Description
Latin American ceviche is a cold‑cooking technique that uses citrus acid to denature fish proteins and lower pH, thereby inhibiting microbial growth while imparting a firm texture.
Technical
The acidic environment (pH≈2.5–3.0) catalyzes the unfolding of myofibrillar proteins such as myosin and actin, forming opaque protein aggregates that mimic heat‑cooked seafood. Simultaneously, the low pH below 4.6 suppresses the growth of most pathogenic bacteria during the brief marination period. Precise timing and acidity balance safety, texture, and flavor, rooted in coastal culinary traditions.
