Results of radical scavenging activity are consistent with those obtained from measurement of total phenolics. In fact RSA values were significantly higher (p 0.05) in crust than in the crumb for all the samples. A good correlation between total phenolics content and radical scavenging activity was obtained (p 0.001, R2 ¼0.98). As expected, the radical scavenging activity increased with increasing ginger percentage and also therewas a higher ability by the extracts from the crust than those from crumb to scavenge the DPPH radical.
