Eggs are a staple ingredient in many households. However, misconceptions about how to properly handle and store them are common. Here are four tips for correctly storing eggs.
1. Should eggs not be washed with water?
Eggshells have approximately 7,000 to 17,000 tiny pores that allow air and moisture to pass through. The surface of the shell is coated with a natural protective layer called the cuticle, which protects the interior from external bacteria and contaminants. Washing eggs with water removes this protective layer, increasing the risk of bacterial contamination. Therefore, it is best to wash eggs only right before use. After purchasing, wipe them gently with a clean, dry cloth for storage.
2. Storing eggs in the refrigerator door harms freshness
The temperature in the refrigerator door averages 6–9°C (42.8-48.2°F), much higher than the 3–4°C (37.4-39.2-°F) inside the shelves. Opening and closing the door also causes frequent temperature fluctuations, negatively affecting egg quality. Eggs are best stored on a middle shelf inside the refrigerator, with minimal temperature changes. This method helps maintain their freshness for two to three weeks.
3. Eggs should be stored with the pointed end down
When storing eggs, placing them with the pointed end facing down is crucial. The pointed end lacks an air pocket, ensuring the contents remain stable. Conversely, if the rounded end faces down, the air pocket moves upward and comes into contact with the egg’s contents, accelerating spoilage. Properly storing eggs in this orientation can extend their freshness by about 30% in a refrigerated environment below 5°C (41°F).
4. Check the laying date and consume eggs promptly
Packaged eggs usually display the laying date and expiration date. It is ideal to consume eggs within three weeks of the laying date. You can use a simple water test to check their freshness: Place the egg in water. Fresh eggs will sink to the bottom, while older eggs with larger air pockets will float. Eggs that float in water should be discarded immediately.
Small changes in how eggs are handled can significantly impact their freshness. Store eggs in a refrigerated environment below 5°C (41°F), avoid keeping them in the refrigerator door, and consume them promptly by checking the laying date. Additionally, avoid washing eggs with water before storage.
Eggs are a breakfast staple for many. Store them correctly, maintain their freshness, and enjoy them safely.
