what is the little white thing in an egg？
chalazaeIt's called a chalaza. There are two chalazae in an egg, one that suspends from the top of the shell and one from the bottom. Essentially, these rope-like structures are made up of protein, and they attach to the yolk to protect it from bumping into the sides of the eggshell.2021年5月25日
Subsequently, question is,Is the white part in eggs sperm?
Contrary to popular belief, that white thing floating in raw eggs is not a baby chicken's umbilical cord. It's not chicken sperm or a beginning embryo either. (Fun fact: Most commercially produced chicken eggs are unfertilized.) It's a chalaza—pronounced cuh-LAY-zuh—and it's totally normal and safe to eat.
Correspondingly,Do you remove chalaza from egg?
It made me wonder: Do you really need to remove the chalaza before baking? You don't have to, but you might want to, depending on what you're baking. The chalaza is safe to eat when cooked. In most cases it doesn't break down during the baking process, so yes, you could bite into it.
Then,What is the white string in an egg yolk?
The chalazae are "twisted, cordlike strands of egg white" that anchor the yolk from the top and bottom of the shell membrane, keeping the yolk from getting busted before you crack the egg. In a fresh egg, the chalazae will be especially visible—so don't feel like you need to remove them.
Also asked,Can you eat chalaza?
Is the white stuff in eggs safe to eat? Absolutely. Again, the chalaza is a totally normal part of an egg, but if seeing it unsettles your stomach, don't worry—they tend to disappear after cooking.
Relax. The chalazae's only role is to anchor the egg yolk to the center of the egg. Remember, the eggs we eat are not fertilized, and chickens are not mammals, therefore no umbilical cord, sperm or embryos, my friends. There's even a useful aspect to the chalazae: the larger it is, the fresher the egg.
The chalazae are a pair of spring-like structures that project from the equatorial region of the vitelline membrane into the albumen and are considered to act as balancers, maintaining the yolk in a steady position in the laid egg.

Several worm parasites have been detected within market eggs. The intestinal nematode (Ascaridia galli) has been reported most frequently. Cecal worms (Heterakis spp.), oviduct flukes (Prosthogonimus spp.) and a tapeworm (Cestoda) also have been recovered from eggs.
These two cords, called chalazae, are made of twisted strands of mucin fibers that are a special form of protein. The chalazae hold the yolk in the center of the egg. The yolk is the source of food for the embryo and contains all the fat in the egg. The small white spot on the yolk is call the germinal disc.
Each chalaza contains fibres that appear to be identical with the fibres in the outer layer of the vitelline membrane, but are spirally coiled and embedded in albumen. Typically, they are illustrated as passing to the blunt and pointed ends of the egg (Text-Figure 1).
In the eggs of most birds (not of the reptiles), the chalazae are two spiral bands of tissue that suspend the yolk in the center of the white (the albumen). The function of the chalazae is to hold the yolk in place. In baking, the chalazae are sometimes removed in order to ensure a uniform texture.
