Eggs can provide balanced protein, fat, minerals and vitamins, so it was called "the treasure house of human nutrition." However, in the process of egg storage and transportation, many factors such as temperature, humidity, and time will affect some eggs and become unfit for human consumption. In particular 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. Cracked egg 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. 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. Mildew Some eggs are exposed to rain or moisture, will wash off the protective film on the eggshell surface, so that bacteria invade the eggs and mold deterioration, resulting in black spots on the egg shell and mildew, this kind of egg should not buy food. In addition, there are diarrhea yellow eggs, blood tendons eggs, etc. should generally not be purchased for consumption. 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. Shell egg This kind of egg is stored for too long, the yolk film is weak from the tenacity, and the egg yolk is tightly attached to the shell of the eggshell. If it is partially red, it can be eaten, but the egg film is tightly attached to the shell and is dark and dark outside the skin. If you smell something, you should not eat it again.
