What is the white filament of the egg and what is it used for
When you crack an egg and see that white, gelatinous thread attached to the yolk, it’s normal to wonder what it is and if it serves any function. Far from being a defect or an impurity, this filament plays a key role in the nature of the egg and its quality.
What is the name of the white filament of the egg?
That filament is called chalaza. It is a natural structure made up of proteins from the egg itself and appears as two twisted white cords that start from the yolk towards the ends of the egg.
Its presence is completely normal and is indeed a sign of freshness.
What is the chalaza for?
The main function of the chalaza is to keep the yolk centered inside the egg. It acts as a suspension system that prevents the yolk from moving freely and colliding with the shell.
Thanks to the chalaza:
- The yolk remains stable and protected
- The risk of the yolk breaking is reduced
- The embryo (in fertilized eggs) is well positioned for development
In simple terms, it is a natural safety mechanism.
Is it safe to eat the white filament of the egg?
Yes, it is totally safe. The chalaza is composed of proteins similar to those of the egg white, does not alter the taste or texture of food and does not pose any health risk.
Many people remove it just for aesthetic reasons, especially in fine baking, but it is not necessary to do so.
Does the chalaza indicate that the egg is fresh?
Yes. In fresh eggs, the chalaza is usually more visible, firm and defined. As the egg ages, this structure becomes less noticeable and may even disappear.
Therefore, finding a well-marked chalaza is usually a good sign of quality.
Does it have nutritional value?
Although it is a small portion, the chalaza contains:
- Proteins
- Amino acids
- Structural components of the clearing
Its nutritional contribution is not significant in terms of quantity, but it is part of the total protein value of the egg.
Common Myths About White Egg Filament
- “It’s a spoiled egg”: fake
- “It’s an embryo”: false
- “You should not eat”: false
Chalaza does not indicate fertilization or deterioration, and appears in both fertilized and unfertilized eggs.
In summary
The white filament of the egg is not only normal, but also fulfills an essential function. The next time you see it, you know that it is not something strange or dangerous, but further proof of how well designed this natural food is.
