Fresh eggs sink or float in water. Why do quail eggs float

In the section on the question If the eggs floated in the water, what does this mean? Can't they be cooked? given by the author 4uukepuk UHuhhuv the best answer is I can only supplement all the other answers: break it, see for yourself, and then you will imagine how much the egg floats and how stale it is.

Answer from Neurosis[newbie]
it is forbidden

Answer from Klava[guru]
The eggs are not very fresh. You can cook, and there it will be seen - how not fresh. Maybe it's nothing to worry about :)

Answer from luxury[guru]
Not a single fresh egg will ever float.
If the egg has surfaced, it means only one thing. It's old!
The reason lies in the fact that over time the air cavity in the egg increases.
Some boil eggs in salt water so that the shell does not burst, it is well cleaned. It is a myth.
But already a 7-10 day old egg is quite suitable for food, subject to storage conditions, in salt water it can slightly float in the water column. It has to do with density.

Answer from get christened[newbie]
They DO NOT cook! They have deteriorated. If the eggs sink in water, then they are fresh, if they float slightly, then you need to hurry up to eat them, and if they float, then they are stale. Tip: it is better to store eggs in the refrigerator with the blunt end up and the sharp end down, so they will keep their freshness longer, checked!

I think it's impossible

Answer from Liona-STRO[guru]
Rotten.

Answer from Olga Sipacheva (Demidova)[guru]
Old, dry and lighter than water.

Answer from Nosova Svetlana[guru]
Just a hundred years ago, the freshness and quality of an egg was determined precisely with the help of water. The dubious egg was simply placed in a container of water. If the egg sank to the bottom, everything is in order. This showed that the egg was quite fresh and fit for consumption even when raw.
If the egg stopped in the fall and floated somewhere in the middle of the container, it was believed that the egg had already “thought”, and it should be immediately put into use (and not in a raw form), because after a short amount of time it would become unusable.
If the egg, dipped into the water, floated up and floated in it, like ... a leaf in the hole, the conclusion was unambiguous: you should not eat such an egg. Better to throw it in the trash.
Under the shell of the egg, the processes of decay and protein decomposition begin, as a result of which gases are released (and then the putrefactive smell of hydrogen sulfide appears), which, as is known since school, is lighter than water. And the more the process of decay, the more gases, which, having combined with the air already in the egg, raise the spoiled egg to the very surface of the water. So, if the egg floats at the very neck of the water container, this means that the egg is not only old, but also rotten.

Answer from yoya[guru]
They are old, just throw away.

Answer from Nick[master]
clearly they are corrupted. This is usually used to check the freshness of eggs.

Answer from Anastasia Selyukova[newbie]
they say if an egg floats with a blunt end, then it is a week old and you can eat it, and if it is sharp, then it is better to throw it away

Answer from Dunno[active]
Floating eggs spoil my appetite and I change them =)

The freshness of eggs for inexperienced housewives is always a mystery. The intrigue lasts until the shell breaks. But seasoned homegrown cooks know that if an egg floats while boiling, something is wrong with it. It is better to cook the dish from other ingredients, and send the spoiled product to the basket.

When cooking, the egg floated: what does it mean

When the eggs float in the water, this is interpreted unambiguously: you have come across a product that is not the first freshness. By moving an item in a saucepan, you can determine how long it has lain on store shelves. To do this, pour cold water into a container, put the eggs before cooking. Wait for the local storm to subside, watch.

Basically, hostesses see the following stages:

• a dietary product that is no more than 8 days old falls to the bottom, does not attempt to rise to the surface;
• an egg that has lain for a week begins to strive upward with a blunt end;
• 2-3 week product hangs upright somewhere in the middle;
• the one that was taken from the chicken more than a month ago pops up completely.

See how the shelf life of a product is visually determined. This is how eggs of various freshness behave in cold water.

These characteristics apply to chicken, quail eggs. The experiment gives reliable results, it is impossible to make a mistake with the definition of freshness. Is that if you start using a boiled egg instead of raw or salt water. Salt increases the density of the liquid, the experiment under such conditions will change.

