An electronic nose was used in conjunction with a human panel and artificial neural networks to predict human assessments on a hedonic (pleasantness) scale when confronted with mushroom substrate odors. Both laboratory and field odor samples were collected and presented to both the electronic nose and the human panelists. The human panelists were required to rate the odor samples on a hedonic scale. Neural networks were developed to predict the odor pleasantness based on electronic nose readings. The results obtained from the developed neural networks show promise in the utility of electronic nose evaluation of odors.(Download PDF) (Export to EndNotes)
