What s the deal with black dots on eggs?

There are spots on the eggs, and it is better not to eat them. Here's why.

Clause. 1. Most of the reasons for egg spots are that the eggs are not fresh, and under normal circumstances, the eggs have a shelf life at a constant temperature.

In about half a month, the quality will definitely decline.

Clause. 2. Egg shells.

Most eggs with spots are infected with bacteria, especially Salmonella.

Clause. Third, it is due to the inflammation of the fallopian tubes in laying hens, so this kind of eggs must not be eaten to avoid unnecessary harm to the body.

After the black dots appear on the eggs, you need to carefully look at the position of the small black dots, whether they are on the yolk or the white. If there are black spots on the yolk, it is mostly because the egg is fertilized after fertilization, which will not pose a threat to health. Also, the area of the black dot is not very large, which is very common.

Once there are black spots on the egg whites, and pieces of eggs appear, everyone should not eat them, and it is likely to be the result of the deterioration of the eggs.

The black spots on the eggs are the plaque produced by the bacteria that have grown after the eggs have been placed in a relatively high temperature environment for a long time, and this plaque is toxic, so eating it is not good for health.

The black spots on the eggs may be caused by the deposition of abnormal substances on the egg shell, which may be caused by the hen's food or its own reasons, or it may be caused by external factors.

Hard-boiled eggs have black spots inside, which may be that raw eggs have been sitting for a long time and are not fresh eggs. It could also be that raw eggs are not stored in the right way. As a result, the substances in the eggs are oxidized, and the shelf life is shortened and deteriorated.

There is a black spot on the egg, perhaps because the egg has been left for too long, or because the egg is moldy.

What's the deal with black dots on eggs? Judging from the **, this black spot is the part of fertilization! This egg is very good, it is a fertilized egg, it is an egg that can hatch chicks! aqui te amo。

If there is such a situation on the egg, it means that the egg has a certain qualitative change.

Don't eat the eggs if they have black spots, I feel that the eggs are not fresh, I hope it will help you, hope.

Eggs have been left for a long time and can be eaten scrambled.

This black dot means that the egg has been fertilized, which means that the egg can really hatch chicks, while eggs without black dots are not.

In addition, black spots are epithelial tissue or other foreign bodies that have fallen off the hen's oviduct and are formed by being wrapped into the egg when egg whites are formed, which is edible. Black spots appear after the egg is eroded by mold, and the judgment of this situation mainly depends on the egg white, if the color of the egg white changes, it cannot be eaten.

Six kinds of eggs are not edible

Cracked eggs: In the process of transportation, storage and packaging, 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.

Sticky shell eggs: This kind of egg is stored for too long, the yolk membrane is weakened from toughness, the yolk is close to the eggshell, if the local red can still be eaten, 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.

Rotten eggs: Because bacteria invade the eggs and multiply in large quantities, resulting in deterioration, the eggshell is dark gray, and even the eggshell is broken due to the expansion of internal hydrogen sulfide gas, and the mixture in the egg is gray-green or dark yellow, with a foul smell, then the egg cannot be eaten, otherwise it will cause bacterial food poisoning.

Loose yellow eggs: due to violent oscillation such as 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, resulting in yellowing and turbidity of the egg liquid. If the yellowing is not serious, there is no peculiar smell, and it can still be eaten after high temperature treatment such as decoction, but if the bacteria multiply in the egg, the protein has been denatured, and it cannot be eaten if it has a foul smell.

Stillborn eggs: Eggs that stop developing due to bacterial or parasite contamination during incubation, as well as poor temperature and humidity conditions, are called stillborn eggs. The nutrients contained in this egg have changed, such as the prolonged death, the protein is broken down to produce a variety of toxic substances, so it is not suitable for consumption.

Moldy eggs: Some eggs are exposed to rain or moisture, which will wash off the protective film on the surface of the eggshell, so that bacteria will invade the inner surface of the egg and become moldy and deteriorate, resulting in black spots on the eggshell and mold, and this kind of egg is not suitable for purchase and consumption.

The above content referencePeople's Daily Online-6 kinds of eggs should never be eaten, beware of being too hurtful.

The black copy dot of the egg is subjected.

Sperm egg, means that the egg is fertilized, but has not yet begun to hatch, if after a period of time, the egg white will appear bloodshot, that is, brown spots, this is a normal phenomenon of fertilized eggs.

There is also a possibility, just like I raise hens freely, because in addition to grains, they shave their own food, and eat what they get, and there is a chicken that eats black food that is not conducive to digestion during the shaving process, such as small scattered rubber bands thrown by others, etc. In this case, it will take on the appearance of raw eggs, but it is also edible, because it returns to sick chickens that do not lay eggs, and chickens that lay eggs do not have the reason to be sick.

