Every week you bring home huge bags of a wide variety of products from the markets and supermarkets. On the one hand, this makes your life much easier, and on the other, 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 here?" We are sure that this problem is familiar to many firsthand. This is especially true for eggs. Although it is a very delicate product, it appearance does not change over time, and therefore "by eye" to determine the freshness of an egg is almost impossible. Of course, it's no secret to anyone that you can break an egg and try to smell freshness, but there are other ways. Here are some ways to check the freshness of your eggs:
Place the eggs in a deep bowl of cold water. If they are left lying on the bottom in a horizontal position, then they are very fresh. Eggs, slightly raised at an obtuse angle upward, are not the first freshness, but they can still be used in cooking hot dishes. Eggs that float to the surface are spoiled and cannot be eaten! We recommend that you get rid of them as soon as possible.
The 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.
Break one of the eggs and notice the condition of the yolk and white. If the yolk is bulging, and the white is viscous and tightly assembled around the yolk, the egg is very fresh. However, if the yolk is flat and the white is runny, this is a sign of a stale egg
Cause: over time, the protein chains (different substances associated with each other) disintegrate, in this regard, in the old egg, the yolk and white are loosely linked together.
If, when shaking, you do not hear extraneous sounds, then you can safely eat the egg - it is fresh. If, at the same time, splashes or squelching are heard, it means that air has entered the egg and expanded the natural air bubble. You can't eat such an egg anymore.
On the packaging of eggs there is always information about the expiration date, which should be paid close attention to. The supplier guarantees that the product will remain fresh if stored properly. Eggs can generally be eaten for some time after the expiration date, but it is strongly recommended that you test them for freshness using the methods described above before doing so.
When eating eggs, special attention must be paid to hygiene. Pay attention to the following guidelines:
Eggs can be stored in the refrigerator for up to 15 days. In the freshness zone
Any housewife would like to buy exclusively fresh eggs, as they have the best taste and culinary properties. At the same time, spoiled eggs can not only interfere with the preparation of the planned dish, but also harm your health. How do you know if an egg is fresh before a spoiled product harms the body? If you don't have an ovoscope in your arsenal, which allows you to illuminate the egg for the smallest defects, you will have to use the means at hand. So how do you check the freshness of eggs in a store?
Another way to test the freshness of chicken eggs is to enlighten them. In a fresh egg, all the insides are clearly visible, while in the old one spots are visible, and a rotten one is not visible at all.
The initial check has paid off and we are now breaking a raw egg. You see, a fresh egg has two levels of protein: thick in the yolk and more watery around the thick. This is a fresh egg. If the protein is completely watery, and there is no faint film around the yolk, this is an old egg.
If you do not have the opportunity to check the freshness of the eggs yourself, you will have to trust the manufacturer. Eggs are divided into two categories: dietary and table eggs. Diet eggs are always marked with a red stamp with the date of manufacture and grade. An egg is considered a dietary one when it was made no more than seven days ago from the date of purchase, then eggs are transferred to the "table" category.
Table eggs have a blue stamp indicating the category, no date of manufacture. The designations “O”, “1”, “2” mean, respectively, “selected” (the largest), “1 category” (slightly less) and “2 categories” (the smallest). Table eggs can be stored for up to 30 days in the refrigerator, and the ideal temperature for eggs is +5 +8 degrees.
The maximum benefits of eggs can be said only if they are fresh. After spending a month in the refrigerator, they lose their nutritional value and become hazardous to health. Once in the body, an expired product causes serious intoxication, which can be fatal. Therefore, it is important to be able to independently determine the degree of freshness of such a product and understand the permissible terms of its suitability. Further in the article, we will tell you in detail what to look for when buying chicken and quail eggs, how long they can be stored and where it is better to do it.
The unique structure of the eggshell allows the inner part to retain its beneficial properties for a long time. But for this, certain storage conditions are important. Otherwise, the inside of the product will begin to dry out, and a foul-smelling chatterbox unsuitable for further use will form.
