Solar drying of Andean tubers reduces moisture and water activity to preserve starch while inhibiting microbes.
Origin: Inca and Quechua (Pre-Columbian (Inca Empire 1438–1533)) — Andes, Peru
See full technique reference →The process relies on low ambient temperatures (30–45 °C) and high solar radiation to drive evaporation, lowering water activity below 0.6 and preventing enzymatic browning. Starch granules remain largely intact, with minimal gelatinization due to the moderate heat, preserving the tuber's textural integrity.
