How to judge whether the eggs can be eaten after a long time

1. Egg yolk protein mixture:

The yolk is loose, and the egg white and yolk are mixed together and cannot be eaten, which is the most direct way to judge whether the egg has gone bad.

2. Egg yolk is cloudy:

Hold it in a circle with your left hand, place the egg at the end of the circle, and transmit it to the daylight, the fresh egg is reddish and translucent, and the yolk outline is clear; On the other hand, if it is dim, opaque or stained, it means that the egg has deteriorated.

3. Eggs float on the water:

Place the eggs in cold water, if the eggs lie flat in the water, they are fresh; If it is tilted in the water, it has been stored for at least 3 to 5 days; If it stands upright in the water, it may be stored for up to 10 days, and if it floats on the surface, the egg may have gone bad.

4. The eggshell has no pores

A layer of hoarfrost is attached to the shell of fresh eggs, and the eggshells are bright in color and have obvious pores, while on the contrary, they are old eggs.

5. Eggs have the sound of water:

Gently shake the eggs with your hands, the ones that have no sound are fresh eggs, and the ones that have the sound of water are old eggs.

6. Eggshell mold

Some eggs are exposed to rain or moisture, which will wash off the protective film on the surface of the eggshell, so that bacteria invade the inner surface of the egg and become moldy and deteriorate, resulting in black spots and mold on the eggshell.

7. Eggshell cracks:

In the process of transportation, storage and packaging of eggs, due to vibration, extrusion and other reasons, some eggs will cause cracks and cracks, which are easy to be invaded by bacteria, and should not be eaten if they are placed for a long time.

8. Egg yolk sticky shell:

This kind of egg is stored for too long, the yolk membrane is weakened from tough, the yolk is close to the eggshell, if the part is red, you can eat, but the egg membrane is close to the eggshell and does not move, the skin is dark black, and there is a peculiar smell, it is not suitable to eat.

9. Stinkiness: Due to the invasion of bacteria into the eggs and the multiplication of a large number of eggs, the eggshell is dark gray, and even the eggshell is exposed to internal hydrogen sulfide.

If the gas expands and breaks, and the mixture inside the egg is gray-green or dull yellow with a foul smell, the egg should not be eaten, otherwise it will cause bacterial food poisoning.

10. Scattered yellow:

Due to the intense oscillation of transportation, the yolk membrane ruptures, resulting in mechanical yellowing; Or if it is stored for too long, bacteria or mold will invade the egg through the eggshell pores, and the protein structure will be damaged.

Cause yellowing, thin and turbid egg liquid.

How to tell if eggs have gone bad after being left at home for a long time? The working girl slightly used this clever trick to solve it.

How can you tell if you can eat eggs after a long time? The first is to use the method of smelling, if you leave it for a long time, after opening it, you can already smell its smell and smell, then you can't eat it, the second is to leave it for a long time, after opening, its shape is no longer sincere, or there are some other lines marked in it, or there are other colors in it, then you can't eat it.

Eggs have been left for a long time, how to judge whether they can continue to eat, the easiest way is to pick up the eggs, shake them vigorously, if the egg whites and yolks in them are spoiled, there will be centrifugation, which is what we often call wandering.

Hold the egg and shake it, if there is a sound inside, you can feel the liquid shaking inside, this egg is definitely not fresh.

My solution is to hold the egg and shake it, if there is a sound inside, I can feel the liquid shaking inside, the egg is definitely not fresh.

You can use a bowl to catch it first, if you open it and see that it has changed color and taste, it is bad, you can't eat it, don't put it directly into the pot to cook.

If after opening, the yolk has fallen apart, it means that the egg cannot be eaten, and if the yolk is not scattered, it can be eaten.

Generally, if it is yellow, it cannot be eaten, and I judge it from this.

The eggs have been left for a long time, and after you open the eggs, the water is already painful, the yellow has been scattered, and there is a crooked taste, which cannot be eaten.

Shake it, if there is a shaking sound, it proves that it is yellow and cannot be eaten, or open an egg to take a look, and if it smells, it cannot be eaten.

Eggs can be observed from two aspects, the first shell color should be normal, and the second is shaken by hand, and eggs with very shaky can not be eaten.

First, pick it up and shake it, if there is a sound inside, it is a sign that it is empty or bad', and then open if the clear with the yellow cloudy or blanched can not be aqui te amo.

When opened, it turns green or black, and you can't eat it.

See if the color of his egg yolk has changed very deeply, smell whether there is rotten egg yolk, and whether it is scattered.

Eggs, only when opened, will you find out if they are broken.

1. If the egg is stored for too long, the bacteria will invade through the eggshell, resulting in the deterioration of the egg, the phenomenon of sticky shell and yellowing, the proliferation of disease, the deterioration and corruption of the white matter of the egg, and the production of small molecule poisons such as indole and hydrogen sulfide. At the same time, with the extension of storage time, the various nutrients contained in eggs will be destroyed, the nutritional value will be reduced, the taste will become worse, and even become stinky.

