Sažetak
Quercus frainetto honeydew honey production is characteristic of the geographical region of Pozega valley, Croatia. This honeydew honey is produced in a specific way, from sweet fruit sap formed at the place where green acorns were discarded, without the mediation of plant sucking insects. The aim of this study was to determine physicochemical parameters, antioxidant capacity, multielement profile, melissopalynological and sensory analysis of this specific honey type. The results showed that Q. frainetto honeydew honey is characterised with high free acidity (51.7 ± 5.5mmol/kg), negative specific rotation (-8.9 ± 2.0), and dark colour (122 ± 15mm Pfund). It possesses high phenolic content (507.6 ± 71.8mg gallic acid/kg) as well as high antioxidant capacity determined by FRAP (1093.9 ± 84.7 mM Fe(II)) and DPPH assay (IC50 3.55 ± 0.48 mg/mL). From analysed macro and micro elements, high manganese content (33.038 ± 6.053 mg/kg) should be noted. The sensory profile is characteristic of honeydew honey with emphasised acidity and persistence/aftertaste.
