There are many reasons for egg yolk scattering: during transportation, due to the violent impact, the egg yolk membrane is broken, leading to yellowing; During the storage of eggs, after protein becomes thinner, water slowly penetrates into the yolk, and when the yolk volume expands to rupture the yolk membrane, yellowing will also occur. After a period of incubation, the yolk of refined eggs will also diverge; Bacteria and molds invade the inside of the egg through the pores of the eggshell, which can also cause the egg to turn yellow.
Many people think that the yolk can't be eaten when it is scattered. It's a pity to throw it away without thinking. In fact, some eggs are not bad and can be eaten. For example, the scattered eggs are shaken violently. This scattered yellow egg liquid is sticky, protein has no denaturation, yellow is easy to separate, and there is no peculiar smell, so it can be eaten.
It can be seen that the only criterion to measure whether yellow eggs can be eaten is smell. If the egg is yellow and smells, of course it can't be eaten; If there is no smell, it can be eaten simply in yellow.
Extended data:
When you find scattered yellow eggs, smell them first. If there is no smell, they can still be eaten after high-temperature cooking. It is recommended to fry, because it can cover up the scattered yellow eggs, and the taste will change more obviously when cooked or steamed.
During the storage of eggs, after the protein is diluted, water slowly penetrates into the yolk, and when the yolk volume expands to rupture the yolk membrane, yellowing will also occur.
After a period of incubation, the yolk of refined eggs will also diverge. Bacteria and molds invade the inside of the egg through the pores of the eggshell, which can also cause the egg to turn yellow. You'd better not eat it.
