Boxed eggs can be stored slightly longer than loose eggs due to waxing and other treatments.

Should eggs be washed before storage?

Bulk eggs purchased from the free market, if the surface is not particularly dirty, it is better not to wash them, and store them directly.

Hard-boiled eggs are recommended to be eaten within 1-2 days, regardless of the environment.

The time for eggs to spoil is closely related to the temperature and humidity at the time of storage.

Egg Storage Tips:

The air permeability of the egg is generally in the small head part, and the small head facing down can effectively block the air hole, so that the gas in the egg will make the yolk unable to get close to the egg shell, so that there will be no phenomenon of scattering yellow and sticking to the shell.

You can use the rice preservation method, which is also the most common method, you only need to put the big head of the egg up, the small head down, and then put it into the rice, which can effectively block the gaps in the egg shell, it is a natural desiccant.

When storing eggs, keep the pointed ends down and the big heads on top. Because the specific gravity of the egg yolk is lighter than that of the egg white, if the egg is placed horizontally, the egg yolk will float and stick to the egg shell, forming a "yolk egg" or "preserved egg". At the same time, keep the tip pointing down, and the egg's air sac can be kept in its original position, otherwise, the egg skin will easily peel off and bacteria can easily invade.
