Question

Percentage of proteins in eggs is

• A. 13 - 14
• B. 14 - 15
• C. 18 - 20
• D. 10 - 12

Hint:

Eggs ≈ 13–14\% protein → a rich, complete protein source.

Answer 1

The Correct Option is B

Protein Content in Eggs

Egg proteins are considered the gold standard for protein quality due to their excellent amino acid profile and high digestibility. The protein content varies slightly between whole eggs, egg whites, and egg yolks.

Options Analysis

• 10-12%: Too low for whole eggs (only applies to certain processed egg products)
• 13-14%: Close to actual value but slightly underestimates
• 14-15%: Accurate range for whole chicken eggs
• 18-20%: Applies only to dried egg whites, not whole eggs

Detailed Composition

Egg Component	Protein Content	Percentage of Whole Egg
Whole Egg	12.5-15%	100%
Egg White	10-11%	58-60%
Egg Yolk	15-16%	30-31%

Key Facts

• Average large egg (50g) contains 6-7g protein
• Egg white is 90% water and 10% protein
• Egg proteins contain all 9 essential amino acids
• Biological Value (BV) of egg protein is 100 (highest possible)

Factors Affecting Protein Content

• Hen's diet and breed
• Egg size (larger eggs have more absolute protein but similar percentages)
• Preparation method (cooking increases digestibility)

Final Answer

The correct percentage of proteins in whole eggs is 14-15%.
