Raw eggs are one of the most versatile and popular food products, which is invariably present in the diet of most families. However, their biological nature implies the presence of certain risks associated with the growth of bacteria, so the question of how long they can remain fresh in the refrigerator is of concern to many housewives.
Proper storage directly affects not only the taste of the future dish, but also the safety of your health, since a spoiled product can cause serious food poisoning. In this article, we will analyze in detail the factors influencing the shelf life and learn how to accurately determine the freshness of the contents of the shell.
Compliance with the temperature regime and the rules of placement in the refrigerator can significantly extend the life of this product, preserving its beneficial properties for several weeks. Let's figure out exactly what conditions are optimal for different types of eggs.
Factors influencing the safety of the product
The main enemy of the freshness of eggs is temperature fluctuations and humidity, so placing them in the refrigerator door, where these parameters constantly change when opened, is not considered the best solution. The ideal place is considered to be the middle shelf or a special compartment in the depths of the refrigeration chamber, where the temperature regime is most stable.
The integrity of protective cuticle the thinnest film that covers the shell immediately after demolition also plays an important role. If you buy washed eggs in a store, this film is removed, which significantly reduces their shelf life compared to unwashed home or farm eggs.
It is also worth considering that the shell has a porous structure and is able to absorb foreign odors, so storage next to strong-smelling foods such as fish or smoked, can negatively affect the taste of the white and yolk.
⚠️ Attention: Never wash eggs before storing for long-term storage! Water washes away the protective layer, opening the pores for the penetration of bacteria, which accelerates the spoilage of the product significantly.
Shelf life depending on temperature
Temperature is a critical parameter that determines the rate of biochemical processes inside the egg. At a standard refrigerator temperature of +2 to +4 degrees Celsius, raw unwashed eggs retain their freshness for as long as possible.
If the temperature in the chamber rises above +10 degrees, for example, when equipment breaks down or frequent power outages, the shelf life is sharply reduced, and the product may become unfit for consumption after 7-10 days.
In the freezer raw eggs in the shell cannot be stored in the chamber, since when freezing, the liquid inside expands and breaks the hard shell, however, the contents can be frozen separately in airtight containers for later use in baking.
Shelf life table for raw eggs
To make it easier for you to navigate the numbers, we have prepared a summary table showing the dependence of shelf life on the conditions and type of processing of the product.
| Product type | Storage conditions | Maximum period |
|---|---|---|
| Homemade (unwashed) | Refrigerator (+2...+4°C) | up to 90 days |
| Store (unwashed) | Refrigerator (+2...+4°C) | up to 25-30 days |
| Washed industrially | Refrigerator (+2...+4°C) | up to 15-20 days |
| At room temperature | Dark place (+18...+20°C) | up to 7-10 days |
As can be seen from the data, the difference in terms can be threefold, so always pay attention to the labeling and method of pre-treatment of the product before purchasing. Dietary eggsmarked letter "D", are stored for only 7 days, after which they are automatically transferred to the canteen category.
How to check the freshness of eggs at home
Even if you follow all the storage rules, you can accidentally use a product that has begun to deteriorate. There are several proven methods for determining quality that do not require complex equipment.
The easiest way is to lower 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, but the egg still touches the bottom, it is about 1-2 weeks old and needs to be consumed as soon as possible.
The floating of the egg to the surface of the water indicates that a large air chamber has formed inside, and it is strictly forbidden to consume such a product raw, as there is a high risk of salmonellosis.
- 💡 Shake the egg near your ear: if you hear gurgling or rolling liquid, it means that the white has become too liquid and the air sac has increased.
- 💡 Break the egg onto a plate: the fresh product has an elastic and high yolk, and the white is divided into two fractions - dense around the yolk and more liquid around the edges.
- 💡 Smell the contents: even a faint unpleasant hydrogen sulfide smell indicates that rotting processes have begun.
⚠️ Attention: If, when breaking, you smell even a faint smell of sulfur or rottenness, immediately throw away the contents and thoroughly wash the dishes with a disinfectant.
Features of storing different types of eggs
Not all eggs are the same, and their origin dictates different handling rules. Quail eggs, due to their denser shell and specific protein composition, can be stored in the refrigerator for up to 60 days, which is much longer than their chicken counterparts.
Ostrich eggs have an incredibly thick shell and can be stored in a cool place for up to 3 months, but after damage to the shell they must be used within 2-3 days. Turkey eggs are similar in properties to chicken eggs, but due to their more porous shell they require especially careful adherence to the temperature regime.
Why do quail eggs last longer?
The protein of quail eggs contains a special substance - lysozyme, which has a powerful antibacterial effect and prevents the proliferation of harmful microflora inside shells.
When buying eggs from different sources, it is important to take into account that store-bought products are often treated with gas or oil for preservation, while farm products retain natural protection, but require a more careful attitude to temperature.
Checklist for proper storage organization
In order for your supplies to remain fresh for as long as possible, it is recommended to adhere to a certain algorithm of actions when placing food in the refrigerator.
☑️ Rules for storing eggs
Following these simple points will allow you to minimize losses and always have a quality ingredient on hand for preparing your favorite dishes. Remember that stability of conditions is more important than absolute temperature indicators.
Frequently asked questions (FAQ)
Is it possible to freeze raw eggs in their shells?
No, you absolutely cannot freeze eggs in their shells. When frozen, the liquid inside expands, causing the shell to rupture and bacteria to enter. In addition, the structure of the protein changes irreversibly, becoming jelly-like after defrosting.
What to do if one egg in the tray is cracked?
A cracked egg must be used within 24 hours, having previously subjected it to thorough heat treatment (hard-boiled or added to baking dough at high temperature). You cannot store a damaged product for a long time.
Why does the yolk stick to the shell?
This is a sign that the egg has been stored for quite a long time. Over time, the air chamber enlarges and the white becomes more watery, allowing the yolk to move and stick to the inner wall of the shell. It is better to use such eggs for baking, rather than for hard-boiling.
Is it harmful to store eggs next to meat?
Yes, this is undesirable. Raw meat can be a source of bacteria, which, if the seal of the packaging is broken, can spread to the egg shells. It is better to separate these products in the refrigerator.
