How long are eggs stored? How can you store eggs for a long time?

In the case of temperature 2-5, eggs can generally be stored for about a month, 15 days at room temperature in winter, and 10 days at room temperature in summer.

Extended shelf life methods.

1. Do not wash the eggs before storing them in the refrigerator, and the eggs with dirt can be wiped with semi-wet hair soaked in warm water first.

2. The big head is up and the small head is down, and it can be kept fresh for a long time when placed vertically in the refrigerator.

3. It is best to evenly coat the surface of the egg with a layer of cooking oil, or wrap it in plastic wrap and put it in the refrigerator, which can prevent the water in the eggshell from evaporating and prevent external bacteria from invading the egg.

Liquid paraffin preservation method Put fresh eggs into liquid paraffin wax and dye them for 1-2 minutes, take them out, dry them for 24 hours and then store them in the jar, check them after 100 days, and the freshness rate can still reach 100%. Bubble alkali preservation method, also known as sodium silicate, glass oil, is a transparent, non-toxic, colorless, odorless viscous gelatinous liquid, which can adhere to the eggshell and block the pores on the eggshell to prevent the discharge of carbon dioxide in the egg, and isolate the invasion of external bacteria, prevent bacteria from multiplying, and has antiseptic ability. The preparation method is:

Choose 45-56 Baumé soak alkali, add water at a ratio of 2:30 and mix evenly, and finally adjust to Baumé. For storage, gently place the eggs in the bubble alkali solution, and the liquid level is 5-10 cm above the egg surface to isolate the air.

Fresh eggs are valid for about 7 months. Carbon dioxide gas preservation method Put fresh eggs in the storage warehouse, seal them around, and fill them with 50%-60% carbon dioxide gas to inhibit the carbon dioxide gas released from the eggs and reduce their respiration to achieve freshness. Beeswax mixture preservation method Mix 10 parts of beeswax, 2 parts of casein, part sugar and 100 parts of water, then put the fresh eggs in, soak them for a few seconds and then take them out to dry, keep them for half a year, and the rate of good eggs is more than 96%.

Grass ash storage and preservation method with a jar, jar or jar as a container, first spread a layer of dry wood ash about 10 cm thick on the bottom layer, and then a layer of eggs and a layer of ash paved, the last layer of ash is a little thicker, placed in a ventilated and dry place, can be preserved for one year. Coating preservation method The lard is burned into mature oil, griseofulvin grams are added per 1 kg, and the fresh eggs are sterilized with 1% peracetic acid, and then the prepared lard is coated on the surface of the eggshell, and then placed in the container after coating. Each kilogram of fresh eggs consumes 7 grams of oil, which can be stored for 5 months without spoiling.

or 1. Don't stick to water. 2. Ensure air circulation (open storage). 3. Room temperature less than 20 degrees can be stored for about 1 week (personal life experience).

Sticky shell eggs have gone bad, and their eggs contain a lot of bacteria. People who eat such eggs can develop diseases such as bacillary dysentery. I hope you don't eat eggs with sticky shells anymore.

Preservation tips——— Eggs bought must be stored in the refrigerator, which everyone knows. But when you put it, you have to put the big head up and the small head down, so I'm afraid you don't know, right? This not only prevents microorganisms from invading the egg yolk, but also helps to ensure the quality of the eggs.

Did you know that an egg is a thing that breathes? The pointed part of the eggshell has small round holes, which are where the air enters and exits (called the air cell) and governs the respiration of the egg. Therefore, if the bulging part is turned downward, the respiration will deteriorate and reduce its freshness.

When stored in the refrigerator, keep the side where the tip protrudes downwards, like a boxed egg. If you put it with fish, leeks, celery and other foods with strong smells, the eggs will absorb these smells, and the smell will not dissipate whether you cook or fry them, so be careful when storing them.

Fresh eggs are refrigerated in the refrigerator for a week to half a month, and if you want to keep them for a long time, they are pickled into salted eggs.

Fresh eggs within a week are the best, there is really no such condition, at most half a month, usually store the big end of the egg, not easy to break.

10 days - 1 month or so. The shelf life of eggs is not the same in different seasons and at different temperatures. In summer, eggs can be kept for about three days at room temperature, and in winter, the temperature is relatively low, and they can be stored for about 15 days at room temperature.

If it is kept in the refrigerator at a temperature of 2-5 ° C, that is, for a long time, it will have a longer shelf life, usually around 40 days.

The value of eggs.

Egg yolk is rich in lecithin, sterols, egg yolk, calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. These ingredients are beneficial to improving the function of the nervous system, so eggs are a good brain food.

