How many days can eggs be stored in the refrigerator: complete guide

Organization of proper storage of food is the fundamental basis for the safety and quality of culinary dishes. Chicken eggs they belong to the category of perishable goods that require special attention to temperature conditions. Many housewives are wondering how long this product retains its properties on the shelf of the refrigerator.

The answer depends on many factors: the time of year, the processing method and the original quality of the product. Fresh eggsthat were placed in the refrigerator immediately after purchase are able to remain edible much longer than those that lay for several days at room temperature. It is important to consider that even inside the refrigerator, conditions may vary.

In this article we will examine in detail the regulatory deadlines established by sanitary rules, as well as practical recommendations for extending the freshness of the product. You will learn why eggs should not be washed before storing and how to determine freshness without breaking the shell. This knowledge will help you avoid food poisoning and use resources rationally.

Standard shelf life according to GOST and SanPiN

The Russian Federation has strict standards regulating the circulation of food products. According to the current GOST, the shelf life of dietary eggs is no more than 7 days from the moment of laying. Table eggs can be stored for up to 25 days at temperatures from 0 to 20 degrees Celsius. However, these are the maximum values ​​for warehouses.

When the product is placed in a refrigerator with a temperature range of -2 to +4 degrees Celsius, the time period increases significantly. Dietary product turns into table eggs after 7 days, but continues to remain suitable for consumption. In a refrigerator, table eggs retain their properties for up to 90 days from the moment of sorting.

⚠️ Attention: The indicated periods are only relevant for whole, uncracked eggs that have undergone industrial sorting. If the shell has microcracks or chips, the shelf life is sharply reduced to 1-2 days, as bacteria penetrate inside.

It is important to understand the difference between dietary and table eggs. The first ones are considered the most useful and valuable in the first week and a half. After this period, the white becomes less dense and the yolk becomes more watery, although the product is still safe for heat treatment.

The influence of temperature on preservation

Temperature is the main enemy or friend of any organic product. In a refrigerator, it is important not only the presence of cold, but also the stability of its indicators. Sharp temperature changes contribute to the formation of condensation on the shell, which destroys the natural protective layer and accelerates spoilage.

The optimal place for placing trays is the main chamber, not the door. Door shelves are subject to constant temperature fluctuations when opening the refrigerator. This can lead to the fact that even in a cold unit the eggs will spoil faster than the allotted time.

Let's consider the dependence of the timing on temperature zones:

• 🥚 From 0 to +4°C is the ideal mode that allows you to store eggs for up to 3 months (90 days).
• 🥚 From +4 to +10°C - acceptable mode, shelf life is reduced to 25-30 days.
• 🥚 From +10 to +20°C - room temperature, at which the product is good for no more than 20 days.
• 🥚 Above +20°C - hot conditions, shelf life is only 7-10 days.

Freezing eggs in shell is strictly prohibited. When frozen, the liquid inside expands, causing the shell to rupture and allow bacteria to enter. If you need to preserve a product for a long time, you should break it, mix the white and yolk, add salt or sugar and freeze in an airtight container.

Differences between washed and unwashed eggs

One of the most common questions concerns the need to wash eggs before putting them in the refrigerator. Traces of droppings or feathers often remain on the surface of the shell. Intuitively it seems that they need to be washed off, but from the point of view of biology and chemistry this is a gross mistake.

Nature has provided a special protective film on the surface of the egg - the cuticle. It reliably seals the pores of the shell, preventing pathogens from penetrating inside. Water, especially with detergents, washes off this layer, making the product vulnerable.

Comparative characteristics of shelf life:

If you decide to wash the eggs, use them for food within two weeks. For washing, it is better to use a weak soda solution, but do not scrub with a brush. After washing, the product must be thoroughly dried before storing in the cold.

Is it possible to extend the shelf life of washed eggs?

Yes, if after washing and drying you lubricate the shell with a thin layer of vegetable oil. This will create an artificial barrier that imitates the natural cuticle, and will allow eggs to be stored for up to 3-4 months.

Shelf life of boiled and raw dishes

After heat treatment, the biological structure of the product changes, and its shelf life is recalculated. Boiled eggs in the shell they are stored in the refrigerator significantly less than raw ones. The integrity of the shell plays a lesser role here, since during cooking the protective properties are already partially lost.

