What Exactly Is the White Part of an Egg,
That small, unsettling strand has a name: the chalaza. Far from being a defect,
it’s part of the egg’s built‑in engineering, designed to keep the yolk safely suspended
in the center like a passenger strapped into a seatbelt. The more clearly you see it,
the fresher the egg usually is. It isn’t a baby chick, it isn’t a parasite, and it isn’t
something added by factories—it forms naturally inside every normal egg, fertilized or not.
When you cook the egg, the chalaza simply blends into the white and
disappears, the same way it has in every omelet, cake, and scrambled egg
you’ve ever eaten. Our instinct to fear it comes from ancient survival wiring:
we’re programmed to distrust anything unexpected in our food. But in this case,
the “weird” part is actually proof of order, not danger—a quiet reminder that
nature’s design is often far more precise than our first reaction allows.
