SHELL

Bumpy and grainy in textureColor depends on the breed of henAlso known as the bloom or cuticleSemipermeable membrane:

Air & moisture can pass through the egg shell

This allow for the egg to cook when making a hard boiled egg(s)

INNER & OUTER MEMBRANE

Found between the shell and albumen Transparent Contains a source of protein called

keratin This protein is often found in human hair

Both membranes are very strong Serve as a defense against bacteria

AIR CELL

Determines the grade of the egg The egg is held up to a light The size is measured and given a grade The smaller the air cell, the better

Forms when the egg cools & contracts when the hen is laying the egg

Found between the outer and inner membranes

Grows larger with age

ALBUMEN

Comes from the Latin word albus, which means white

4 alternating layers of thin and thick membrane

Contains 40 different proteins Made up of water Also known as egg whites

CHALAZAE

“Ropes” of the egg white. Hold the yolk in place

Attach to the membrane lining Helps keep the yolk from breaking

VITELLINE MEMBRANEClear casing that encloses the

yolkBroken easilyHolds the yolk together Connected to the Chalazae

YOLK Made up of less water than the

albumen More protein and fat than the

albumen Contains several vitamins and

minerals including... Iron Vitamin A Vitamin D Calcium

FUN FACT: The yolk changes color based on what feed the hen ate & the breed of hen
