Eggs account for a large proportion of our daily diet. Many people eat almost one egg each day. The nutritional value of eggs is very high, but health experts remind us that some eggs are inedible, so what kind of eggs? Can't eat it?
1, dead fetus eggs:
Eggs are contaminated with bacteria or parasites during hatching, coupled with poor temperature and humidity conditions, and cause embryos to cease to develop. The nutrients contained in this egg have changed, and if it dies for a long time, the protein will be decomposed and produce a variety of toxic substances, so it is unfit for human consumption.
2, rotten eggs:
As the bacteria invade into the eggs, they multiply and become degraded. The shells are gray and even the shell is broken due to the expansion of the internal hydrogen sulfide gas. The mixture in the eggs is grayish green or dark yellow and has a bad odor. This egg can not be eaten, otherwise it will cause bacterial food poisoning.
3, cracked eggs:
During the transportation, storage, transportation, and packaging of eggs, eggs may cause cracks and cracks due to vibration, extrusion, etc., and are easily invaded by bacteria. If they are left for a long time, they are unfit for human consumption.
4, scattered yellow eggs:
Due to violent oscillations such as transportation, the yolk membrane ruptured, causing mechanical yellow dispersal; or it was stored for a long time and was invaded into the egg body by bacteria or mold through the egg shell pores, and destroyed the protein structure causing yellow discoloration, and the egg liquid was thin and turbid. If the scattered yellow is not serious, no odor, after boiling and other high-temperature treatment can still be edible, but if bacteria reproduce in the egg, the protein has been degeneration, there is no smell can not eat.
