What You Need to Know
During sun‑drying, the high temperature (30–35 °C) drives water loss, concentrating the fat (30–35 %) and sugars (4–6 %) and promoting lipid oxidation. Spontaneous lactic acid fermentation lowers the pH to 4.5–5.0, inhibiting spoilage microorganisms and contributing to the characteristic sour flavor.
