Definition

Thermal decomposition of organic material under high heat, producing smaller compounds, gases and char-like products.

Why it matters

This chemistry contributes to color, aroma and flavor formation as roasting progresses.

How it is measured or recognized

Routine roasting infers it from time, temperature, color, gases and sensory or analytical results.

Roasting tip

Reaction families overlap; avoid assigning all flavor development to one event or phase boundary.
