What You Need to Know
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.
Creates firmer, more resilient texture in delicate fish for ceviche while concentrating flavor compounds.
