Abstract

A Preliminary Study on Adulteration Control of Greek Monofloral Honeys Using Isotope Ratio Mass Spectrometry

Author(s): Karabagias IK*, Casiello G and Longobardi F

Isotope ratio mass spectrometry was applied to Greek honeys in order to a) record carbon and nitrogen stable isotopes, since data involving Greek monofloral honeys are very limited and b) screen the degree of adulteration with common sugar at concentrations of 2%, 5% and 10% (w/w). In addition, isotope results were compared with some indicative published data in the literature, involving honeys from different regions, in order to investigate any/or not existing differences, with respect to honey geographical origin. Results showed that adulterated honey samples showed significant differences in carbon isotopic values compared to pure honey (P<0.05). The same holds for the differences recorded between Greek honey and honeys from different regions (P<0.05). The application of IRMS has the potential to provide in a short time of analysis, accurate data regarding identity and quality of honey
