Sun‑dried and salted bush tomatoes rapidly dehydrate and are osmotic‑treated to preserve moisture‑sensitive nutrients.
Origin: Bantu‑speaking communities (Traditional) — Lake Victoria basin
See full technique reference →The process removes water by solar heat, lowering water activity below 0.6, while salt creates an osmotic gradient that further reduces a_w to ~0.55. This dual action suppresses bacterial, yeast, and mold growth while concentrating sugars and carotenoids such as lycopene.
