Differentiation of Blossom Honey and Honeydew Honey from Northwest Spain

The knowledge of important parameters for honey characterization is an increasing requirement of consumers and the honey industry. In this respect, differentiation between blossom honeys and some honeydew honeys is still an unresolved task. This study includes the results of physicochemical and melissopalynological analysis of 86 honey samples from north-western Spain. The relationship between the microscopic elements in honey, such as Metschnikowia cells and fungal spores from plant pathogens, together with their physicochemical parameters were analysed. A cluster analysis was performed to differentiate blossom honey samples from honeydew samples. Metschnikowia cells and certain fungal spores were found to be good variables to enable differentiation between blossom honeys and honeydew honeys.
