The inner and outer membranes lying between the eggshell and the egg white contain keratin.
Keratin in Egg Membranes
The tough, protective membranes surrounding the egg white are partially composed of keratin, a strong protein also found in human hair. This protein contributes to the membranes' strength and resilience, offering protection against bacterial invasion.
- Inner and Outer Membranes: These two transparent layers are surprisingly strong due to their keratin content. The reference material explicitly states, "They're made partly of keratin, a protein that's also in human hair."
While eggs are a source of nutrients that support keratin production in the body (like biotin), the keratin itself is primarily located within these inner and outer membranes, not the yolk or white.
