Multielement profile of Italian oak (Quercus frainetto Ten.) honeydew honey

Italian oak (Quercus frainetto Ten.) honeydew honey production is characteristic for geographical region of Požega 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 mediation of plant sucking insects. Our previous studies showed that Italian oak honeydew honey is characterised with negative specific rotation, unspecific for honeydew honeys and very high phenolic content and antioxidant capacity. The objective of this study was, through the macro and micro element determination in 10 Italian oak honeydew honey samples from two production seasons ; contribute to overall characterisation of this specific honey type. The most abundant element was potassium with average value 3110.9 mg/kg, followed by phosphorus, magnesium and calcium with average values 228.9 mg/kg, 190.5 mg/kg and 134.5 mg/kg, respectively. Determined manganese concentrations from 15.7 mg/kg to 43.7 mg/kg are significantly higher than manganese concentrations in other honeydew honey types available in the literature. The content of potentially toxic elements (Cr, Cd, Pb) was very low or bellow limit of detection, with exception of one sample that, besides higher concentrations of mentioned elements, had increased concentrations of Fe, Zn and Al indicating the improper storage conditions of honey.