There is such a situation: you are sure that the instance is fresh, but it still pops up. Scolding the experiment is not worth it, just inspect the egg. There are probably cracks in the shell through which air entered. It is also better not to eat this food - it is not known how the bacteria that penetrated inside affected the quality of the protein and yolk.

Why do eggs float in water

The question can be answered with the same simple observation. As soon as possible, compare 2 products: only from under the bird and lying down. They will have a couple of significant differences that cause the eggs to float to the surface.

What does it mean? Properties change because the shell is not airtight. It has pores that allow oxygen to pass through, microorganisms, so that a potential chick has the opportunity to survive. A certain environment is formed inside the product. If it is not cooled in time, not thermally processed, pathological microorganisms will take over.

Why does it pop up? During storage, eggs lose moisture, available carbon dioxide. The protein becomes more liquid, takes up less space. An air chamber is formed inside - a scarecrow. It causes the laid eggs to strive to the surface of the water.

Why does an egg float in water when boiled?

During heat treatment, even a fresh egg can change position relative to the bottom. This does not mean that the product has suddenly deteriorated. The fright is to blame again - it is the main reason that the boiled egg has surfaced after cooking.

Under the influence of high temperature, the protein and yolk coagulate. Their volume decreases, excess moisture evaporates, the vacant place is occupied by air. The chamber pushes the product out of the water after cooking.

Can you eat eggs that float in water?

If the egg floats in water during cooking, its further fate depends on freshness. A completely floating product should not be eaten. Send it to your shopping cart right away. It is allowed to eat what has lain down for 2-3 weeks, only the egg must be boiled until fully cooked. Poached, scrambled eggs with semi-liquid yolk and protein is better not to do. Health is more expensive.

Eat daily, weekly copies safely. First of all, try to use the latter so that they do not deteriorate. To avoid unpleasant consequences, choose dishes that involve high-quality heat treatment of eggs - salmonella is also found in the freshest.

Consequences if eggs float in water when boiled

If the explanation of the reasons why an egg floats during cooking does not seem convincing and you don’t want to refuse spoiled eggs, pay attention to the consequences of eating them. Yes, the product may have a normal appearance, smell, but the freshness test warns that pathological changes inside are already in full swing. If you eat, you risk earning serious poisoning.

The latter appears 6-8 hours after a meal. Depending on the degree of damage to the body, the symptoms may be different:

• nausea, severe, frequent vomiting;
• abdominal pain - pulling, in the form of colic, spasms;
• lack of appetite;
• diarrhea, in the worst case - with an admixture of mucus, blood;
• general weakness, chills, inability to sleep;
• temperature increase;
• dizziness;
• dehydration;
• limb numbness.

If this occurs, you should immediately seek medical help, otherwise the consequences can be terrible. This is especially true of egg poisoning in children. As a self-medication, it is only useful to induce vomiting, rinse the stomach until an ambulance arrives. If you have a home, it is also allowed to drink a sorbent like activated carbon, enterosgel. Drugs will reduce the number of pathogenic organisms, alleviate suffering.

If you feel sorry for the money spent so much that you are ready to eat a spoiled product, learn how to determine their freshness in the store. To do this, it is useful to remember 5 elementary rules. They will not allow sellers to deceive you or inadvertently choose a stale product.

1. Check retention periods. On the box, each copy should be stamped with production dates, expiration dates.
2. Purchase the product in trusted places where quality certificates are available. Buying eggs from the hands of neighbors, at the farmer's market, from cute grandmothers is a tempting idea. But where is the guarantee that the birds are healthy, and the goods have not been in the owner's refrigerator for a couple of weeks?
3. Use an ovoscope. In large supermarkets, next to the egg shelf, there is a device for determining freshness.
4. Look through the product to the light. If there is no ovoscope, use any other light source. A fresh specimen is completely translucent, has no inclusions. A two-week-old usually shows thin streaks, and a monthly one is distinguished by dark spots.

In this situation, it is possible two options:

1. egg, pre-brewed, turned out to be spoiled - rotten, which is why it pops up.
2. if fresh egg, then in the boiled state its density is less than the density of water, which is why it floats.

