Mention its nutritive value per 100gm.

Nutritive value in terms of content per egg weighing 60 g

Why egg protein is called the "reference protein”?
• Egg protein contains all the nine essential amino acids (EAA) and in the right proportion.
• NPU of egg protein is 100.
It is rich in which group of vitamins?
Egg is rich in both fat and water-soluble vitamins except vitamin C.
What is the recommended method for consuming eggs? Why?
It is recommended to cook the egg before consumption. This is because of the following reasons:
• Raw egg white is not assimilated in human gut.
• Raw egg contains “avidin” which prevents absorption of biotin by the body. Cooking destroys avidin.
Mention the criteria of a good egg.
• Water density test—fresh egg sinks to the bottom of water and lie on the side, horizontal to the surface of water.
• Lesser fresh eggs sink but stand at an angle to the bottom.
• Old and nonfresh eggs float on water and should be discarded.
This is because as the egg ages, the air sac inside it grows larger, making it lighter.