Hard-boiled eggs in the shell can be stored for up to 7 days. If the shell is cracked during cooking, the period is reduced to 1-2 days, since water and bacteria have gotten inside. Soft-boiled eggs or “in a bag” have the shortest lifespan - no more than 2 days, since liquid yolk is an ideal medium for the proliferation of microbes.

Peeled boiled eggs are stored for a very short time:

• 🥚 In clean water or container - up to 2-3 days.
• 🥚 Wrapped in cling film - up to 2 days.
• 🥚 In a salad with mayonnaise - no more than 12-18 hours.
• 🥚 In baked goods (pies, pancakes) - up to 2 days.

Protein creams and soufflés containing raw or heat-treated eggs require special care. Their shelf life in the refrigerator should not exceed 24 hours. At room temperature, such desserts spoil in a few hours.

How to check the freshness of an egg at home

Even if the expiration date on the package has not yet expired, the product may deteriorate ahead of time due to violation of transportation conditions. There are several proven ways to determine quality without breaking it down. The most famous method is water test.

Dip the egg into a glass of cold water. If it lies horizontally on the bottom, the product is absolutely fresh. If the blunt end floats up and the sharp end rests on the bottom, the egg is about 1-2 weeks old, it can be consumed after heat treatment. If the entire egg floats to the surface, it is spoiled and dangerous to health.

Other testing methods:

• 🥚 Translucency: bring the egg to a bright light. A fresh egg transmits light evenly, the yolk is barely noticeable. If damaged, dark spots or cloudiness are visible.
• 🥚 Shaking: If you hear gurgling or rolling of the contents when shaking, it means that the white has become too liquid and the air chamber has increased.
• 🥚 Smell: Break the egg onto a separate plate. An unpleasant hydrogen sulfide smell (“rotten eggs”) is a clear sign of spoilage.

⚠️ Attention: Never taste a raw egg if you have doubts about its freshness. Salmonellosis and other intestinal infections can cause serious consequences.

When breaking, pay attention to the state of the protein. In a fresh egg, the white is divided into two fractions: dense (around the yolk) and liquid. If the entire white is uniformly liquid and spreads, and the yolk easily bursts when touched, the product is old.

Markings and designations on eggs

To know exactly the age of the product, You must be able to read the markings on the shell or packaging. In Russia, an alphanumeric designation system has been adopted. First letter indicates the category (shelf life), and the number or the next letter indicates the weight category.

Letter designations of the category:

• 🥚 D —dietary (stored until 7 days).
• 🥚 C — tableware (stored up to 25 days at room temperature, up to 90 in the cold).

Weight categories are indicated by numbers or letters:

• 🥚 B — highest category (75 g or more).
• 🥚 O — selected (65-74.9 g).
• 🥚 1 — first category (55-64.9 g).
• 🥚 2 —second category (45-54.9 g).
• 🥚 3 —third category (35-44.9 g).

Also, the sorting date must be indicated on each egg. It is written in numbers (day and month). For example, the marking C1 05/15 means that this is a table egg of the first category, sorted on May 15th. The expiration date is calculated from this date.

Frequently asked questions about storing eggs

Can eggs be stored outside the refrigerator?

Yes, provided that they are not washed and are in a cool, dark place with good ventilation. At a temperature not exceeding +20°C they can be stored for up to 25 days. However, in the summer without air conditioning, it is better to put them in the cold.

Why can’t you store eggs next to meat or fish?

Egg shells are porous and can absorb foreign odors. Proximity to strong-smelling foods (fish, smoked meats, spices) can change the taste of eggs. In addition, there may be bacteria on the surface of raw meat, which upon contact will penetrate through the pores.

What to do if the eggs are frozen in the refrigerator?

If the eggs are frozen in the shell, you cannot use them raw or cook them whole - the shell will burst and the structure will be damaged. These eggs can be carefully cracked, the contents poured into a bowl, stirred and used for omelettes, pastries or pancakes. The taste will remain virtually unchanged.

How long are ostrich or quail eggs stored?

Quail eggs, due to the content of lysozyme (a natural antiseptic), are stored longer than chicken eggs - up to 60 days in the refrigerator. Guinea fowl and ostrich eggs also have a stronger shell and thicker cuticle, which allows them to remain fresh for up to 2-3 months if stored properly.