• It seems to me that the shell of an egg after cooking ceases to allow air to pass through, while in a fresh one it passes through it. And since the egg has a small cavity filled with air, that's why it pops up. Although I can't say for sure.

  The explanation for this phenomenon is as follows. As a rule, a boiled stale egg (which has lain for a sufficient time in the refrigerator) or a spoiled egg floats to the surface of the water. The fact is that the egg shell has a fine porous structure. The longer the egg lies, the more it is saturated with air, and the protein dries out. As a result, the egg loses its mass and, after boiling, floats to the surface of cold water. In spoiled eggs, rotting processes occur, in which the mass of the egg also decreases and, at the same time, gases are released. For this reason, a spoiled egg also floats to the surface of the water.

  In a spoiled egg, under the shell (in the shell membrane), air and gases accumulate from the vital activity of putrefactive bacteria and microorganisms that have fallen into it. And they are lighter than water, so such an egg floats.

  Boiled egg floats in cold water only if it is quite old or damaged (it may not be damaged, just old). Since the egg of birds breathes, breathing due to the diffusion of gases passing through thousands of microscopic pores in the shell, over time, its internal content dries out, that is, it decreases, while the size of the air chamber and the amount of air in it increase. And since there is more air in the chamber, accordingly, at a certain time, the egg becomes lighter, and therefore floats up.

  A fresh boiled egg will never float! At least, how many of these eggs have been boiled in my life, even a cracked egg only floated if a lot of protein leaked out of it.

  I think an old egg might float. It can be quite edible. It just lost some of its mass during storage. But still, it is better to treat such an egg with caution, if there is at least some hint that it is gone, it is better to throw it away.

  

  A good fresh egg will not float when dipped in water. But an old, stale or missing egg becomes lighter than water and floats to its surface.

  From a long time of storage, the contents of the egg dries out, there is more air in nm and it rises.

  When microbes penetrate inside the egg, fermentation begins there with the release of gases and again the egg becomes lighter.

  So this is a sign, if the egg has surfaced, be wary of it. My wife immediately throws out just in case. She is wary of this. Especially after one of the sons ended up in the infectious diseases hospital after eating eggs.

  Float in the water or spoiled eggs, or old ones. Whether they are fresh or cooked. In the old ones, the protein dries out and there is a lot of air that penetrates through the pores in the egg shell. And in the spoiled ones, rotting and fermentation products occur with the release of gases, such as hydrogen sulfide, which also makes the egg lighter and it rises to the surface.

  Fresh eggs lie at the bottom.

  

  If you put an egg in cold water, which we took from under the chicken, then it will not float.

  But if the Egg is kept, for example, in the refrigerator for 15 days or more, then during this time a large amount of air will accumulate in it.

  After that, the egg will float, because the weight of the egg becomes less due to the air.

  This is how boats that are made of steel work, but due to the fact that there is a large amount of air there, the boats do not sink.

Checking the freshness of eggs at home is easy. To do this, it is enough to pour about ten centimeters into the container of cold water. Dip the eggs in the bowl for a minute.

Bad, spoiled, rotten eggs will immediately float in water. This is due to a violation of the density inside the shells of raw eggs.

This can also occur if storage conditions are violated: non-compliance with the temperature regime, the assumption of a sharp temperature drop.

Eggs that have floated to the surface, but only the very tip is visible from the water, may still be quite suitable for food, but they must be used before all others.

They tend to accumulate air between the shell and the outer shell of the protein. This is a necessary condition for gas exchange.

The layer, like a gateway, saturates the egg with the necessary oxygen for further development, and releases accumulated gases through the shell, including methane. That is why they go out and exhaust such a smell.

Fresh ones stay at the bottom. The amount of oxygen in them is minimal, they were demolished quite recently.

note! A fresh egg always stays at the bottom. The spoiled floats to the surface.

It is almost impossible to check the freshness of raw eggs in the store. It is important to monitor the integrity of the shell.

Bacteria can enter through the cracks and spoil the egg.. After that, it will become unfit for consumption.

