The white part of the inside of an egg is called the egg white or albumen. The egg white is a clear and viscous substance that surrounds the yolk of an egg. It contains proteins, water, and small amounts of minerals.
The egg white serves as a protective layer for the yolk, providing cushioning and acting as a source of nutrition for the developing embryo. It also helps to provide moisture and structure in cooking and baking, contributing to the texture and consistency of various dishes.
When beaten or whisked, egg whites can become frothy and form stiff peaks, making them useful in recipes for meringues, soufflés, and other desserts. Egg whites are also commonly used in savory dishes for their binding properties or to create light and fluffy textures.
It's worth noting that the egg white is distinct from the egg yolk, which is the yellow or orange part of the egg and contains fats, proteins, and nutrients necessary for the development of a chick if the egg is fertilized.
