Tag: Eggshell composition

An eggshell, the seemingly simple, hard outer layer, is far more complex than it appears; in fact, a single eggshell contains thousands of tiny pores that allow for gas exchange. While many people assume its hardiness comes from protein, the actual composition is dominated by a different compound, with protein playing a supporting, yet crucial, role.

Did you know a single chicken eggshell consists of about 94-97% calcium carbonate, not pure calcium? This common misconception overlooks the complex mineral structure and organic components that give eggshells their strength and make them a viable source of dietary calcium.

Did you know that up to 95% of an eggshell's weight is composed of calcium carbonate, a completely inorganic mineral compound? This fact confirms that egg shells contain negligible to zero dietary carbs, putting to rest a common nutritional query.
