What You Need to Know
During sun‑drying, water is removed by evaporation, concentrating sugars, acids, and carotenoids. The breakdown of cell walls increases lycopene bioavailability, while Maillard reactions between reducing sugars and amino acids develop brown pigments and nutty aromas. Oxidative degradation of unsaturated fatty acids can produce off‑tastes if drying is prolonged or temperatures rise above 40 °C.
