Eggs are a very common ingredient, and many people like to eat one egg a day to protect their health. But the editor would like to remind everyone that there are four types of eggs that should not be eaten!
1. Dead-in-shell eggs:
Eggs in which the embryo stops developing due to contamination by bacteria or parasites, combined with poor temperature and humidity conditions, are called dead-in-shell eggs. The nutritional content of this type of egg has changed. If the death occurred a long time ago, the protein will decompose and produce various toxic substances, so it should not be eaten.
2. Rotten eggs:
Due to bacterial invasion and massive reproduction inside the egg, it becomes spoiled. The eggshell turns a dark grayish color, and the internal gas (hydrogen sulfide) can even cause the shell to expand and rupture. The egg's contents will appear gray-green or dark yellow and have a foul odor. This egg cannot be eaten, otherwise it will cause bacterial food poisoning.
3. Cracked eggs:
During transportation, storage, and packaging, eggs can be damaged by vibration and squeezing, causing cracks. This makes it very easy for bacteria to invade. If the egg has been stored for a long time, it should not be eaten.
4. Broken-yolk eggs:
This can be caused by violent shaking during transportation, which ruptures the yolk membrane, leading to mechanical breakage. Alternatively, if stored for too long, bacteria or molds can enter the egg through the pores in the shell, destroying the protein structure and causing the yolk to break. The egg liquid will be thin and cloudy. If the yolk is not seriously broken and there is no odor, it can still be eaten after being cooked at high temperatures, such as frying or boiling. However, if bacteria have multiplied inside the egg, the protein has denatured, and it has a bad smell, it should not be eaten.
Summary: The editor has briefly explained why the four types of eggs mentioned above should not be eaten. I hope that next time we encounter these four types of eggs, everyone will stop using them, otherwise, your health will be at risk.
