Description
A process that toasts, grinds, and combines whole spices to release and preserve volatile flavor compounds.
Technical
Controlled toasting (120–150 °C, 2–5 min) thermally desorbs essential oils while avoiding oxidation of heat‑labile terpenes. Subsequent grinding to 200–400 µm maximizes surface area for solvent extraction, but prolonged grinding generates friction heat that degrades aromatic terpenes and phenolics.
Science
Primary Reaction
Thermal desorption of volatile essential oils and mechanical increase of surface area leading to enhanced solvent‑mediated extraction.
