What happens to an egg when it’s cooked?

Most interactions with the cooking of eggs involve breaking old bonds in egg proteins through denaturation and forming new ones in their stead. When eggs are cooked, heat denatures the proteins and after the proteins bond with water, the eggs solidify and change color.

Does egg lose protein when you cook it?

Does Cooking an Egg Reduce Its Protein? The way you prepare the egg has no effect on the amount of protein the egg originally contains, but it does have an effect on how much of the protein in the egg you absorb from the egg.

What happens to an egg white when it is fried?

Heat ’em up

Heat energy agitates the egg-white proteins, making them bounce around and hit water molecules and other proteins. These collisions break the weak bonds that held the protein globs curled up, allowing the amino acid chains to partly unwind – a process called ‘denaturing’.

Why do my eggs taste rubbery?

Eggs get rubbery when they are cooked too long at too high temperatures. Think hard boiled. They have a rubbery texture because the protein in the white part of the egg coagulates during cooking. That texture which is expected in the hard boiled egg, is unpleasant in a scrambled egg.
