How to keep eggs from spoiling

Eggs can be preserved by refrigeration, avoiding cleaning, placing them with blunt ends facing upwards, isolating odors, and regular inspections to extend their shelf life.

1. refrigerated storage

Placing eggs in the refrigerator compartment is the most effective method of storage, as maintaining a temperature of around 4 degrees Celsius can significantly inhibit bacterial growth. It is recommended to use original paper boxes or covered containers when refrigerating to avoid eggs absorbing the odors of other foods in the refrigerator. Eggs taken out of the refrigerator should be used as soon as possible, as repeated alternation of hot and cold can accelerate spoilage.

2. Avoid cleaning

Fresh eggs have a natural protective film on the surface, and washing with water can break this barrier, making it easier for bacteria to invade. If the eggshell is contaminated, it can be gently wiped with a dry cloth. Eggs that require long-term storage can choose to apply food grade mineral oil to the shell, which can seal the pores of the eggshell and delay spoilage.

3. Blunt end facing up

The blunt end of an egg has an air chamber. Placing it facing up can keep the yolk in the center position and prevent the air chamber from being compressed and ruptured. Using specialized egg trays or racks can better secure the position and prevent rolling and collision during transportation or storage. This method is particularly important for eggs that need to be stored for a long time.

4. Isolate odors

Eggshells have breathability and are easy to absorb strong odors such as onions and garlic. When storing, it should be kept away from strongly scented food or isolated in a sealed container. Baking soda or charcoal can be placed in the storage space to absorb odors, but it is important to regularly replace the adsorbent material to maintain its effectiveness.

5. Regular Inspection

Check the storage status at least once a month. Place the eggs in clean water to test their freshness. Sinking eggs are considered fresh, while floating eggs that have spoiled should be discarded. Observe whether there are cracks or mold spots on the eggshell, and pay attention to whether the protein is cloudy and diffused when hatching. The frequency of inspections should be increased in summer or humid environments.

In addition to proper storage methods, it is recommended to purchase eggs reasonably according to household consumption. Ordinary refrigerated eggs are best consumed within 3-5 weeks. Before cooking, eggs can be allowed to warm up at room temperature for 10 minutes, but should not exceed 2 hours. Special attention should be paid to the production date of bulk eggs, and eggs directly supplied by farms need to be strictly stored as they have not been industrialized. If the viscosity of the egg white decreases or the yolk is easily scattered, even if it has not expired, it should be stopped from consumption.
