A strange "egg in an egg" was found when boiling eggs. The price of one egg is equal to the weight of two eggs!

Everyone has eaten eggs. Many lucky friends have cracked open double-yolk eggs, but have you ever seen a "big egg wrapped in a small egg" like the popular online food "big intestine wrapped in small intestine"?

Some time ago, it was reported online that a woman found that the egg she was boiling was a little different. After cracking the eggshell and opening the egg, she unexpectedly found that there was a complete egg with a shell wrapped in the cooked egg white.

Just today, another netizen cracked open an "egg within an egg", which was truly magical.

This bizarre egg-in-egg shape not only makes people feel novel, but also makes people worry about its safety. Could it be another case of "technology and hard work"?

Don't be nervous yet. I can tell you responsibly that there is nothing wrong with this kind of egg in the egg and you can eat it with confidence. However, I believe everyone is curious about its cause and quality, so let's learn about it together.

How is an egg within an egg formed?

In fact, this strange egg in an egg is not a man-made product of some unscrupulous merchants as some netizens claim. Because wrapping a fake egg with another fake egg will undoubtedly increase the cost and have higher requirements for the production process. Even if it is explained as an extremely small probability accident in the processing process, it is hard to believe that unscrupulous merchants who make fake eggs in order to save money and make huge profits can find a substance that is no different from real egg white and inject it into fake eggs.

Regarding the formation of the strange egg in an egg, the current mainstream view is that this may be because the hen's uterus was stimulated by some external factors when the eggshell was formed, causing the oviduct to move in the opposite direction, causing the egg that was originally ready to be laid to return to the upper part of the oviduct, be wrapped by new egg white, and then return to the uterus to form a new eggshell and be laid by the hen, forming an egg in an egg. This is a rare event, but it is still possible given the huge base of more than one billion laying hens in farms across the country, and it does not mean that there is something wrong with the hen that laid the egg.

Double yolk eggs, like eggs within eggs, are also rare occurrences, but they are generally favored by people and are also attributed with the meaning of good luck.

Double yolk eggs are formed because the two egg cells in the hen's ovary mature at the same time and enter the oviduct, where they are coated with egg white and eventually form an eggshell in the uterus. Because they contain two yolks, double yolk eggs are generally larger and longer.

Experienced vendors can quickly identify double-yolk eggs, and they will specially select them and sell them at a higher price. People are also often willing to pay for such double-yolk eggs that are inherently "lucky". After all, everyone wants to be lucky, and in terms of nutritional value alone, eggs with two yolks are always higher than those with only one (in fact, eating one more egg will have the same effect).

Are there big nutritional differences between eggs of different prices?

A small egg contains more than fifteen nutrients that are essential to the human body. It is rich in protein, not to mention vitamin A, vitamin D and other nutrients, which are especially needed by adolescents in their developmental period.

The price of eggs mainly depends on the scale and cost of raising chickens . Since the farms use feed and are large in scale, the cost is low and the price is relatively lower. Most ordinary eggs on the market are 5 to 6 yuan per catty. Some relatively high-priced rural free-range eggs and firewood eggs are mostly obtained by rural individual business owners using free-range methods, and the scale is generally small. Free-range methods use a combination of feed and grain to feed, and some even use grain completely. Therefore, free-range eggs and firewood eggs mainly promote the concepts of pure natural pollution-free and nutritious to attract customers, and the price is generally between 7 and 20 yuan per catty.

When it comes to ordinary eggs and country eggs, people generally believe that the latter have higher nutritional value than the former, and the breeding methods of individual households selling these country eggs seem to prove this point. However, according to actual measured data, the actual content of major nutrients between the two, such as protein, vitamin A, etc., is not much different, and there are only slight differences in taste and flavor.

How to choose fresh eggs?

There are many ways to select fresh eggs. Here are three more convenient and quick methods, which can be summarized in three words: "look", "touch" and "shake".

First of all , the surface of fresh eggs is smoother and covered with a layer of white film , while the surface of eggs that have been stored for a long time will appear shiny and have some black spots. It is best not to eat eggs at this time.

The second is touch . Fresh eggs feel "pressing" in your hand. Eggs that have been stored for a long time will have their moisture evaporated and become lighter. The surface of inferior eggs will feel astringent.

The last step is to shake it . The egg white protein structure inside a fresh egg is relatively stable, and there is less shaking when shaking . If there is an obvious shaking sensation when shaking, it means that the egg is not fresh and the inside has probably started to rot and stink.

"Egg in egg" is like a "hidden version" in a blind box. Next time you buy eggs, you can pick the big ones. Maybe you will "win the prize". Buy one get one free, what a good deal!
