Description
Salt-induced protein denaturation and moisture reduction enhances fish muscle structure.
Technical
NaCl disrupts hydrogen bonds in myofibrillar proteins (especially actin and myosin), causing partial unfolding and aggregation while osmotic pressure draws out free water via the Donnan effect.
Culinary Significance
Creates firmer, more resilient texture in delicate fish for ceviche while concentrating flavor compounds.
