What You Need to Know
Citric and ascorbic acids from lime juice disrupt hydrogen bonds in conch myofibrillar proteins (particularly actin and myosin), causing tertiary structure unfolding while maintaining peptide bonds. The pH drop to 2.8-3.5 inhibits microbial growth while creating translucent, firm texture.
Creates tender yet chewy texture from tough conch meat while bright acidity balances the mollusk's natural sweetness. Onion thiosulfinates and capsaicin from peppers provide counterpoints.
