The heart of the egg yolk is a little hard 15

The inner wall of the fake egg shell generally does not have a protective film.

It may be that the hens that lay eggs are older and have a higher egg laying rate, so there is less pigmentation in the yolk and there may be less pigment in the chicken feed, which will result in the appearance of a white yolk.

That's the egg cell, congratulations you saw it, you're really careful, did you see it, there is a black spot between the egg yolk and the egg white, that is the umbilical cord, it is the egg white that provides nutrition to the egg yolk, hehe, this is the reason why eggs can hatch chicks. Extra points in the game.

This is the fertilized egg of the egg, so there is a white spot in the middle of the yolk, there is no problem with this, you can continue to eat it.

There is also a black spot between the egg yolk and the egg white, that is the umbilical cord, it is the egg white that provides nutrients to the egg yolk, hehe, this is the reason why eggs can hatch chicks. Extra points in the game.

<> hello, for you to find out that the egg yolk in the egg yolk crisp has a hard heart, it may be: the salted egg yolk is not selected well, and the salted egg yolk should be selected for just the right pickling time. When making egg yolk crisp, the treatment of the egg yolk is quite important, too soft to wrap it in it is not good to eat, too hard to do well inside the stupid and hard heart, the taste is even worse.

If the egg yolk is soft and sweet, it means that the marinating time is not enough. Or if it is not pressed tightly enough, such an egg yolk will have a white heart, and the effect of turning sand is not good. If the egg yolk is watery or semi-solid liquid, and it cracks when pressed, it means that the marinating time has been too long.

Pickled and ripe salted duck eggs, the yolk and jujube that come out are hard and can be wrapped directly. <>

Egg yolks. There are two general considerations for stiffness. One is artificial eggs, that is, fake eggs, the yolk is very hard, and it is harmful to the human body after eating.

The second is that the eggs have deteriorated after being left for too long, or the yolk has been oxidized in contact with air for a long time.

As a result, the above situation will occur.

Hard-boiled egg yolks become firm and elastic for many reasons, such as eggs that take a long time, especially at low levels.

Hello, according to your description, I personally feel that it should be a fake egg, because normal eggs are very easy to break if the yolk is boiled, it is recommended to observe whether there are small holes on the tip of the egg when buying egg food in the future, if there is, it may not be a real egg, I hope it can be useful to you!

After a long time, it should be controlled to 10 to 15 minutes.

It's been boiling for too long. It's all hard.
