What You Need to Know
The process relies on osmotic dehydration driven by a 5–10 % salt brine, which lowers water activity below 0.6 and inhibits bacterial growth. During 3–5 days of sun‑drying at 30–35 °C and <30 % RH, lipid oxidation generates aldehydes and ketones, while surface proteins undergo Maillard‑type reactions that contribute to flavor and color.
