Physicochemical properties and pollen analyzes of some Algerian honeys

The samples of 25 honeys, collected from Bordj Bou Arreridj beekeepers, were analyzed for parameters such as pH, free acidity, moisture content, diastase activity, hydroxymethylfurfural (HMF) content, electrical conductivity, polyphenol, flavonoid, proline and proteins, in addition, melissopalynological analyses were carried out for characterization of honeys. The mean values of analyzed honeys were: pH 4.59, moisture 16.81%, free acidity 12.88 mmol/kg, electrical conductivity 0.513 mS/cm, diastase activity 129.49 DN and HMF below11.40 mg/kg, Ash 0.12 mg/kg, polyphenol content 75.28 mg Gallic acid equivalent / 100g, flavonoids content 30.55 mg quercetin equivalent /100 g, insoluble matter 0.46%, proteins 3.05 mg/g, proline 4.07 mg / Kg. The melissopalynological analyzes showed that all honeys were polyfloral. The results of physicochemical parameters, all of the analyzed honeys were found to meet European Legislation.amongst four species of seaweed.
