“…In the case of honey samples analyzed, the pH ranged between 3.92 and 4.62. These values were similar to those previously reported in other honeys (Fechner et al 2016, Chuttong et al 2016. The highest levels of pH were observed in the case of honeydew honeys while willow had the lowest level of pH.…”

The present study reveals the utility of high-performance thin-layer chromatographic (HPTLC) fingerprinting of phenolic constituents for the authentication of monofloral honeys. The obtained data enables a more complete assessment of honey quality and the identification of emerging threats to honey quality. The developed procedure facilitates differentiation of varietal honeys and detection of honey adulterations. We used an HPTLC fingerprint analysis to determine the characteristic patterns of different honey types (willow, buckwheat, heather, pine honeydew, and manuka honey). The HPTLC chromatograms were used to determine the differences in the botanical origin of the honey samples on the basis of the band profiles, which are characteristic for each honey type. Identification of 11 polyphenols was performed by comparison of the color and R f of the bands with available standards. Additionally, the results were confirmed by an HPLC analysis.

“…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.

“…Cabe señalar también que la ubicación de los apiarios por zona geográfica, el clima y las condiciones ambientales influyen en la tasa de crecimiento de los ácaros e implica mayor tiempo de flujo climático y periodos más largos de cría, reflejados en la calidad de la miel (35,36) . Además del modelo de extensión utilizado, existen otros factores que pueden estar influyendo en la adopción de BPPM y que valdría la pena profundizar más en el análisis de estas causas en futuras investigaciones.…”

Resumen:Los objetivos fueron analizar los cambios en la adopción de buenas prácticas de producción de miel (BPPM) en productores apícolas de la Península de Yucatán, México, antes y después de haber recibido asesoría técnica y capacitación; así como la identificación de factores que inciden en la adopción de dichas prácticas. Considerando 31 BPPM agrupadas en siete categorías, se calculó el índice de adopción de BPPM (InABPPM). Se analizó información de 8,074 apicultores en dos momentos (línea base y línea final), para los estados de Yucatán (n= 3,840), Campeche (n= 3,525) y Quintana Roo (n= 709). Los apicultores se clasificaron de acuerdo al número de colmenas que poseían en: pequeños (1-22, 24 %), medianos (23-35,
