dc.description.abstractHoney with Bupleurum spinosum (zandaz) as a main pollen source has not been the subject of previous detailed study. Therefore, twelve Moroccan samples of this honey were subjected to melissopalynological, physicochemical and micro-biological quality characterization, as well as antioxidant activity assessment. From a quality point of view, almost all samples were within the limits established by Codex Alimentarius, and/or the European legislation. All samples presented predominance of B. spinosum pollen (more than 48%). Relatively high levels of trehalose (1.3–4.0 g/100 g) and elezitose (1.5–2.8 g/100 g) were detected. Those sugars, not common in monofloral honeys, could be used as na important factor to discriminate zandaz honey. Flavonoid content correlated positively with the honey color, melanoidin and polyphenol content, and negatively with the IC50 values of scavenging ABTS (2,2´-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) free radicals, while proline amount correlated negatively with IC50 values of nitric oxide scavenging activity and chelating power. This correlation supports the use of anti-oxidant activities as important variables for PCA (principal component analysis). Both components explained 70% from the given data, and showed certain homogeneity upon analyzed samples independent of the region, suggesting the importance of B. spinosum nectar in the resulting honey characteristics.pt_PT
dc.description.abstractResumo La miel con Bupleurum spinosum (pendejo) como principal fuente de polen no ha sido objeto de un estudio detallado previo. Por lo tanto, doce muestras marroquíes de esta miel fueron sometidas a una caracterización melisopalinológica, físico-química y microbiológica, así como a la evaluación de su actividad antioxidante. Desde el punto de vista de la calidad, casi todas las muestras estaban dentro de los límites establecidos por el Codex Alimentarius y/o la legislación europea. Todas las muestras presentaron predominio de polen de B. spinosum (más del 48%). Se detectaron niveles relativamente altos de trehalosa (1.3-4.0 g/100 g) y melecitosa (1.5-2.8 g/100 g). Esos azúcares, no comunes en mieles monoflorales, podrían ser utilizados como un factor importante para discriminar la miel de pendejo. El contenido de flavonoides se correlacionó positivamente con el color de la miel, el contenido de melanoidina y polifenol y negativamente con los valores de IC50 de la actividad de barrido de los radicales libres de ABTS (2,2’-azino-bis (3-etilbenzotia-zolina-6-sulfónico), mientras que la cantidad de prolina se correlacionó negativamente con los valores de IC50 de la actividad de barrido de ON (óxido nítrico) y el poder quelante. Esta correlación apoya el uso de las actividades antioxidantes como variables importantes para el APC (análisis de componentes principales). Ambos componentes explican el 70% de los datos obtenidos y muestran cierta homogeneidad en las muestras analizadas independientemente de la región, lo que sugiere la importancia del néctar de B. spinosum en las características de la miel resultante.pt_PT
