What Is That White Stuff in Eggs?

Have you ever cracked open a fresh egg and noticed those white, stringy strands attached to the yolk? It’s easy to wonder: Is it normal? Is it a defect? Should I remove it?

The good news is that those white strands are completely normal, perfectly safe to eat, and actually a sign of a fresh egg.

What Are Those White Strings?

Those strands are called chalazae (pronounced kuh-LAY-zee). They are twisted cords of egg white protein that serve an important purpose.

They Keep the Yolk Centered

The chalazae act like natural anchors, holding the yolk in the center of the egg. This helps protect the yolk from breaking against the shell.

They Indicate Freshness

Prominent chalazae are one of the easiest signs that an egg is fresh. As an egg ages, these strands gradually become thinner and less noticeable.

They Are Not a Baby Chick

A common myth is that the chalazae are the beginning of a chick embryo. This is false. The chalazae are simply part of the egg’s structure. A fertilized egg would show a tiny embryo on the yolk, not twisted white strands.

Are Chalazae Nutritious?

Yes. Chalazae are made primarily of protein, including a protein called mucin. There is no nutritional reason to remove them, and they are perfectly safe to eat. Eggs themselves are an excellent source of complete protein, choline, vitamins, and minerals.
