Study of the quality and antibacterial activity of some honeys

Honey is a sweet substance that bees make from the nectar of flowers or honeydew, having varying chemical composition and properties. The aim of this research is screening the antimicrobial effects of eight different honey samples from Algeria . Samples of honey were collected from different areas of Tizi-Ouzou. Samples of honey have been studied for their physicochemical and pollen parameters and their antimicrobial effect on Escherichia coli, Staphylococcus aureus , Pseudomonas aeruginosa , Staphylococs epidermitidis, Listeria inocua Enteococcus fecalis Bacillus cerius .The analyzes carried out on the 8 samples of honey reveal a water content of 16.80 to 22%, an acidic pH of 3.70 to 4.04, an electrical conductivity of 0.26 to 0.85 × 10-4 S / cm and a hydroxymethylfurfural level between 16 to 38.03 mg / kg. These results show that these samples are of good quality compared to international standards. The pollen analysis allowed the identification of different botanical families. According to our results all the honey samples have effectively high antibacterial activity against studded strains.
