Contribution of pyrolysis-mass spectrometry (Py-MS) to authenticity testing of honey

Pyrolysis Mass Spectrometry (Py-MS) was used to investigate discrimination of honey samples from different floral (ten) and geographical (seven) origi ns. The data were analysed statistically (using Principal Component and Dis criminant Factor Analysis) in order to check the possibility of the use of these profiles for characterising the botanical source of honey. Py-MS show ed as a very useful tool for the rapid discrimination of honeys from differ ent botanical origins. Separation of the geographical origin of honey was u nsuccessful and this is likely to be due to the very large and varied botan ical origins of honey located within a single geographical region.
