The freshness of eggs is a matter of not only taste preferences, but also health safety, because spoiled protein can become a source of serious intestinal infections. Many housewives wonder how many days they can store raw eggs in the refrigerator without fear for their quality, especially if the product was purchased for future use or obtained from poultry. The answer to this question depends on many factors: storage temperature, shell integrity and initial processing of the product.
Under the conditions of modern household appliances, shelf life increases significantly compared to storage at room temperature. The optimal place trays are placed on the middle shelves, where the temperature regime is most stable. Door niches, which are often used for these purposes, are subject to constant temperature changes when opening the refrigerator, which can shorten the life of the product.
In this article we will examine in detail the regulatory deadlines, methods for determining freshness and rules that will help you avoid food poisoning. You will learn how various conditions affect the safety of the white and yolk, and learn how to correctly navigate the labeling.
Standard shelf life of raw eggs in the shell
According to sanitary standards and rules, raw chicken eggs in the shell at temperatures from 0 to +4 degrees Celsius can retain their consumer properties for a long time. For dietary eggs, which are considered the most useful and valuable, the sales period is only 7 days from the date of laying. After this period, they move into the table category.
Table eggs, which we most often see on store shelves, can be stored in the refrigerator much longer. If the temperature is maintained, they can be eaten within 25-30 days from the date of sorting. However, these figures are relevant only for original packaging with an intact shell.
- 🥚 Dietary: up to 7 days (best protein quality).
- 🥚 Canteen: up to 90 days (subject to cold storage).
- 🥚 Washed: up to 12-14 days (the protective layer is broken).
⚠️ Attention: If you purchased eggs on the market from private traders without labeling, consider them table eggs and try to use them within 2-3 weeks, since the laying date in this case unknown.
It is important to understand that the indicated periods are limit values. To prepare dishes that require heat treatment (omelettes, baked goods), you can use a product that has been in the refrigerator for about a month. For soft-boiling or making eggnog, it is better to take eggs that are no more than 10-12 days old.
Factors influencing the safety of the product
How many days raw eggs can be stored in the refrigerator is influenced not only by time, but also by environmental conditions. The main enemy of freshness is temperature fluctuations. Each cycle of cooling and heating (for example, when you open the refrigerator door or leave the product on the table) accelerates the process of spoilage.
The second critical factor is the integrity of cuticles the thin protective film covering the shell. It prevents bacteria from entering and moisture evaporation. If the eggs were washed in production or you washed them at home immediately after purchase, their shelf life is reduced significantly, since the protective barrier is destroyed.
It is also worth considering the proximity of the products. Eggshells are porous and can absorb foreign odors. Storing near strong-smelling foods such as fish, smoked meats or citrus fruits can negatively affect the taste of the protein.
Humidity in the refrigerator also plays a role. Too dry air will cause the contents to dry out, and excess humidity can cause mold to develop on the shell. The optimal humidity for storage is 85-90%.
How to properly arrange eggs in the refrigerator
Many are accustomed to storing eggs in a special plastic container on the refrigerator door, considering this place to be the most convenient. However, from the point of view of maintaining freshness, this is not the best solution. The door is the area with the most unstable temperature, which constantly changes when opening and closing.
For long-term storage, the middle shelves of the refrigerator compartment, in the back, away from the door, are best suited. There the temperature is most stable. It is ideal if you have the opportunity to allocate a separate area or container with a lid for eggs to isolate them from other products.
If you buy eggs in cardboard trays, it is best to store them in this container. Cardboard protects the shell from damage and absorbs excess moisture. Plastic containers are also suitable, but make sure they are clean and dry.
| Storage location | Temperature stability | Recommended period |
|---|---|---|
| Refrigerator door | Low (frequent changes) | up to 15 days |
| Middle shelf (in tray) | High | up to 30 days |
| Fresh zone (0°C) | Maximum | up to 45 days |
| Freezer | Stable low | up to 1 year (without shell) |
Do not put eggs in one big pile without packaging. The pressure from the upper rows can lead to microcracks in the lower ones, which will start the process of deterioration. Place them with the sharp end down - this part contains the air bag, and this position helps the yolk stay in the center.
☑️ Rules for ideal storage
Checking freshness: simple and reliable methods
Even knowing how many days you can store raw eggs in the refrigerator, it is always useful to be able to check their current condition before cooking. The most famous and simplest method is the water test. Pour cold water into a glass and lower the egg into it.
