Why do eggs smell good?

Eggs have a fishy smell. If they are boiled eggs, it may be because the eggshells were not cleaned before boiling. If the smell is not strong, it is normal and you can eat it without worry. If it has a strong fishy smell, the eggs may have gone bad, but the yolk has not fallen apart, so you can't see it has gone bad with the naked eye.

Spoiled eggs generally have a foul odor, and the yolk will be loose or stick to the eggshell when opened. Do not eat these eggs, even if the odor can be reduced by frying or deep-frying.

Eggs have a shelf life. Do not store them for a long time, otherwise bacteria may invade the eggs through the eggshell and cause the eggs to deteriorate.

Eggs that have been exposed to rain can easily spoil and should be kept separate from other eggs and eaten as soon as possible.

What is the difference between selenium-enriched eggs and ordinary eggs?

Selenium-enriched eggs contain 40-60 times more selenium than ordinary eggs. Selenium-enriched eggs refer to eggs with a selenium content of 0.2-0.5 mg/kg, which is produced by adding sodium selenite compound, selenium-containing yeast and organic selenium to chicken feed. Formulated feed is a high-selenium diet made from natural plant organic selenium, multiple vitamins and Chinese herbal medicines.

Selenium-rich eggs use the healthy chicken body as a conversion factory, allowing the chicken to maintain a dynamic balance of selenium in the body during the egg-laying cycle and continuously produce high-selenium eggs containing selenoprotein.