Eggs are rich in protein, fat, vitamins and minerals needed by the human body such as iron, calcium, potassium, etc., and the protein is high-quality protein, which has a repair effect on liver tissue damage.

Generally, the shelf life of eggs at room temperature is 15 days. When the temperature is 2-5, the shelf life of eggs is 40-60 days; When the temperature is below 15, the shelf life of eggs is about 30 days. When the summer temperature is above 25, the shelf life of eggs is 7-10 days.

Hard-boiled eggs are recommended to be eaten within 1-2 days, regardless of the environment.

When it comes to the shelf life of eggs, in the United States and other countries, it is usually limited to 45 days, and eggs are required to be stored below 7 degrees Celsius during sterilization, transportation, and sale. The bulk eggs currently sold in domestic supermarkets are generally not marked with the production date and shelf life, and the shelf life of brand boxed eggs is different according to the storage temperature, usually between 30-60 days, and some product packaging suggests that the egg storage temperature should be 2-6 degrees Celsius, and the other are not marked with the storage temperature. Boxed eggs can be stored slightly longer than loose eggs due to waxing and other treatments.

At room temperature, fresh eggs can be stored for about ten days without spoiling.

It is best to eat the eggs you buy within half a month, don't leave them for too long, they will spoil, and the bad eggs will be poisoned after eating.

1. Put it in the refrigerator.

The most appropriate storage temperature for eggs is 5 7, that is, put them in the refrigerator and freezer to store them, if you buy a whole box of eggs, it is best to put them in the refrigerator together with the box, which can ensure the freshness of the eggs to the greatest extent. In the refrigerator, eggs can be stored for up to two months, but within 10 days, the quality of eggs is the best.

2. Do not rinse the eggs to be preserved.

Do not wash bulk eggs before storage, because there are not only pores on the egg shell, but also a thin film, which will destroy the membrane during the cleaning process, and bacteria will easily enter the egg through the pores, accelerating the deterioration of the egg. Branded boxed eggs also do not need to be cleaned, because these eggs have undergone cleaning, disinfection, film and other processes in the factory, which can well ensure the quality of the eggs.

3. The big head of the egg is facing upwards.

Eggs must be placed with their heads facing up, with their heads facing down, stacked upright, not horizontally. Because an egg is a thing that breathes. The large head of the eggshell has some small round holes, which are where the air enters and exits, and is responsible for the "breathing" of the egg.

4. Eggs placed in the refrigerator should not be moved repeatedly.

Eggs stored in the refrigerator should not be moved repeatedly. Especially when the weather is hot, the eggs taken out of the refrigerator should be eaten as soon as possible, and should not be put back in the refrigerator, because when the eggs are cold and hot, small water droplets will be produced on the surface, and bacteria will be attached to the surface of the eggshell.

5. Eggs should not be mixed with volatile substances.

Do not store eggs with food ingredients with strong odors, such as green onions, ginger, garlic, etc. Therefore, the strong smell of such substances such as green onions, ginger, chili peppers, etc., will seep into the eggs through the pores on the eggshell, accelerating the deterioration of the eggs.

Nutrition of eggs.

Each 100 grams of eggs contain grams of protein, mainly ovalbumin and ovoglobulin, which contain 8 kinds of essential amino acids for the human body, and the composition of human protein is very similar, and the absorption rate of egg protein by the human body can be as high as 98%. Each 100 grams of eggs contain 11 15 grams of fat, mainly concentrated in the egg yolk, but also very easy to be digested and absorbed by the human body, the egg yolk is rich in lecithin, sterols, egg lutein and calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins.

An egg contains as many calories as half an apple or half a cup of milk, but it also has 8% of the phosphorus, 4% zinc, 4% iron, and 12.12 percent of the daily needs of the human body6% protein, 6% vitamin D, 3% vitamin E, 6% vitamin A, 2% vitamin B, 5% vitamin B % vitamin B6. These nutrients are essential for the human body, and they play an extremely important role, such as repairing human tissues, forming new tissues, consuming energy, and participating in complex metabolic processes.

It is best to keep eggs in the refrigerator refrigerated, because the constant temperature of about 4° in the refrigerator and the humidity in the refrigerator are especially suitable for storing eggs, and the eggs stored in the refrigerator are as fresh as ever even if they are stored for more than a month. Store the eggs with the tip of the egg pointing downwards so that the large head (air chamber) of the egg can breathe and the stored egg will not be damaged.

When storing eggs in the refrigerator, do not wash the eggs with a damp cloth or water, because there is a film on the surface of the eggshell, which will be destroyed if washed and wiped with a damp cloth, causing bacteria to enter the inside of the egg. If the surface of the egg is dirty, you can simply wipe it with a dry cloth.

