Description
Solar drying of Andean tubers reduces moisture and water activity to preserve starch while inhibiting microbes.
Technical
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.
