How to store boiled eggs?

The science behind boiling eggs?
An egg is a rich source of protein. A large egg has approximately 628g protein, 3.6g of which constitutes the egg white.
The building block of proteins is amino acids which are held together by weak bonds. These covalent bonds are weak enough to be broken by the heat that is provided during boiling.
The heat breaks these weak bonds and stimulates the amino acids to make stronger bonds simultaneously. During this process, water is expelled through the egg resulting in the solidification and denaturation of the protein.
Proteins in an egg pass through the following stages during boiling.
- At 130-140°F, egg proteins start to unfold.
- At 140°F, ovotransferrin turns the egg white into a gelatinous matrix as a result of bonding with itself.
- At 155°F, ovotransferrin is moist but solid.
- At 180°F, ovalbumin makes the egg white firm due to cross bonding.
- Above 180°F, proteins lose water slowly. As a result of dehydration, the egg white develops a dry a rubbery texture and starts to give off a foul Hydrogen sulfide smell.
