Do eggs need to be stored in the refrigerator during winter

Eggs generally do not need to be stored in the refrigerator in winter, but if the room temperature exceeds 20 degrees Celsius or the environment is humid, it is recommended to refrigerate. The storage method of eggs is mainly affected by factors such as temperature, humidity, and storage time. Eggs can usually be stored for a long time at room temperature in winter, especially in northern regions where indoor temperatures are low. The natural protective film on the surface of eggshells can effectively block bacterial invasion and maintain freshness for about 3 weeks in a low-temperature dry environment. But it is necessary to avoid placing eggs near radiators or in direct sunlight, as temperature fluctuations can accelerate spoilage. If cracks or dirt appear on the surface of the egg, it should be cleaned and refrigerated in a timely manner. In the humid environment of winter in the south or when the temperature in the heating room is high, eggs are prone to moisture, mold, or bacterial growth. If the room temperature continues to exceed 20 degrees Celsius, it will accelerate the evaporation of water inside the egg, expand the air chamber, and affect the quality. In such cases, it is recommended to place the eggs in the refrigerator compartment and control the temperature at around 4 degrees Celsius to extend the shelf life to more than one month. When storing, be sure to place the egg pointed downwards to reduce the contact area between the chamber and the yolk.

Whether refrigerated or not, eggs should be checked for freshness before use. They can be placed in water to test their buoyancy. Avoid contact with strongly scented food during daily storage, and consume as soon as possible after refrigeration to reduce the impact of condensation. Reasonably preserved eggs can maximize the retention of nutrients such as protein and lecithin, and are suitable for various healthy cooking methods such as steaming, frying, and stir frying.
