure the freshness of products at home. They are suitable for both quail and chicken eggs.

into the light

Hold the egg up to a 100 watt or more lamp and examine it. If you notice an air gap between the shell and the film located under it, then the product is not quite fresh. The allowable size of the pug (this is the name of this formation) is 9 mm and 4 mm (for chicken and quail eggs, respectively). If the layer is more than these indicators, they should not be used.
Note also the presence of drops of blood. Point and mobile formations are harmless, they occur when the chicken oviduct is damaged. But if you see a blood ring, which is the circulatory system of a dead fetus, you cannot use the product.
The multiplication of microorganisms leads to the formation of dark spots. They can also be detected by translucent eggs. The use of such products is permissible after heat treatment. But it is better not to risk and throw away these eggs.
If you have an ultraviolet lamp at home, try it in action. Enlighten the product and carefully examine the color of the contents. At fresh chicken and quail egg should be a rich red hue, while the spoiled one should be lavender or gray.

We use water

A spoiled egg will rise up

To check with the following method, you will need a glass, which must be filled with water to a level of at least 10 cm. A deep bowl is also suitable. Dip the egg into the container and watch its position. If it sinks to the bottom, then the product is fresh, and if it floats, it is unusable.

Important! A fresh quail egg will sink to the bottom, while lying sideways.

A chicken egg with an expiration date will sink to the bottom with one end, and the other will be located on top. It must be consumed in the near future and only in boiled form or used for baking.

Important! Some housewives add salt to the water, being of the opinion that such a solution will provide a more accurate result. But this method is not very efficient.

Video: water test master class

Visual inspection of content

Crack the egg onto a flat plate. Without fear, you can use a product with a convex round yolk and protein that retains its shape. A spoiled egg begins to spread.

If the yolk has acquired a bright orange color, blood has got into it at the formation stage. Do not refuse such eggs: after heat treatment, they become safe. They are used to make pancakes, pancakes, cutlets.

Important! In a spoiled egg, the protein becomes liquid, and the yolk becomes flat.

On the left is a fresh egg ( thick protein and a convex yolk), and on the right - stale (because it has no shape and spreads)

Alternative ways

Pay attention to the labeling. If the eggs contain the date of its application, they are classified as dietary, that is, they were laid no more than 7 days ago. The absence of this information indicates that the product belongs to the table type. These are eggs that are already stored for 7-25 days.

Important! Another way is to check by determining the temperature of the egg using the tongue. The product is applied alternately with a sharp and blunt end. The spoilage of the egg is indicated by the same temperature at both ends. In a fresh product, the sharp edge is colder than the dull one. But this method cannot be called reliably effective.

What to do if already welded

Fresh eggs after cooking smell good and are difficult to peel.

Determining how fresh a boiled egg is is also quite simple:

It needs to be cleaned first . The shell is removed from a fresh egg with difficulty, it is easily separated from a stale product.
Then cut it. The presence on the yolk of dark blue or green spots is a sign that the egg is not fresh.
Also here you can apply the method that is used to raw eggs and sniff them. If there is a smell of hydrogen sulfide, the use of such a product in food must be discarded.

Video: how to avoid buying a spoiled quail egg

Compliance simple recommendations help to avoid the use of stale product. To eliminate the possibility of harmful bacteria in food, be sure to wash the egg before using it. This advice is especially relevant if there are remains of blood, feathers or droppings on the surface of the shell. And in the process of preparing the dish, first break the product into a plate and make sure that there are no impurities and unwanted odors.

If you've forgotten how long eggs keep in your fridge, you can spend a few simple tests for freshness:

shaking

If you hear "squishing" sounds when shaking, then the air chamber has already reached a large size and the protein has become watery. The yolk "tumbles" in the egg if it is not too fresh.

breaking up

Crack an egg onto a plate.

Fresh eggs have a high bulging yolk holding a ring of albumen. If the yolk is flat and the watery white is spreading on the plate, the egg is not particularly fresh, it needs to be quickly processed in the kitchen.

Immersion in water

Put the egg in tumbler with water. Very fresh eggs will remain at the bottom. Week-old eggs will be angled flat end up. If the egg floats on the surface of the water, then it is already at least three weeks old. The air chamber of this egg has reached such a size that the egg floats.

translucence

Hold the egg, the freshness of which you doubt, to a bright light source so that the light falls from behind. Fresh raw eggs let in light.

No matter how you turn the egg, the yolk is always centered. In older eggs, the yolk begins to "wander".

And finally some more interesting facts

Do brown hens lay brown eggs?

But no! The color of a hen's plumage has nothing to do with the color of the eggs. The color of the egg shell depends only on the genes of the chicken.

Do brown eggs taste better?

And again you are on the wrong track! The taste of eggs is directly dependent on the feed and the health of the chicken. Under equal conditions, differences in taste and nutritional value of white and brown eggs no.