There are many ways to check the freshness of an egg at home. And for this it is not at all necessary to drag a microscope and the rarest chemical reagents into the kitchen. You can even judge the suitability of these products in the store. Let's go into the details.
Did you know? The People's Republic of China is the largest egg producer in the world today. About 160 million pieces of this product are produced there annually. Many experts attribute this to the fact that chicken first appeared in this country. And it happened somewhere in 1400 BC.
Experts advise against making blind purchases. In their opinion, the visual assessment of the product is important. Therefore, going to the supermarket or the market for eggs, examine them carefully... Recently demolished specimens will be favorably distinguished by a matte shell surface. But those that have already lain for several days will be characterized by a specific glossy shine. But it is not worth focusing only on this verification method. Experts warn that savvy sellers resort to various tricks in order to successfully sell products. One of these is rubbing or washing each piece. So that the purchase does not disappoint with an unpleasant smelling substance, when choosing an egg tray, compare it with the rest of the assortment... Ideally, the whole ten should have shells of the same color and gloss. If you have a diverse set in front of you, most likely the seller mixed in old and fresh eggs. Smell them. A strong unpleasant odor will be heard in heavily expired boxes.
Important! The shell of a fresh egg has a specific smell that is very similar to lime.
Shake up a raw egg as well. If you hear a distinct chatter inside, you should refuse to buy. After all, talkers are not fit for use.
Do not ignore what is stated on the product expiration date... By informing you about this, the manufacturer guarantees the freshness of the product, provided it is stored correctly. Always choose fresh produce and try to use it before the expiration date on the packaging.
Many consumers are not serious about stamps on egg trays and continue to eat expired items. According to experts, in reality, it retains its usefulness for a short time. But before use, its freshness must be double-checked.
This is done in the following ways:
Important! Eggs are a source of salmonellosis, so boil them for at least 5 minutes in boiling water. Keep in mind that Salmonella bacteria lose their viability at temperatures of + 70 ° C.

Break the shell and visually assess the condition of the inside. In recently removed specimens, the protein will be viscous and tightly assembled, and the yolk will be convex. If the testicle has been lying for a long time, then you will see a liquid spreading white and a flat yolk.
A stereotype about the exceptional benefits of chicken and quail eggs has clearly taken root in society. But if the rules for their storage were violated, then there is no need to talk about the nutritional value of this protein food and the saturation of the body with vital substances. In this case, as evidenced by medical statistics, we will talk about poisoning and its consequences.
In addition, improper cooking of eggs, the use of dirty dishes, as well as infected kitchen utensils threatens the development salmonellosis... The bacteria that provoke this disease live in the egg white, yolk and on the shell. Their source is the laying hen. Moreover, even experts will not be able to recognize the infected specimens by external signs. Neither the color of the shell, nor the smell, nor other visual features of the product will give this away.
Did you know? The Chinese dye their eggs red every time a newborn is born in the family. According to folk legends, such a ritual guarantees the baby a long and happy life..
When eating expired or contaminated eggs are dangerous to health: homemade mayonnaise, raw sugar and egg mixture (protein or yolk), as well as all dishes that have not been sufficiently heat-treated. This can be fried eggs, poached eggs, and even traditional fried eggs. Therefore, doctors strongly recommend strictly monitoring the shelf life of such products and cooking them at high temperatures. Signs of egg intoxication become apparent during the first days after eating poor-quality food.
The eater is observed:
Important! To extend the shelf life of eggs at home, grease their shells with pork fat, vegetable oil or petroleum jelly and place in a cold room where the temperature is below +10 ° C. Alternatively, each piece can be wrapped in plain paper and folded with the sharp ends down, covered with burlap..
The manifestation of the listed symptoms largely depends on the victim's immunity. But for any degree of egg poisoning, it is important to protect the body from dehydration.
For this purpose, the following are recommended:
If, after a day, the disease continues to progress, it is necessary, without wasting time, to seek medical help.
How long chicken and quail eggs will be fresh depends largely on their origin and storage conditions:
Did you know? If you hold an ordinary fresh egg for several days in 9% table vinegar, its shell will harden so much that it will not break even from a strong impact on the floor.
