What is the temperature for storing eggs

The optimal storage temperature for eggs is 2-5 degrees Celsius. The storage conditions of eggs are mainly affected by factors such as temperature fluctuations, humidity control, placement, storage duration, and shell integrity.

1. Temperature fluctuations

The refrigeration environment should maintain a stable low temperature, as frequent temperature fluctuations can accelerate egg spoilage. The temperature in the refrigerator compartment of a household refrigerator is usually set at around 4 degrees Celsius, which is suitable for storing eggs. Excessive temperature may lead to bacterial growth, while low temperature may cause eggshell freezing and cracking.

2. Humidity Control

Maintaining a relative humidity of 70% -80% can prevent eggs from losing water. Excessive humidity can easily lead to mold, while low humidity can cause the moisture inside the egg to evaporate. Storing eggs in the original cardboard box can help maintain appropriate humidity and avoid absorbing refrigerator odors.

3. Placement Method

Eggs should be stored upright with their pointed ends facing downwards. This placement method can center the egg yolk, reduce the contact area of the gas chamber, and extend the shelf life. Avoid horizontal placement or frequent movement to prevent the egg yolk membrane from rupturing and affecting quality.

4. Storage time

Shell eggs can be stored for 4-5 weeks under refrigeration conditions. Cleaned eggs can damage the surface protective film and should be consumed as soon as possible. Boiled eggs should not be stored in refrigeration for more than one week, as the protein will gradually harden and affect the taste.

5. Shell integrity

Cracked eggs should be consumed immediately and not stored. Damaged eggshells increase the risk of Salmonella contamination. When making a purchase, it is necessary to check whether the eggshells are smooth and crack free. There is no need to clean them before storage. Simply wipe the surface dirt lightly with a damp cloth.

In addition to controlling storage temperature, it is recommended to separate eggs from other fresh foods to avoid cross contamination. Regularly check whether the refrigerator temperature meets the standard, and adjust the temperature appropriately in summer. Before cooking, observe whether the egg mixture is clear and odorless. Discard eggs that are loose or have sticky shells. Reasonable storage can maximize the preservation of the nutritional value of eggs and ensure their safe consumption. For special populations such as pregnant women and infants, it is recommended to choose eggs with higher freshness and shorten the storage time appropriately.