2. Spoiled and rotten eggs will cause harm to human health and are inedible, even if they are fried and boiled. The time for eggs to spoil is closely related to the temperature and humidity at the time of storage.

In the north of China, it is stored at room temperature for 30 days and 35 days in summer, and 40 days and 50 days in winter, and generally does not deteriorate.

3. In the south where the temperature is high and humid, it may deteriorate after 25 days and 40 days. When the temperature is higher than 25, the time for eggs to spoil and rot will be significantly shortened.

It depends. Li Shipeng, a public nutritionist, said in his Weibo that eggs can be stored for 40 days at a temperature of 2 5, about 15 days indoors in winter, and about 10 days at room temperature indoors in summer. When eggs are past their expiration date, their freshness and nutritional content will be affected.

Remind everyone: don't buy too many eggs at one time, enough to eat for a week.

Ways to preserve eggs1. The big head of the egg is upward.

Li Wendong, a national senior Chinese cook, said that the egg white of fresh eggs is thick, but with the extension of storage time and the change of external temperature, the mucin contained in the protein under the action of protease will gradually dehydrate and thin, so that the egg white is unbalanced and loses the role of fixing the egg yolk. 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, even if the egg white becomes thin, it will not quickly become yellow and 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 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.

The above content reference: People's Daily Online - 5 major points of attention to storing eggs, 6 kinds of eggs, don't eat them.

It is best not to eat eggs after leaving them for a long time.

The shelf life of eggs is not long, only 15 days at room temperature, if it is a relatively high temperature in summer, then the shelf life of eggs will be shortened by a few days, up to ten days of storage. If the eggs are stored at room temperature for a long time, it is not recommended to eat them, and avoid eating spoiled eggs, which will bring harm to health.

However, if the eggs are refrigerated in the refrigerator, the shelf life will be appropriately extended to 40 days. If it is more than 40 days, it is not recommended to consume it. In fact, spoiled eggs can be seen, first of all, its weight is relatively light, and secondly, there will be mold spots on the eggshell.

When opened, the egg will smell very stinky.

The correct way to store eggs.

1. Store it correctly in the refrigerator, with the big head up and the small head down. In this way, the egg yolk can be floated up and attached to the air chamber, which can not only prevent microorganisms from invading the egg yolk, but also help to ensure the quality of the egg product. The strong smell of volatile substances such as green onions, ginger, and chili peppers will penetrate into the eggs through the pores on the eggshell, accelerating the deterioration of the eggs.

2. Fresh eggs taken out of the refrigerator should be eaten as soon as possible, and should not be stored for a long time or refrigerated again. After the egg is removed, it will sweat at room temperature, and the bacteria and microorganisms in the small water droplets will quickly penetrate into the inner layer of the egg liquid through the eggshell, so the egg can no longer be shelved, so it should be eaten immediately.

Whether the eggs can be eaten after a long time depends on the specific situation, if they are not spoiled, they can be eaten, and if they are spoiled, they cannot be eaten.

If the eggs are stored in the refrigerator, they will be stored for a long time, and if they do not deteriorate, they can still be eaten. If the eggs are left for a long time, the eggs will deteriorate, and they cannot be eaten, and eating spoiled eggs will easily cause discomfort.

Hard-boiled eggs are usually recommended to be eaten within 24 hours, if they are left for a long time, they are inedible, mainly affecting the absorption of nutrients, and may also breed bacteria.

Eggs actually have a shelf life, the general temperature is the temperature in the refrigerator, 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 up to 10 days in summer. The easiest way to tell if an egg has gone bad is to smell it, and if it smells rancid, you need to throw it away and you can'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 wild items. 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.

Eggs generally last for about a month. However, the shelf life of eggs is shorter during the period from the ambush in summer to the beginning of autumn, and can only be stored for about 10 to 15 days, and when the storage time exceeds the period, it cannot be eaten.

How to store eggs in the refrigerator:

Eggs are best stored in the refrigerator, the most appropriate storage temperature is 5 7 usually, if you buy a box of washed eggs, it is best to put the box in the refrigerator, it is better to maintain the freshness of the eggs. When buying loose eggs, then when keeping them in the egg room of the refrigerator, remember to put the eggs with the small head facing down, because the air chamber of the egg is located at the round end of the egg, and putting the big head up can allow the egg to breathe and prolong the life of the egg. Even if the eggs are dirty on the outside, they cannot be washed with water, and the eggs are easy to spoil.

The eggs in the refrigerator can not be taken out and put in, because the eggs taken out of the ice banquet carefully search the box, when they encounter heat, small water droplets will be produced on the surface, and miscellaneous bacteria will also be attached.

As long as the eggs don't stink after opening, they can be eaten. It is not recommended to eat sticky shell and yellowing.

Like vegetables and meat, eggs have an expiration date. Experiments have shown that the shelf life of eggs is 40 days at a temperature of 2 5, compared to 15 days at room temperature in winter and 10 days at room temperature in summer.

Eggs that have exceeded their shelf life will be affected to a certain extent in terms of freshness and nutrient content. 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.
