What Is the White Strand in Eggs? A Simple Explanation

Food
Why Eggs Need It in the First Place
To understand the chalaza, it helps to understand how an egg is structured.

Inside a raw egg, you have:

The shell (outer protection)Dairy & Eggs

The egg white (albumen)

The yolk (nutrient-rich center)

Membranes and internal structures

The yolk is lighter than you might expect and would naturally drift around inside the egg white if nothing held it in place.

That’s where the chalaza comes in.
