The assessment of geographical origin of honey is economically important for producers and consumersas every region may present particular quality characteristics. In this study, honeys from the seven differentregions of Buenos Aires province (Argentina) were characterised by their antioxidant capacity (DPPH,FRAP), total phenolic content (TPC), mineral composition, colour and ash. Honeys showed significantdifferences among their antioxidant capacity (DPPH), ash, colour and mineral content (P ≤ 0.05). Besides,a good antioxidant activity and low amounts of Cu and Zn (<1.0?1.5 and 0.7?1.8 mg kg1, respectively)were found in the samples. Significant Pearson?s correlations (P ≤ 0.05) among the different parameterswere found. Moreover, the linear discriminant analysis allowed the classification of honeys in their originalgroups with a prediction success of 98%. The present results suggest that honeys could be correctlyclassified by their geographical origin through their TPC, colour, ash and mineral concentrations.Keywords