For storing such products, most consumers prefer a compartment in the refrigerator door. But experts on this occasion express their indignation, which is associated with a sharp temperature drop. In such conditions, eggs quickly lose their nutritional value and do not represent any gastronomic value.
Experienced housewives advise choosing a place for this kind of product where it is always cold. In no case should you put the tray in the freezer.
It is imperative that each piece be fixed in a stable position with the sharp end down. It is important that the eggs do not touch. It is better to leave them in a special stand or tray, laid out in the cells. Do not forget to close the container, because eggshells are very sensitive to neighboring odors. From the refrigerator, it will absorb everything nearby. Make sure that the temperature in the chamber is at the level +2 ... + 4 ° С... Never wash the shell before storing it. Such manipulations shorten the shelf life.
Sometimes even the most responsible housewife cannot remember how long chicken eggs have been in her refrigerator. A stale product can poison the whole family, so be sure to check the suitability before cooking. The problem of expired products can be not only in spontaneous markets, but also in supermarkets that have a well-known name.
Eggs contain vitamins, minerals, proteins, carbohydrates and fats, amino acids. They take pride of place not only in the adult, but also in the children's diet. In terms of importance, they can be put in second place after milk.
You should not start cooking until you are convinced of the excellent quality of the eggs. Do not forget that they can be demolished several weeks before they hit the shelves. How to determine if an egg is rotten or not?
The protein of this product is completely absorbed by the human body. Better to eat them boiled or fried. But raw can be dangerous if there is an infection in them. They are rich in magnesium, phosphorus, potassium, iron, zinc and other beneficial elements.
They must be eaten by people who rarely go to the sun, because they contain a lot of vitamin D. It is simply indispensable for strengthening bones. Lecithin has a beneficial effect on the liver, brain activity, strengthens the walls of blood vessels. Lutein improves vision, and choline inhibits the development of cancer cells. Folic acid is essential if you are considering becoming a mom.
The shell contains more than 30 trace elements, approximately 2 grams of calcium. It is good to use it in combination with lemon juice. Crush the shells, stir and add to food by teaspoon.
But to get all these benefits, you only need to eat a good fresh quality product.
How to tell if an egg is rotten? Unfortunately, some unscrupulous consumers indicate the expiration date inaccurately. Therefore, the hostess must learn to determine the freshness of an egg "by eye". Then it will be possible to avoid indigestion and other serious diseases that are treated only in a hospital.
Rotten and fresh differ according to the following basic criteria:
The easiest way to recognize a rotten egg is to sniff. Stale has a characteristic odor that is difficult to confuse with any other. Another criterion is the yolk. He should not shake or knock on the walls. If you put it in the light, then the yolk should be clearly visible. On a flat surface, rotten will spin for a long time - this is another method that helps to determine freshness.
Many people know how to identify a rotten egg by placing it in water. This method is based on the laws of physics. Fill a glass with two-thirds of the water and place the egg in it. If it is "not older" 3 days, it will immediately drown in water. Eggs a week old will remain tilted, and rotten eggs will float to the surface.
This is because they are not airtight. Microorganisms can enter the pores that are present on the shell. If putrefactive processes have already begun, then gases will be released, which are raised to the surface.
Of course, these methods cannot always be used in a store. The quality of the product is influenced not only by the weight, but also by the time when it was demolished. Eggs that have not yet turned three days old are assigned the highest grade. A week-old product belongs to the first grade, and three weeks old - to the second.
Its surface should be monochromatic, without cracks and chips. If the shell has a grayish tint and there is no shine, then it is already stale.
There is another test method that can help a shopper in a supermarket determine the freshness of a product. It is necessary to use an ovoscope - a special device for transillumination. When the dark yolk is immediately visible, and it is closer to the shell or sticks to it, darkening is visible, then the product is "old". The spoiled ones are not visible at all. If you do not have a device, you can bring the product to a light source and make sure there are no dark spots under the shell.
