Odorous contaminant in wheat have been detected using a conducting metal oxide semiconductor gas sensor array. Cereal grains contaminated by toxigenic fungi and relative mycotoxins can be detected and quantified using complex extraction procedures and analytical techniques. We studied the wheat odour, the presence of non-grain volatile metabolites due to Fusarium poae contamination for the determination of wheat quality classification by SPME-GC/MS and by electronic nose in order to compare analytical tecnique and sensor array tecnique.
