Do you want to wash the eggs and put them in the refrigerator or not

Eggs are generally recommended to be stored in the refrigerator without washing. Cleaning can damage the natural protective film on the surface of eggshells, increasing the risk of bacterial invasion; Unclean eggs can stay fresh for a longer period of time in low temperature environments. If there is obvious dirt on the surface of the egg, it can be wiped with a dry cloth and refrigerated, but it should be consumed as soon as possible. The egg shell has a natural protective film called the stratum corneum, which can effectively block bacteria from entering the egg through the pores. Cleaning can damage this barrier, especially rinsing with water may cause water molecules to carry bacteria into the eggshell. The refrigeration temperature of the refrigerator is stable at around 4 degrees Celsius, which can inhibit the proliferation of common pathogenic bacteria such as Salmonella. Unclean eggs can usually be stored for 4-5 weeks in this environment. It is important to store eggs inside the refrigerator instead of on the door frame to avoid temperature fluctuations that may affect the freshness.

In some special cases, it may be necessary to clean eggs, such as when the eggshells are contaminated with poultry manure or soil. At this time, warm water at around 40 degrees Celsius should be used for rapid rinsing to avoid negative pressure caused by the contraction of the egg and the inhalation of pollutants. The cleaned eggs should be thoroughly dried before refrigeration, and it is recommended to consume them within a week. Pre cleaned eggs sold commercially undergo professional disinfection treatment and are coated with a food grade mineral oil protective layer, which is fundamentally different from household cleaning.

Eggs should be stored in their original packaging box for daily use, which can avoid cross contamination and maintain humidity. Keeping the tip facing downwards during refrigeration can help center the egg yolk and extend its shelf life. Eggs should not be stored adjacent to strongly scented foods such as onions and garlic to prevent odors from penetrating. Before consumption, a float test can be conducted: fresh eggs sink to the bottom of the water, while spoiled eggs will float up. If long-term storage is required, eggs can be beaten and frozen, but thawed eggs are only suitable for baking or frying.
