Figure 2. — Aroma sensor responses of the A32S sensor array in difference mode. Sensor response percentage differences in e-nose sensor output intensities of individual numbered sensors are indicated for headspace volatiles of good-flavor minus off-flavor catfish meat samples presented as (A) bar graph (indicating differences in normalized sensor values) and (B) line-graph (indicating percent changes in sensor resistance responses relative to baseline resistance). Sensor element numbers represent individual numbered sensors in the e-nose sensor array.
