How long do eggs have a shelf life? How long is the shelf life of eggs?

Generally, it can be put for about a month, but the eggs in the period from the summer ambush to the beginning of autumn can not be placed, and can only be put for about 10 or 15 days, so be careful.

With the improvement of the quality of life, people pay more attention to nutrition and health in their diet.

For a long time, people have paid attention to the shelf life of milk, bread and canned food, but the shelf life of small eggs has not been paid attention to.

When buying eggs, you only pay attention to whether there are bad eggs and never ask about their shelf life, in fact, most people can't tell how long the shelf life of eggs is.

According to experts, the same as vegetables, meat.

Eggs also have an expiration date. Experiments show that in the case of temperature 2 5, the shelf life of eggs is 40 days, while in winter it is 15 days at room temperature and 10 days at room temperature in summer. If it is stored for too long, the eggs will deteriorate due to the invasion of bacteria, and the shell will stick to the shell and scatter yellow.

Fortunately, many supermarkets have begun to mark the production date of fresh eggs, and you can easily calculate the expiration date based on the date.

The shelf life of eggs at room temperature is 15 days, in summer the temperature is higher, the shelf life is shortened to 10 days, and in winter or in the refrigerator, the temperature is reduced, in 2 5 times, it can be stored for 40 days; In addition, the eggs in the supermarket have indicated the production date, but the bulk eggs do not indicate that the bulk eggs need to be bought less and eaten as soon as possible to avoid expiration.

The function of the egg shell is mainly manifested in several aspects: the exchange of gas between the embryo and the outside world during the incubation process, as well as the conduction of light, heat, sound, etc.; Prevents excessive evaporation of water inside the egg.

Bears the weight of the parent bird during incubation to prevent mechanical damage and microbial entry; Provides the calcium needed during embryonic development; Due to the shape of the egg shell, the eggs in the nest increase stability and gather in a small space, which is conducive to hatching; The surface of the egg has a good camouflage.

At temperature 2 5, eggs can be stored for 40 days, in winter indoor can be stored for about 15 days, and in summer indoor at room temperature eggs can be stored for about 10 days.

The eggs are large and can only be left for 10 days. Li Wendong, a national senior Chinese cook, said that since the specific gravity of the egg yolk is smaller than that of the egg white, the large head of the egg is chosen to be stored upright with the small head facing down, even if the egg white becomes thin, the phenomenon of leaning on the yellow and skin will not occur soon. This not only prevents microorganisms from invading the egg yolk, but also helps to ensure the quality of the eggs.

Bulk eggs 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, some product packaging suggests that the egg storage temperature should be 2-6 degrees Celsius, and the other is not marked with the storage temperature, boxed eggs can be stored slightly longer than bulk eggs due to waxing and other treatments.

Bulk eggs purchased from the free market, if the surface is not particularly dirty, it is better not to wash them, and store them directly. "There are many pores-like pores on the eggshell, and a very thin film. The cleaning process destroys the membrane, and bacteria can easily enter the egg through the pores, causing the egg to deteriorate.

Generally speaking, the shelf life of eggs is 40 days when stored in an environment of 2 5 years, and only 10 days at room temperature in summer.

However, eggs are often stored in the supermarket for a period of time when they are purchased, so it is recommended to buy eggs in a week's amount. For example, if a family of three eats one per person a day, it is enough to buy about 20 pieces at a time. After buying it and putting it in the refrigerator, it is best to wipe it clean with a dry cloth if there is any stolen goods, and remember not to wash them with water.

The shelf life of eggs at room temperature is 15 days, in summer the temperature is higher, the shelf life is shortened to 10 days, and in winter or in the refrigerator, the temperature is reduced, in 2 5 times, it can be stored for 40 days; In addition, the eggs in the supermarket have indicated the production date, but the bulk eggs do not indicate that the bulk eggs need to be bought less and eaten as soon as possible to avoid expiration.

Eggs have a shelf life just like other foods, and there is a difference between room temperature and low temperature shelf life depending on the storage environment and temperature. Expired eggs are not necessarily spoiled, and the reduction of the nutritional value of eggs is also one of the manifestations of expiration.

Eggs actually have an expiration date.

The general temperature is the temperature inside the refrigerator, and the shelf life is about 40 days, if it is normal room temperature, it can be stored for 15 days in winter, and it can be kept at room temperature for about 10 days at most in summer. An easy way to tell if an egg has gone bad is to smell it, but if it smells rancid, throw it away and don't eat it anymore.

In addition, it is important to note that when storing eggs, you should not put them directly in the refrigerator and separate them from other foods. To avoid contamination of the food by bacteria on the surface of the eggshell, it is best to put the eggs in a separate box and then store them in the refrigerator. When buying eggs, be sure not to buy too much, so as not to eat them after the expiration date and waste them.

But it also has an expiration date, so don't buy a lot at once and it will affect your entire digestive tract.

The shelf life of eggs is determined by the temperature and climate, and if the weather is hot, the shelf life of eggs should be a little shorter.

Generally, at room temperature, raw eggs can be stored for about 1 month, 15 days at room temperature in winter, and 10 days at room temperature in summer.

How long do eggs last in the refrigerator:

1. When the refrigerator temperature is 2-5, eggs can generally be stored for about a month.

2. The egg refrigerator can't be eaten for 3 months, it has been broken, although the surface looks no different, but the egg yolk inside has stink. I have such an experience before I put the bought back in the refrigerator, I haven't managed it, and after a month, the eggs are a little bad and I can't eat them, so it's better to eat the eggs I bought back as soon as possible.

3. You can't eat eggs after five months, because the mucin in the egg white will slowly thin under the action of protease after a long time, and the egg yolk will not be fixed. There are already bacteria that have invaded and cannot be eaten.
