abstract:
The aim of this work was to investigate the possibility of using various electrical and dielectric parameters to distinguish natural honeys and determine their authenticity. Electrical properties of honey were tested at temperatures between 10oC and 30oC, in an electromagnetic field frequency ranging from 50 Hz to 20 kHz. The determination of permittivity, dielectric loss factor and conductivity for honey makes it possible to distinguish types of honey and check their authenticity. The temperature of a honey sample has a significant effect on the values obtained for the measured electrical properties. Testing should be carried out within a temperature range of 15oC to 25oC. Further research, carried out on a greater quantity and variety of honeys, may lead to the introduction of new effective methods for evaluating the type and quality of natural honey.
