Abstract
The ability of EOS507C to early detect microbial spoilage of commercial tomato paste and vegetable soup was analyzed. The food products were artificially contaminated with different concentrations of yeasts and bacteria. As shown by PCA, electronic nose was able to discriminate the inoculated samples from the not-contaminated ones within 28 hours from inoculation allowing a sensible reduction in time usually requested by other conventional microbiological methods. GC-MS spectra were produced and the difference in th
