Is it better to refrigerate eggs or keep them at room temperature

Eggs can be stored at room temperature for short-term storage, and refrigeration is recommended for long-term storage. The storage method of eggs is mainly influenced by factors such as storage time, environmental temperature, eggshell integrity, cleanliness, and whether they have been cleaned. When eggs are stored at room temperature, if the ambient temperature is low and well ventilated, they can usually be stored for about a week. The natural state of the pores in the eggshell of eggs stored at room temperature helps maintain the balance of the internal microenvironment of the eggs. But bacterial growth accelerates in high temperature environments, which may cause eggs to spoil. The surface of unwashed eggs has a natural protective film that can reduce the probability of bacterial invasion.

Refrigerated storage can significantly extend the shelf life of eggs, and can be stored for more than a month when the temperature is controlled at around 4 degrees Celsius. Low temperature environment can inhibit the growth of microorganisms such as Salmonella and reduce food safety risks. But if refrigerated eggs are taken out to room temperature, the surface is prone to condensation and water droplets that can damage the protective layer. Eggs that have undergone industrial cleaning must be refrigerated to prevent spoilage due to damage to the protective film.

Regardless of the storage method chosen, it is recommended to place the egg upside down to maintain stability in the chamber. When purchasing, prioritize products with a recent production date and intact eggshells without cracks. Refrigerated eggs should be consumed as soon as possible after removal to avoid repeated temperature changes. Before cooking, the surface of the eggshell should be thoroughly cleaned to ensure sufficient heating and maturation to kill potential pathogenic bacteria.
