Why do eggs go bad?

How to check If the eggs are fresh or not?

In order to distinguish a fresh and old egg, two very famous methods are as follows.

Float test

This is the simplest way to identify fresh eggs. For this test, carefully place an egg in a bowl filled with water. If the egg jumps to the surface and starts to float, it is old. If the egg settles down at the bottom, it is fresh.

The science behind it is after an egg is laid, its temperature drops during which an air cell forms inside of it at the larger end. This space grows larger due to constant evaporation. Therefore an older egg with a larger air pocket floats over water.

Egg candling

Egg candling is performed using a candling lamp to check the stage of chick development inside a fertilized egg. It can also be used to check the freshness of an egg.

A bright light source is used to see through an egg from its broader side. If it looks empty or you feel the egg contents movings inside because of larger air space, the egg is old.

How to store eggs safely?

  • Keep eggs in a cool dark place in the pantry.
  • Always refrigerate washed eggs.
  • Keep track of the expiration dates.

Can eggs be frozen?

Freezing eggs is not recommended. Freezing temperatures considerably damage the quality of an egg such as:

  1. If an egg is frozen intact, the egg and yolk will start to take up more space when they freeze, consequently, breaking the eggshell. 
  2. In addition to this, the yolk inside it will stiffen and look as if it has been boiled. 

The egg white will not be able to serve the purpose of aeration in your baked goods because of textural loss as a result of protein denaturation. So If you do not want to waste your money by freezing eggs then whisk it properly, put the mixture in a freezer bag, and store it for up to 4 months.

If you wish to store your raw egg white and yolk separately, you can save their quality by whisking your egg white or yolk with sugar, salt, or corn syrup depending on their end-use.

How to identify rotten eggs?

  1. Rotten eggs give off a foul smell. 
  2. If the eggshell appears sticky and dusty, discard your egg because it indicates bacterial and fungal contamination respectively.
  3. If there are cracks on the eggshell, the chances of bacterial contamination are high. It is better to toss it in the bin.
