Do you ever wonder what that weird-looking white string is in raw eggs? Well, the line is called chalaza. The chalaza anchors the yolk from the top and bottom of the shell membrane, keeping the yolk from getting busted before you crack the egg. Usually, if you can see the chalaza, the egg is fresh and healthy. However, if your egg has no chalaza, it could be growing stale or be of lower quality.
Once you cook the egg, the chalaza will disappear without any strategy. Since eggs are a complete protein chock full of health benefits and the egg whites are low in calories and a good source of protein, the chalaza will add to the protein. You should make sure to check for the chalaza every time you crack an egg open to see if your egg is fresh and healthy.
