Eggs – Ropey Strands and Green Rings

Posted by | March 30, 2011

Are the twisted, ropey strands you often see in the egg white safe to eat? Yes, they are. In fact, the more prominent the strands, the fresher the egg. The strands anchor the yolk in the center of the egg. Composed of protein, they are natural part of the egg and safe to eat. It isn’t necessary to remove the strands as they do not interfere with cooking or beating the egg white.

Have you ever eaten a hard boiled egg and found a greenish ring around the yolk? The green ring sometimes occurs in eggs that are overcooked or cooled too slowly after cooking. While the color may look unappealing, the eggs have the same nutritional value and are safe to eat. The greenish ring is caused by sulfur and iron reacting on the surface of the yolk during cooking.
