What You Need to Know
Photothermal energy converts liquid water to vapor (enthalpy of vaporization ~2260 kJ/kg), with concurrent enzymatic browning (polyphenol oxidase activity) and Maillard reactions (at >30°C) creating depth. Carotenoid pigments (capsanthin in chilies, allicin in garlic) concentrate as moisture content drops below 15%.
Intensifies flavor potency while developing complex secondary notes, critical for berbere's layered heat and umami foundation.
