Description
Sun‑dried tomato concentration is a low‑tech dehydration technique that harnesses solar radiation to reduce moisture content, thereby concentrating sugars, acids, and pigments while preserving key aroma compounds.
Technical
The process removes water at 30–40 °C over 3–7 days, concentrating sugars to 12–15 % w/w and increasing lycopene by 2–3× through chlorophyll oxidation. Residual moisture of 30–35 % limits enzymatic browning but can support mold if humidity exceeds 60 %.
Science
Primary Reaction