If it lies horizontally on the bottom, the product is absolutely fresh. If the blunt end floats up but the egg is still touching the bottom, it is about 1-2 weeks old and ready for hard boiling or baking. If the egg has completely floated to the surface, it is better to throw it away, since a lot of gas has accumulated inside from the activity of bacteria.
The second method is visual and olfactory. Break the egg into a separate bowl, and not immediately into the general mixture for the dish. A fresh yolk is elastic, tall and holds its shape, and the white is dense and does not spread. An old egg has a flat yolk and easily bursts, and the white is liquid, like water.
- 💧 Test with water: sinks - fresh, floats - spoiled.
- 👃 Smell: a fresh egg does not smell, a spoiled one has the smell of hydrogen sulfide.
- 👁️ Appearance: no pink tint or iridescent film.
⚠️ Attention: Never taste a raw egg to check its freshness! It may be dangerous. Use only visual methods or a test with water.
Also pay attention to the color of the yolk after cooking. If the overcooked yolk has acquired a greenish tint, this is normal (a reaction of iron and sulfur), but if the raw white has a pinkish tint, this is a sign of bacterial development Pseudomonasand the product should not be consumed.
Why do eggs float?
Over time, moisture evaporates through the pores in the shell, and inside air penetrates. The air sac at the blunt end enlarges. When its volume becomes large enough, it pushes the egg to the surface of the water. This is a sure sign that the egg has lost a lot of moisture and could have spoiled.
Features of storing homemade and store-bought eggs
There is a common misconception that homemade (village) eggs last longer than store-bought ones. It really all depends on the processing. Store-bought eggs often undergo mandatory sanitary treatment and sorting, but they can also be washed, which shortens their lifespan.
Home eggs, if they are not washed and collected in a clean nest, have an intact cuticle. Such specimens can be stored in the refrigerator for up to 3 months, maintaining good quality. However, if you brought eggs from the chicken coop and they were stained and then washed with water, they should be eaten within 10-12 days.
Logistics are an important aspect. Store-bought eggs could spend days or even weeks in storage and in transit before ending up in your refrigerator. Domestic eggs come to you immediately after laying (ideally), so their “biological age” is less, even if the calendar shelf life is the same.
Quail eggs have their own rules. Due to the content of lysozyme in their protein (a substance that prevents the growth of bacteria), they are stored longer than chicken ones - up to 60 days in the refrigerator. Duck and goose eggs, on the contrary, are more susceptible to salmonellosis infection and are stored for less time - about 2 weeks.
Is it possible to freeze raw eggs
If you realize that you will not have time to use up the supply of eggs before the expiration date, you can freeze them. However, it is strictly forbidden to do this in a shell - the liquid will expand when freezing, and the shell will burst, dirtying the freezer and creating the risk of fragments getting into the food.
To freeze the eggs, you need to break them, lightly beat the white and yolk together (or separately, if separation is needed) and pour into molds. You can add a pinch of salt or sugar to improve the texture after defrosting. When frozen, the product can be stored for up to 12 months.
This mass should be defrosted slowly, in the refrigerator, and immediately used for heat treatment. Thawed eggs are no longer suitable for salads or fried eggs due to changes in the protein structure, but they are quite suitable for omelettes, pancakes or baked goods.
Frequently asked questions (FAQ)
Can eggs be stored at room temperature?
Yes, if they are unwashed and kept in a cool, dark place, they can be stored for up to 25 days. However, in summer or in hot rooms the period is reduced to 7-10 days. In the refrigerator, the aging process slows down several times.
What to do if there is a crack in the shell?
An egg with a cracked shell cannot be stored. It must be used immediately and must be subjected to thorough heat treatment (hard-boiled or used in baking at high temperatures). If the crack is large and the film is torn, it is better to throw it away.
Why in some countries do eggs lie on shelves and not in the refrigerator?
It depends on the processing system. In the USA and some other countries, eggs may contain disinfectants, which washes off the protective layer, so they required need to be kept refrigerated. In Europe and Russia, unwashed eggs are often sold, which can be stored at room temperature for a limited time, but cold is still preferable.
How can you tell that an egg is boiled if you forget the timer?
A hard-boiled egg can be untwisted on the table. If it spins quickly and for a long time, it is hard inside. A raw or soft-boiled egg will spin sluggishly and quickly stop due to the liquid center, which dampens the inertia.
