PHYSICO-CHEMICAL PARAMETERS OF ROMANIAN RASPBERRY HONEY

Six samples of raspberry honey collected from different regions of Romania were analysed in order to confirm that they are classified as monofloral honey. Melissopalynological analysis, alongside the determination of physico-chemical parameters - moisture, pH, free acidity, electrical conductivity,...