When you break the egg, take a close look at the yolk. In fresh produce, it is tight and convex. If it is not the first freshness, then the yolk will be flat, and the white will be watery. Fresh is much more difficult to clean than old.
Fresh they can be stored for quite a long time, but no more than six weeks. They must be placed in the refrigerator separately from other foods.
They absorb foreign odors very quickly. In addition, infections can enter through the pores if infected meat or fish lies nearby. To close the pores, brush the shells with vegetable oil.
They need to be folded with a sharp "nose" down. Then the yolk will not touch the air layer, and "settle" in the center. In this position, it can be stored in the refrigerator for up to five weeks. If the shell is cracked, they should be eaten as soon as possible.
It is not difficult to figure out how to identify a rotten egg when cooking. If it has already completely deteriorated, then the unpleasant smell will be felt immediately, as soon as you pick it up. A rotten egg will look different from normal when boiled. The protein will curl up and you will smell an unpleasant smell as it breaks. Although bacteria will die from high temperatures, you cannot eat it - poisoning is inevitable.
As you can see, every housewife can check the quality of an egg without violating the integrity of its shell. We wish you more fresh, tasty and healthy meals!
Eggs are a product that can be found in any refrigerator. Have you ever had such an experience that you are already boiling eggs and notice that they are spoiled? Or perhaps the packaging does not indicate the date until which the product should be consumed, is it possible to eat them at all or is it better to send them to the trash can? It is not difficult to identify a spoiled egg. In this article, we will tell you how to tell if an egg has gone bad and how to tell if it can be eaten. If eggs lie in your refrigerator for a very long time, you just need to determine if they are fresh in order to exclude deplorable situations.
What does expiry date mean? This is the period of time when the products are the freshest, most delicious, and recommended for cooking. It does not mean at all that after this period has passed, the eggs have deteriorated, they just are inferior in taste to those that are fresher.
The products are indicated by the manufacturer's code (letter and number).
In many countries it is customary to mark the packing time on the eggs themselves. Because they can be sold individually without packaging. The manufacturer is obliged to inform about the period of consumption.
In order for there to be no temperature difference, eggs should be in the coldest part of the refrigerator. The refrigerator door is categorically not suitable for this, because it is here that the temperature regime can fluctuate.
Do not put unwashed eggs on the table in the refrigerator. In many countries, it is accepted that eggs are in kitchen cabinets, they are not put in the refrigerator. Given that the chickens are given all the necessary vaccinations, nothing will happen to the eggs in the cabinets.
If you do not know if the eggs are fresh in your refrigerator, or there are such suspicions that they have been lying for more than 1.5 months, you need to know the signs of rotten eggs, with which you can easily determine whether these eggs can be used in cooking ...
When a boiled egg has a greenish tint, it has been boiled for too long or the concentration of iron in the water is too high. It can be eaten.
If you find bloody spots in the egg, it can also be eaten, it is quite fresh. This does not in any way affect the taste of the egg itself.
Ideally, if the egg is of good quality, it should be in a glass on its side.
If the egg is in an upright position in water, it was packed relatively long ago, but nevertheless it is still suitable for cooking.
An egg that is not fresh enough will not sink. It can still be used in cooking. It needs to be broken into a bowl in order to determine if it is fresh, pay attention to the protein. Eliminate the fact that it is spoiled by smell. An egg not to be used has a pungent smell.
A fresh egg will not show any sounds.
When there are any sounds in an egg, this does not mean that it cannot be eaten, such an egg is quite fresh.
In an egg that is far from the first freshness, the yolk will burst very quickly.
If it floats on a squirrel, this is also an indicator that the egg is old and it is better not to use it in cooking.
Pay attention to the color of the protein itself. A grayish white means the egg is very fresh. A clear protein indicates that the egg is not very fresh, but you can eat it and this will not affect your health in any way.
Be careful:
It is not recommended for children and the elderly to consume eggs with an expired shelf life. You do not need to rely on the fact that eggs can be eaten for some time after the expiration of the period of use, you must definitely know how to check eggs. Be careful not to harm yourself or your loved ones. Always pay attention to the date of manufacture.
