Why do egg whites happen?

Answer 1

Egg whites contain more protein (specifically Albumen) than egg yolks do. So as you whisk them, the protein is able to trap the air bubbles within, surrounding each bubble with strands of the protein. This protein is also what makes them so unstable.

Answer 2

The egg white is also known as albumen. Albumen is produced by the hens oviduct. The purpose of the albumen is to protect the embryo (which grows from the yolk) from attack by microorganisms. It also serves as a source of water, protein and minerals for the embryo as it develops.

Answer 4

he physical stress of beating egg white can create a foam. There are two types of physical stress caused by the beating them with a whisk, the first being that the whisk drags the liquid through itself, creating a force that unfolds the protein molecules[citation needed]. This process is called denaturation. The second stress comes from the mixing of air into the whites, which causes the proteins to come out of their natural state. These denatured proteins gather together where the air and water meet and create multiple bonds with the other unraveled proteins, and thus become a foam, holding the incorporated air in place. This is because the proteins consist of amino acids; some are hydrophilic (attracted to water) and some are hydrophobic (repelled by water). This process is called coagulation.[6][7]

When beating egg whites, they are classified in three stages according to the peaks they form when the beater is lifted: soft, firm, and stiff peaks. Overbeaten eggs take on a dry appearance, and will eventually collapse.

Egg whites will not beat up correctly if they are exposed to any form of fat, such as cooking oils or the fats contained in egg yolk.
