Some quality parameters of selected Croatian honeys

In this study, honey samples of known botanical origin from different regions of Croatia were investigated. The rheological properties and colour of four types of honey from acacia, chestnut, lime and sage were examined for their potential use as characterization parameters. The rheological measurements of honey samples were carried out on rotational viscometer over a certain range of temperatures (5 to 40 °C). The viscosity was measured as a function of the shear rate. For all examined data, Newton's law of viscosity was found to adequately describe the flow behaviour of honey samples. The temperature effect on the viscosity followed an Arrhenius-type relationship. Colour was estimated by tristimulus colorimeter CR 300, in CIE Lab, LCh° and Hunter scale. Statistical analysis of data between mean values of L parameters has shown significant difference in colour between selected types of honey.
