“…Our results generally confirm that the fermentation rate is very low in the analyzed samples. Moisture values observed for our samples were slightly lower than those obtained for Córdoba (Argentina) honeys [25] and quite similar to honeys from Buenos Aires Region [30], and to those of Andalusia (Spain) [26], Lazio Region (Italy) [24], Serbian Acacia honeys [27] and to Entre-Douro e Minho Region of Portugal [31]. …”

BackgroundThe levels of 19 elements (As, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Tl, U, V, Zn) from sixteen different Argentine production sites of unifloral [eucalyptus (Eucaliptus rostrata), chilca (Baccharis salicifolia), Algarrobo (Prosopis sp.), mistol (Ziziphus mistol) and citric] and multifloral honeys were measured with the aim to test the quality of the selected samples. Typical quality parameters of honeys were also determined (pH, sugar content, moisture). Mineral elements were determined by using inductively coupled plasma mass spectrometer (ICP-MS DRC). We also evaluated the suitability of honey as a possible biomonitor of environmental pollution. Thus, the sites were classified through cluster analysis (CA) and then pattern recognition methods such as Principal Component Analysis (PCA) and discriminant analysis (DA) were applied.ResultsMean values for quality parameters were: pH, 4.12 and 3.81; sugar 82.1 and 82.0 °brix; moisture, 16.90 and 17.00% for unifloral and multifloral honeys respectively. The water content showed good maturity. Likewise, the other parameters confirmed the good quality of the honeys analysed. Potassium was quantitatively the most abundant metal, accounting for 92,5% of the total metal contents with an average concentration of 832.0 and 816.2 μg g-1 for unifloral and multifloral honeys respectively. Sodium was the second most abundant major metal in honeys with a mean value of 32.16 and 33.19 μg g-1 for unifloral and multifloral honeys respectively. Mg, Ca, Fe, Mn, Zn and Cu were present at low-intermediate concentrations. For the other 11 trace elements determined in this study (As, Be, Cd, Co, Cr, Ni, Pb, Se, Tl, U and V), the mean concentrations were very low or below of the LODs. The sites were classified through CA by using elements’ and physicochemical parameters data, then DA on the PCA factors was applied. Dendrograms identified three main groups. PCA explained 52.03% of the total variability with the first two factors.ConclusionsIn general, there are no evidences of pollution for the analysed honeys. The analytical results obtained for the Argentine honeys indicate the products’ high quality. In fact, most of the toxic elements were below LODs. The chemometric analysis combining CA, DA and PCA showed their aptness as useful tools for honey’s classification. Eventually, this study confirms that the use of honey as biomonitor of environmental contamination is not reliable for sites with low levels of contamination.

“…Chemometrics has also been used for the determination of the geographical origin of honey in combination with physicochemical data and other properties, that include basic parameters such as water content and electrical conductivity (Anklam, 1998;Silvano et al, 2014;Fechner et al, 2016). However, the antioxidant potential has rarely been used (Patrignani et al, 2015) to assess the origins of the honey or to discriminate between honeys coming from different locations.…”

Multifloral honeys produced in the Marche region (Italy) were analysed leading to the antioxidant and colour characterisation of this type of regional honeys: the antioxidant activity was determined measuring total phenolic content (TPC), and using ABTS and DPPH assays. The elaboration of data with multivariate analyses enabled differentiation of the geographical origin of honey samples, namely as coming from the Mid/Coastal Hilly or from the High Hilly/Submountain belt of the Marche region. The cluster analysis applied to a selection of samples divided honeys belonging to the Mid/Coastal Hilly belt into three groups showing low, medium and high antioxidant activity and in part located in different areas of the region. Finally, using data of unifloral honeys from the Marche region previously determined, it was possible to have an indication of the prevalent nectar contained in most of the multifloral honey samples harvested in 2012 in the Marche region.
