Table 2 also shows that green coffee did not have the same TEMPO radical scavenge capacity as roasted coffee brew extracts. In particular, TEMPO scavenging was highest among the dark roasted coffees, regardless of the geographic location where the coffee beans were sourced. Taken together, these results indicate that phenolic compounds in green coffee beans that are more reactive in both the NO reducing test and Frémy’s salt were lost during roasting and likely transformed to compounds that were more responsive in the TEMPO radical assay.
