Abstract: Green coffee was roasted in a laboratory scale fluidized bed roaster to a fixed end point (dark roast) using different roasting temperatures (isothermal roasting) - 228°C, 238°C, 248°C and 258°C. The formation kinetics of selected ion masses were monitored on-line by PTR-MS. Strong differences in the formation kinetics of compounds underlying the ion masses were observed, as a function of roasting temperature.
