Sun drying removes moisture from food using ambient solar heat.
Origin: Ancestral Puebloans (pre‑Columbian (c. 1000–1300 CE)) — American Southwest desert
See full technique reference →Solar radiation raises surface temperature, causing water to evaporate and lower water activity below 0.6, which inhibits microbial growth. UV‑A photons can induce DNA damage in surface microbes, providing additional microbial reduction. The low temperatures (<60 °C) limit Maillard reactions, preserving native flavors and colors.
Primary Reaction
evaporation of water (phase change from liquid to vapor)