How to check a boiled egg for freshness

If the egg is already cooked, then you can check it by cleaning it:

1. Good, young hard to clean. The shell is very tight to the shell, and when peeling, part of the cooked protein leaves together.
2. If it is not the freshest, it will be very easy to clean.. She literally moves away from the protein along with the shell.
3. If the egg is already rotten, then a sharp unpleasant odor will immediately arise when cleaning., which is impossible to confuse.

Important! A fresh boiled egg is difficult to peel. And what has been stored for some time is easy to clean. An egg that has gone bad after cleaning has a sharp unpleasant odor.

Buyers in stores try to take chicken eggs of the first category or selected ones, because they are larger. From the point of view of their usefulness, this is not entirely true.

After all, the largest ones carry old chickens, which are already becoming obsolete. Young growth lays eggs more and more often, but they are noticeably smaller.

Eggs of young chickens are more useful: they have more calcium, magnesium, protein and other useful trace elements.

While large eggs of old laying hens contain more cholesterol, which is the main cause of heart and vascular diseases, and also leads to obesity.

Eggs of small sizes of the second and third categories are much cheaper.

When choosing eggs in a store, pay attention to:

1. The surface of the shell should be smooth and without cracks.
2. Choose the eggs of young chickens - they are more useful.
3. When you get home, use a glass of water to check for freshness.

How to check the freshness of quail and other eggs?

Goose, duck, quail, chicken eggs have a limited shelf life, which largely depends on the temperature regime.

You can also check the freshness of quail eggs with water.. And also, considering the surface of the shell - it should be even, smooth, without flaws and cracks.

The freshness of eggs depends entirely on the storage periods that must be observed. If they have been stored in stores for too long, they are sold at a low price.

They may not be rotten or spoiled, but they already definitely have a completely different structure.

The processes that take place in the egg do not stop, but only slow down when they are placed in the cold.

Waterfowl eggs are rarely used as food. More often they are left for the reproduction of numbers.

The shelf life is determined by the storage conditions of the product. The cooler and more saturated with moisture the environment, the longer the eggs remain fresh.

Be sure to cover the top with a damp cloth or tightly close the lid. Opened eggs dry out quickly. The yolk in this form can be stored in the refrigerator for one to two days. Protein - up to four to five days.

Checking egg quality with an ovoscope

An ovoscope is a device that has been used since ancient times, and is still used today to check the quality of eggs. This simple device is a flashlight with a directional beam of light.

You can check the eggs with an ovoscope at home. It is easy to make at home:

• To do this, you need a regular flashlight or lamp.
• Place the flashlight in a light-tight box so that the light comes from above.
• At the top of the box, you need to make a hole that will be smaller than the size of the egg.
• Put the egg itself on this hole and carefully examine it.

A good quality young egg has a smooth surface and an even color without spots or flaws.. Inside the egg, which has been violated storage conditions, sometimes you can even see how a chicken is born.

This is noticeable by bloody clots inside the shell and specific outlines. A rotten egg, when translucent with an ovoscope, will have an unpleasant cloudy tint.

Important! To keep eggs fresh longer, they do not need to be washed before storage, so as not to break the protective layer of the shell.

On our site you can find a lot of how-tos on the theme of eggs. For example, or. Today we will talk about why rotten eggs tend to float in water.

In general, our distant ancestors began to check this product for freshness in this way. Even then they knew that spoiled eggs do not sink in water. Let's explain this phenomenon in terms of science. So, under the shell is the shell membrane, consisting of two layers. It has the ability to pass air and moisture through itself. As you know, eggs have two edges: one is sharp, the other is blunt. In the latter, this same shell is stratified, resulting in a small air chamber (called puga). The older the eggs, the greater the volume of the scarecrow in it.

It is interesting that although the shell looks completely protected from the influence of the outside world, this is not at all the case. She, for example, quite easily passes microbes through herself. Moreover, this happens almost immediately after the chicken has laid the egg (up to this point, being in the body of the bird, it is a sterile-clean product). When putrefactive processes begin under the shell due to microbes, a gas is released that forms an extremely unpleasant smell of hydrogen sulfide, which results from protein decomposition. Since air and the resulting gases are much lighter than water, a stale egg simply floats up when you put it in a pan.
