ORGANIC ACIDS AND PHYSICO-CHEMICAL PARAMETERS OF ROMANIAN SUNFLOWER HONEY

The samples of sunflower honey collected from Romania were analyzed in order to characterize them from the physico-chemical point of view. Melissopalynological analysis, together with the determination of organic acids and physico-chemical parameters (color, moisture, free acidity, pH, electrical co...
