How long can eggs be stored without spoiling?

The storage of eggs is divided into two types: raw eggs are 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.

Note: Many people like to store eggs after washing, in fact, this will destroy the original outer eggshell membrane of the egg, so that bacteria and microorganisms can enter the egg smoothly, and accelerate the deterioration of the egg.

Hard-boiled eggs can be kept outside for a maximum of 3 days and in the refrigerator for 4-5 days without problems. But no matter how long it is, it will not be very fresh, and it may not be very smelly, but the taste is definitely not fresh, and eating it is not good for people's health.

Eggs can be stored for about 15 days at room temperature in winter, and about 10 days at room temperature in summer. At a temperature of 2-5, eggs can be kept for up to 40 days. It will not deteriorate.

In general, eggs can be kept outdoors for 8-15 days and in the refrigerator for an additional 20-40 days.

The specific time also depends on the cleanliness of the eggs and the storage environment (cleanliness, temperature, humidity, etc.).

You can shake the egg, and if you hear the sound of water in it, or if you break the yolk and egg white, and it flows more easily like water, it is not very fresh.

Eggs can be stored in the refrigerator for more than a month without spoiling.

Egg waffles can be stored in the refrigerator for up to 10 days and unrefrigerated for up to 7 days.

Generally at room temperature, the shelf life of eggs is 15 days indoors in winter and 10 days indoors in summer.

Pick fresh eggs.

Now there are many varieties of eggs, and there is a big gap, if it is not the pursuit of taste, in fact, the nutritional value of various eggs is the same. Choose the eggs that suit you, there is no need to pursue tall eggs, as well as native eggs.

When buying eggs, you should choose eggshells with a rough surface and no luster, such eggs have not been processed, indicating that they are fresh eggs and can be stored for a longer time. Eggs have broken shells, shake and make noises, or fresh eggs that can sink to the bottom when they are put in water, while those that float are stale eggs. 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.

Your question is very general, the shelf life of eggs needs to be determined under certain environmental conditions, such as temperature and humidity ventilation and other conditions, and temperature is the most important condition, the higher the ambient temperature, the shorter the shelf life.

1. Eggs can be stored at room temperature for 10 15 days without being bad, about 10 days in summer and about 15 days in winter. Eggs can be kept in the refrigerator for 1 calendar month. Eggs are stored with the large head with the air chamber facing up at one end to reduce the invasion of bacteria.

Don't wash the eggs when you buy them, there is a layer of hoarfrost on the outer withered shell, which has the effect of sealing the stomata of the eggshell and blocking bacteria.

2. When eggs are stored at room temperature, they should be placed in a cool and ventilated place. Place the egg with the big head up and the small head down, so that the yolk is attached to the bottom of the air chamber after floating, which can prevent bacteria from invading the yolk and prolong the egg preservation time.

3. There is a layer of hoarfrost on the egg shell, which has the effect of sealing the pores of the eggshell, which can not only prevent bacteria from entering the egg, but also prevent the evaporation of water in the egg. Therefore, the eggs cannot be washed after being bought, which will speed up the deterioration of the eggs.

The method of long-term storage of cooked eggs is not bad: ventilation preservation, refrigeration and preservation.

1. Ventilation and preservation.

If the boiled egg can't be eaten temporarily, you can put it in a cool place and don't let it shoot directly. Then spread it flat in a basket so that it can be eaten the next day. If you can't finish it on the same day, there is no problem with putting it on for a day, but we must pay attention to the surrounding environment, do not have exposure to the sun, and do not have some other temperature interference, so that the taste can still be eaten the next day.

2. Refrigerate and keep fresh.

Nowadays, refrigerators have a refrigeration preservation function, so we can put boiled eggs in the refrigerator compartment and grind them for preservation. The usual freshness time is about a week, so if you can't eat the boiled egg, you can keep it fresh in the refrigerator and eat it within a week. On the one hand, it is not spoiled, and on the other hand, it is also for its taste to be better.

How to choose eggs

Generally speaking, the surface of fresh eggs is rougher, and the color is brighter and cleaner; The color of the old eggs is relatively dark yellow, and the shell of the rotten eggs is black, accompanied by oil stains, so it is not recommended to buy such eggs.

Hold the egg in your hand and shake it a few times, listen to it, or feel it with your fingers, if you feel that the egg white and yolk inside are very solid when you shake it, it means that the egg white and yolk are solid, and this egg is fresh; If there is a shaking sound when shaking, it means that the egg has deteriorated; If the egg is completely broken, it will feel like a half-shelled egg when shaken, so shaking it before buying it is an essential way to pick eggs.

The eggs must be placed with the big head facing up, the small head facing down, and stacked upright. If you find chicken manure or feathers on the eggs, be sure not to wash them before storing them.

If it does not deteriorate, it will lose some nutrients and some nutrients. 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. When eggs are past their expiration date, their freshness and nutritional content will be affected.

During the storage process, the eggs also need to "breathe", evaporate the water outward, and store them in a plastic box, 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 the egg, and pay attention.

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.

Eggs can be stored for about 15 days at room temperature in winter, and about 10 days at room temperature in summer. At a temperature of 2 5, eggs can be stored for 40 days, and beyond the expiration date, the freshness and nutrient content of the eggs will be affected. Therefore, don't buy too many eggs at one time, enough to eat for a week.

Precautions for storing eggs:

1. The big head of the egg is upward.

Since the specific gravity of the egg yolk is smaller than that of the egg white, choose to store the egg upright with the big head up and the small head down, and burn it upright, even if the egg white becomes thinner, it will not quickly occur to lean on the yellow and the skin. This not only prevents microorganisms from invading the egg yolk, but also helps to ensure the quality of the eggs.

2. 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 garlic, leeks and other foods with bad odors during storage, the eggs will have a peculiar smell and affect the eating effect.