It is best to store eggs in an airtight container to avoid smelling with other foods. If you don't have a refrigerator to store eggs, you can bury them with rice bran or sawdust, because these substances have a certain air permeability to avoid mosquito bites when the eggshell is exposed, but the eggs should be eaten as soon as possible.

Eggshells often crack when boiling eggs, and the basic way to avoid breaking the shell is to "boil cold eggs".

The reason for eggshell rupture is due to the fact that the egg white yolk expands in volume when heated, and the expansion rate of liquid is greater than that of solid eggshell, and when the volume of liquid in the contents is greater than the capacity of the eggshell, the eggshell bursts.

However, the protein in the egg will shrink when it solidifies, if the egg is heated quickly, when the outer layer of the egg white is heated and expanded, the inside is still cold, there is no expansion, the total expansion is relatively small, the capacity of the eggshell expansion increased and the capacity of the air chamber in the egg can withstand it, and it will not burst.

When the heating continues, the inner layer begins to expand by heat, the outer layer of egg white has solidified and contracted, the total expansion is relatively small, and the eggshell will not burst. The best way to heat up quickly is to boil the eggs directly in boiling water. Here's how:

After the water boils, put the cold eggs in a small colander and boil them in boiling water for 8 minutes to cook thoroughly (if you want to eat soft-boiled eggs, you can reduce the boiling time), which can not only avoid burning your hands but also prevent them from breaking through the eggshell, and the time is easy to control.

Just keep the water boiling and keep the heat low. Eggs should be cold, eggs just taken out of the refrigerator or in winter is the best, such as eggs are not stored in the refrigerator in summer, soak the eggs in cold water for a while to cool down can also reduce the shell breaking. In winter, eggs and water are relatively cold, even if you use cold water to boil, as long as the water is less and the heating is fast, the eggshell will generally not break.

1. Eggs can be stored for one month if they are refrigerated in the refrigerator. If you store eggs at room temperature in summer, you can store them for about 10 days, and if you store eggs at room temperature in winter, you can store them for about 15 days. Eggs are eggs laid by hens, so eggs are also called chicken eggs and chickens.

2. Eggs are rich in nutrients, such as: protein, fat, amino acids, the shell of eggs is very thin, to handle gently; Eggs are eaten in the following ways: boiled eggs, scrambled eggs with tomatoes, egg custard, and scrambled eggs.

1. The shelf life of eggs is 15 days at room temperature.

2. When the temperature is 2-5, the shelf life of eggs is 40-60 days; When the temperature is below 15, the shelf life of eggs is about 30 days. When the summer temperature is high before 25 days, the shelf life of eggs is 7-10 days. Hard-boiled eggs are recommended to be eaten within 1-2 days, regardless of the environment.

<>1. Pay attention to isolation: fresh eggs are alive, and it needs to breathe through the pores on the eggshell constantly, so it has the function of absorbing odors.

2. Don't store it sealed: Wang Nan, a national senior food inspector, believes that some people think that eggs are dirty and dirty, so they are sealed and isolated in plastic boxes, which is not right. Because the eggs also need to breathe during storage, evaporate water outward, and store them in plastic boxes, the inside of the box is not breathable, and the environment inside is humid, which will dissolve the protective film outside the eggshell and lose its protective effect, accelerating the deterioration of the eggs, so pay attention.

3. Do not wash with water before storage: eggs cannot be washed with water, the protective film outside the eggshell is water-soluble, and washing will destroy the protective film. You can usually buy clean eggs, or buy ordinary chicken wheel mu eggs and store them separately in the refrigerator to avoid cross-contamination.

1. Pay attention to isolation. Fresh eggs are alive, and they need to breathe through the pores on the eggshell constantly, so they have the function of absorbing odors. If it is mixed with foods with bad odors such as garlic and leeks during storage, the eggs will have an odor and affect the eating effect.

Therefore, when storing eggs, care should be taken to isolate them from other foods.

2. Do not store sealed. Some people feel that the eggs are dirty and put them in a plastic box to seal and "isolate", which is not right. Because eggs also need to "breathe" during storage, evaporate water outward, and store them in plastic boxes, the box is not breathable, and the environment inside is humid, which will make the protective film outside the eggshell dissolve and lose its protective effect, accelerate the deterioration of eggs, and pay attention.

3. Do not wash with water before storage. Eggs cannot also be washed with water, the protective film on the outside of the eggshell is water-soluble, and washing with water will destroy the protective film. You can usually buy clean eggs, or buy regular eggs to store separately in the refrigerator to avoid cross-contamination.