That means the egg can hatch chicks.

That is a fertilized egg, which hatches and transforms into a chick.

There are black dots on the yolk of the egg, indicating that the egg is a fertilized egg and can be used to hatch chicks.

If there are no black spots on the egg, it means that the egg is non-fertilized. In terms of nutritional content, these two kinds of eggs are the same, there is no difference, and eating them can help the body replenish nutrients and be beneficial to health.

It is normal to have a black spot on the yolk, but if you find that the egg is full of black spots, it is abnormal, which means that the egg has gone bad and cannot be eaten, and it is easy to have diarrhea and abdominal pain after eating, and you may get food poisoning.

In addition to black spots on the yolk, some people also find that the surface of the egg white will turn black and blue after being boiled for a long time, which is actually normal.

Eggs are rich in a variety of nutrients, and when soaked at high temperatures for a long time, the nutrients in them will change to produce a substance called hydrogen sulfide. This substance can make eggs black, but they can still be eaten and will not cause any health effects.

Although eggs can be eaten even if they are boiled black, it is still recommended to control the time of boiling eggs and not to cook them for too long. If eggs are boiled for too long, some of the nutrients in them will be lost, and the taste will deteriorate. Boil eggs for 8-12 minutes.

Hard-boiled eggs have high nutritional value, and eating 1-2 a day is good for the body, but there are some things that need to be paid attention to when eating hard-boiled eggs.

First of all, the eggs must be fully cooked before eating. Some people like to eat boiled eggs, some people like to eat soft-boiled eggs, and even some people eat raw eggs. Raw and soft-boiled eggs are not healthy to eat.

Only when eggs are fully cooked and cooked thoroughly, the bacteria in them can be killed, there are more bacteria in soft-boiled eggs and raw eggs, and eating soft-boiled eggs and raw eggs often is not good for the stomach. Eating raw eggs often leads to the possibility of food poisoning.

The black spots on the egg shell may also be caused by the deposition of anomalous substances on the egg shell, which may be caused by the hen's food, its own reasons, or external factors.

1. Eggs are in the process of forming eggshells, and the uterine mucosa is abnormally secreted due to inflammation.

2. Abnormal substances are deposited on the egg shell, which will form the egg shell with black spots.

3. Egg waffles.

During the preservation process, it is easy to mold, resulting in black spots on the egg shell.

First of all, most of the reason for egg long spots is that the eggs are not fresh. Usually, the shelf life of eggs at a constant temperature.

For about half a month, if the limit is exceeded, the quality of the eggs will definitely decrease.

Second, most eggs that have spots on their shells are infected with bacteria, especially Salmonella.

Thirdly, due to the oviducts of laying hens.

Inflammation, do not consume this egg to avoid unnecessary harm to the body.

There are two scenarios in which a hard-boiled egg appears with black spots. First, the black spot is the epithelial tissue or other foreign body that falls off the oviduct of the hen, which is formed by being wrapped into the egg when the egg white is formed, which is edible; The second is that the egg is eroded by mold and there are black spots, judging this situation mainly depends on the egg white, if the egg white color changes, it cannot be eaten.

The small black dots on the egg contain these two cases, one is on the yolk and the other is on the egg white, and the reason why there are small black dots on the egg white is because the small black dots on the egg yolk spread to the egg white. These two phenomena will be found after the eggs are cooked, and the eggs in these two cases are not the same, especially when eating, there is a big difference, let's take a look at the expert's explanation of the small black dots.

The first phenomenon, the small black spots on the egg yolk, if you usually eat boiled eggs and have carefully observed friends, you should have found such small black spots, many of which appear on the egg yolk, and some eggs have been rendered around the black spots, and even have a little gray color. Some people will not eat this kind of egg after seeing it, but in fact, this kind of egg with small black spots on the yolk will not affect our normal consumption, nor will it affect the nutritional value of the egg. The explanation given by the experts is that this situation is caused by the fertilization of the eggs, not by their deterioration.

Therefore, you don't have to worry too much, you can eat it with confidence, and there is not much difference between fertilized eggs and ordinary eggs.

The second phenomenon is that there are small black spots on the egg whites, which everyone should pay attention to. The reason why there are small black spots on the egg whites is because some of the eggs have gone bad. There are obvious black spots on the whites of this kind of eggs, and if you encounter this kind of egg, it is best to throw it away and not eat it again.

Because the eggs at this time have no nutritional value of their own, there are also changes in taste, and if you eat them, you will even have stomach trouble. Therefore, for the sake of your own health, everyone should take a closer look when eating eggs.

Why are there small black spots on the yolk of hard-boiled eggs? I regret it before I know, take a look.

Eggs have small black spots, it may be that the shelf life of the eggs is a little problematic, it is recommended not to eat again.
