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
You have learned all the parts of an egg!
