Controlled-humidity dehydration removes water from foods while maintaining a water activity below 0.6, preserving safety and extending shelf life.
Origin: Mediterranean, Middle Eastern, Asian peoples (millennia to 1930s–1950s) — Mediterranean, Middle East, Asia
See full technique reference →During dehydration, water molecules are removed by diffusion and evaporation, lowering the product’s water activity (a_w). The process halts enzymatic reactions and microbial growth once a_w falls below 0.6, while the concentration of sugars, organic acids, and volatile flavor compounds increases, enhancing taste and aroma.
