The honey used for the study was honeydew honey obtained in 2010 from the region of the Świętokrzyskie Mountains. Dielectric properties of strained honey were determined: relative electric permittivity ε_r (–) and dielectric loss coefficient tg δ (–). The effect of water content in the honey on its electric properties was studied by analysing samples of honey with water content in the range of 17.6-24.4% (9 measurement points). Also tested was the effect of overheating of honey sample, to temperatures of 70 and 90^oC, on the electric and dielectric properties under analysis (the sample was placed in a controlled climate chamber for a period of 24 hours). In addition, the values of the electric properties obtained for the honeydew honey were compared with those for a product obtained through bee-feeding with inverted sugar syrup (Apiinvert). Based on analysis of the results obtained it was concluded that assays of electric permittivity and dielectric loss coefficient of honey permit the estimation of its quality. In particular, the values of the two parameters, and especially the dielectric loss coefficient, change notably as a result of honey overheating in the process of its de-crystallisation. Increase in water content causes an increase in the values of both the dielectric loss coefficient and the electric permittivity. Particularly notable differences can be observed at water content above 21%. The electric properties studied differentiate honeydew honey from a product produced by bees as a result of their feeding with inverted sugar syrup.
