What You Need to Know
The process relies on slow, uniform drying at 30–40 °C, which limits Maillard reactions and retains volatile aroma compounds. Water is removed by evaporation, lowering the moisture content below 10 % and creating a hostile environment for microbes. The mild temperature preserves heat‑labile nutrients such as vitamin B6 and niacin, and protects carotenoids from oxidation.
