Storing eggs in the refrigerator door spoils them very quickly and this is the best and longest lasting way to preserve them.

The need to buy and preserve food - including eggs - is of interest to many people - because according to weather forecasts, from October to December 2024, many storms and tropical depressions will affect our country, concentrated in the Central region and the Southern provinces, and there is a high risk of heavy rain and floods in the Central region in October and November, and rivers in the North may experience floods in October...

Cold air is likely to be active from November to December 2024, in which severe cold in the North is likely to appear from the second half of December.

With the forecast of dangerous weather, many people are preparing to buy food in advance - and eggs are easy to eat, can be used in many dishes, and have shells that can be kept for a long time, so they are often chosen.

According to nutritionists, eggs contain many nutrients, can be prepared in many attractive dishes and do not take much time. According to scientists, eggs are rich in nutrients such as protein, healthy fats, calories, folate, vitamins A, K, Omega3, B2, B5, B6, B12, D, phosphorus, selenium, calcium, zinc... help nourish the eyes, reduce the risk of macular degeneration, cataracts, and contribute to preventing eye diseases.

The nutrients from eggs also provide vitamin D, which helps the body increase its ability to absorb calcium, prevent osteoporosis, and strengthen hair and nails. The amino acids and other minerals in eggs also help nourish the brain and nerves, reduce the risk of biochemical imbalances in the body, cardiovascular diseases, and weight loss (because eating eggs makes you feel full longer).

How to store eggs in the refrigerator

Most housewives store eggs in trays inside the refrigerator door. However, according to Dr. Tran Hoang Hai, storing eggs in trays attached to the refrigerator door unintentionally creates favorable conditions for salmonella enteritidi bacteria - which causes stomach diseases (found in egg yolks) to develop. The refrigerator door is often opened, causing the temperature of the eggs to change, losing their freshness.

In addition, leaving eggs in a tray attached to the refrigerator door at low temperatures also reduces the activity of enzymes in the eggs - meaning the lower the temperature, the lower the nutritional value of the eggs.

Furthermore, eggs taken out of the refrigerator into a normal environment will have condensation on the surface of the eggshell. These tiny water droplets are a good hiding place for bacteria, causing them to follow these water droplets into the eggshell, causing the egg to spoil quickly and lose its freshness.

Other information also says that the refrigerator door is not suitable for storing eggs, because every time the refrigerator door is opened and closed, the temperature will change. Therefore, eggs and foods stored in the refrigerator door are more likely to spoil than in the refrigerator compartment. Therefore, place the eggs on a tray and push them deep into the refrigerator compartment for better preservation.

According to Dr. Tran Hoang Hai, if properly stored in the refrigerator, eggs can stay fresh for 5-6 weeks. However, nutritionists recommend storing eggs for a maximum of 30 days in a cold environment (if you buy eggs from the market, they can only be stored for about 3 weeks from the time of purchase). But note:

- Clean eggs before storing them in the refrigerator to remove dirt and bacteria on the eggshells that can affect other foods (if you buy eggs at the supermarket, you can skip this step).

- Place the eggs in a box (paper box, plastic box, or special tray) and place deep inside the refrigerator. Do not place the eggs in the tray on the refrigerator door. This will limit the loss of water from the eggs.

- Be sure to place the small end of the egg down and the large end up - this will prevent the yolk from sticking to the inner slimy shell to keep it fresh longer. Store eggs at 25 - 32 degrees Celsius to keep them fresh for about 1 month.

- Eggs taken out of the refrigerator should be processed within 2 hours. If left out longer, bacteria may accumulate.

Folk ways to preserve eggs

According to Ms. Nguyen Thi Van (an egg trader in Bac Ninh), if eggs are kept at dry room temperature, away from direct sunlight, they can be preserved for 7-10 days. However, there are many ways to preserve eggs in folk medicine as follows:

Lime water preserves eggs

Mix lime water with a concentration of 2 - 3%. Clean the eggs, place them in a jar, and pour in lime water so that the water level is 20 - 25 cm higher than the eggs. Place the jar in a cool place, away from sunlight, to keep the eggs fresh for 2 - 3 months.

Salt preserves fresh eggs

Spread a layer of salt at the bottom of the styrofoam box, place the eggs on top and sprinkle salt to cover the eggs. Continue to arrange the eggs and cover with salt until all are gone. Place the box of eggs in a cool place and they can be stored for a whole year.

Beans preserve eggs

Use beans (black beans, green beans, red beans, soybeans...) sprinkled into the styrofoam box with eggs, one layer of beans and one layer of eggs and cover the beans. Then store the styrofoam box containing the eggs in a cool place and you will have fresh eggs for a month without the need for a refrigerator.

Preserve eggs with rice husks and sawdust

Use a foam box to pour each layer of rice husk/sawdust into it, then arrange the eggs on top until they are all gone. Finally, cover the surface with rice husk/sawdust, then close the lid and place the box in a cool place.

Nowadays, aluminum foil helps preserve eggs longer. Photo from the internet.

Nowadays there are several ways to preserve eggs using aluminum foil and cooking oil as follows:

Aluminum foil to preserve eggs

Clean the eggs, wrap each one in aluminum foil and put it in a carton. Then place it in a cool, dry place and it will keep for 1 month.

Brush cooking oil on the egg

Clean the eggs and brush a thin layer of vegetable oil (sesame oil, coconut oil, soybean oil, etc.) on the eggshell - it can be preserved for 1 month and the quality is still good.

Note that people should only clean the egg shells before storing them. Do not wash eggs with water because this will remove the natural protective layer that prevents bacteria from entering the egg, and also reduce the storage period.
