Abstract

Egg is a popular breakfast food. A whole egg consists primarily of a yolk, a white, and a shell. It also contains a membrane that lines the shell and forms an air cell at the large end. And, two white strands called chalazae that hold the yolk centered. The structural components of the egg include: The shell and shell membranes (10 percent), The albumen or white (60 percent), and The chalazae; and the yolk (30 percent).
