What You Need to Know
The process relies on salt diffusion into fish muscle, lowering water activity below 0.6 and inhibiting bacterial growth. Thermal dehydration removes moisture, while surface temperatures above 120 °C trigger Maillard reactions that develop flavor and color. The combined effect yields a protein‑rich, shelf‑stable product.
