There are two lumps in the egg, one is yolk and the other is like fat. I don't know what that is.
Another fat-like lump is the yolk tie of an egg, one at each end of the yolk, which is used to fix the yolk. It is flocculent because protein is concentrated. It is like a rope, which fixes the yolk on the eggshell and keeps it in the center of protein. When it vibrates, it plays a buffering role and protects the yolk from harm.

Basically, all eggs will have this structure. If you can see the yolk ligament in the eggs you buy, it means that the eggs you buy are fresh enough and not a sign of fertilized eggs. Sometimes we will find a small spot on the yolk of an egg, which is a unique structure of fertilized eggs and is called "blastoderm". This kind of egg is safe to eat and will not have adverse effects on the body.

Such eggs can't be eaten

1, rotten egg

Because bacteria invade eggs and multiply, eggshells turn dark gray, and even the eggshells are broken due to the expansion of hydrogen sulfide gas inside. However, the mixture in the egg is grayish green or dark yellow, smelly and inedible, otherwise it will cause bacterial food poisoning.

2. Broken eggs

In the process of transportation, storage, transportation and packaging, some eggs will crack and be easily invaded by bacteria. If they are left for a long time, they should not be eaten.

3, stillbirth eggs

Eggs contaminated by bacteria or parasites during incubation, coupled with poor temperature and humidity conditions, cause embryos to stop developing, which is called dead spawning. The nutrition of this egg has changed. If you die for a long time, protein will decompose and produce a variety of toxic substances, so it is not suitable for eating.