The problem of food freshness is observed not only in spontaneous markets, but also in supermarkets "with a name". And if most products have an expiration date, then there is a category of products where you have to determine the freshness “by eye”. First of all, this semi-finished meat products and, of course, eggs. Eating spoiled eggs can lead to both indigestion and more serious diseases that can only be treated in a hospital. To avoid negative consequences, we suggest considering the differences between a fresh egg and a rotten one.

Signs of freshness of unbroken eggs

The easiest way to recognize a rotten egg is to sniff it. Rotten eggs have a characteristic bad smell, which is difficult to confuse with anything. The second sign is a soft shell. When shaking, the yolk should not be felt in the egg, knocking or beating against the walls, otherwise the egg is rotten.

The yolk is clearly visible in the light in a fresh egg. You can also spin the egg on a flat surface: a rotten egg (because it is lighter) will spin for a long time, and a fresh one will stop quickly.

There is another good old-fashioned way to distinguish a fresh egg from a rotten one, based, by the way, on the laws of physics. A fresh egg is heavier than a rotten one, and if you pour 3/4 into a glass of water and lower the egg there, it will quickly sink, but this only applies to eggs no older than three days. Eggs that are a week old will be upright in the water, but a rotten egg will remain on the surface.

Of course, not all of these ways you can check the eggs in the store. In this case, you need to pay attention to the variety of eggs. Because it depends not only on the weight of the eggs, but also on when they were laid. The highest grade includes eggs that were laid three days ago, the first - a week ago and the second - three weeks ago. There is another way to check, available to advanced buyers of modern supermarkets - to check the egg with a special device - an ovoscope. This device illuminates the eggs, and in the "old" ones, a dark yolk immediately becomes visible, which is close to the shell or even sticks to it, or a large air chamber.

Signs of freshness in broken eggs

After breaking the egg, carefully look at the yolk. If the yolk is convex and tight, then the egg is fresh, laid a few days ago. A stale egg (three weeks old) has a flat, yolk, and the white is watery.

A boiled fresh egg is difficult to peel, and a spoiled one is easy.

Findings site

A rotten egg has a characteristic odor; a fresh egg has no odor.
In a rotten egg, the yolk beats against the walls when shaking; when shaking a fresh egg, no extraneous sounds are heard.
When unwinding shady egg will spin for a long time, fresh will quickly stop.
Spoiled eggs float in water, while fresh eggs sink.
The freshest eggs are assigned the highest grade, those that are not older than a week - the first, and three weeks old - the second.
If you determine the freshness with an ovoscope, rotten eggs will have a large air chamber, a dark yolk.
When broken, a fresh egg has a convex yolk, a stale egg has a watery protein and a flat yolk.
If the egg is boiled, then the fresh one will be poorly cleaned, and the “older” one will be easy.

Every week you bring home huge packages with a variety of products presented on the shelves of markets and supermarkets. On the one hand, this makes your life much easier, and on the other hand, it complicates it, because not everyone can constantly keep in mind the expiration date of all this gastronomic variety. Remember how often you opened the refrigerator door and wondered: “How long have these products been there?” We are sure that this problem is familiar to many people firsthand. This is especially true for eggs. Despite the fact that this is a very delicate product, its appearance does not change over time, and therefore it is almost impossible to determine the freshness of an egg “by eye”. Of course, it's no secret to anyone that you can break an egg and try to determine its freshness by smell, but there are other ways. Here are some ways to check the freshness of eggs:

1. Submerge the eggs in water

Place the eggs in a deep bowl of cold water. If they remain lying on the bottom in a horizontal position, then they are very fresh. Eggs, slightly raised with an obtuse angle upwards, are no longer the first freshness, but can still be used in the preparation of hot dishes. Eggs that float to the surface are spoiled and should not be eaten! We recommend that you get rid of them as soon as possible.

2. Check the white and yolk

Cause: over time, protein chains (different substances associated with each other) break down, in connection with this, in an old egg, the yolk and protein do not adhere tightly together.

3. Shake the egg

4. Pay attention to the expiration date

When eating eggs, special attention must be paid to hygiene. Pay attention to the following recommendations:

Buy only fresh eggs and use them before the expiration date.
Store eggs in the refrigerator - at temperatures below 6 ° C, Salmonella bacteria do not multiply. At room temperature, their number increases. Please note that subsequent cooling will not save the situation.
When cooking with raw eggs, use only very fresh eggs.
Boil the eggs for at least 5 minutes in boiling water.
If the eggs have expired, then for some time they can still be eaten, but only if carefully prepared. Salmonella bacteria are killed at 70°C.
If the shell of the egg is damaged, then it must be cooked immediately. It is no longer possible to store such a product.

Where is the best place to store eggs in a Liebherr refrigerator?

Eggs can be stored in the refrigerator for a maximum of 15 days. In the zone of freshness
