Description
Dry‑roasting spices at 150–200 °C for 5–10 min releases essential oils, initiates Maillard browning, and reduces bitterness, producing a deep, earthy, smoky aroma.
Technical
The process drives thermal degradation of phenolic acids and tannins, volatilizes terpenes such as eugenol and cinnamaldehyde, and promotes Maillard reactions between amino acids and reducing sugars, yielding melanoidins, pyrazines, and other heterocyclic flavor compounds. Heat‑labile antioxidants are preserved at moderate temperatures, while excessive heat leads to acrylamide formation and loss of aromatic terpenes.
