Abstract : The objective of this work is the evaluation of the quality of eight honeys randomly selected from the wilayas of Jijel, Souk Ahras, Biskra, Batna, Mascara, Annaba, El Tarf, and Guelma based on a physicochemical study and a melissopalynological analysis. The pollen and physicochemical analysis (pH, electrical conductivity, and free acidity) of the honey samples was carried out using the method established by the International Commission for Plant-Pollinator Relationships. The physicochemical analyses showed that the pH of the honeys studied varied between 3.8 and 4.23, with an average of 4.02. Therefore, all the honeys analyzed are acidic and come from nectar. In addition, the electrical conductivity revealed values oscillating between 204 µs/cm and 566µs/cm. The free acidity has marked varied values of 30 and 62 meq /Kg, with an average of about 47meq/kg. In contrast, the pollen analysis revealed that the honeys of Souk-Ahras and Jijel presented the highest numbers of taxa compared to the other honeys, that is, 18 and 16, respectively. Among the 8 honeys analyzed, the honeys of El Tarf and Guelma were monofloral, represented by Solanum lycopersicum L. and Calendula officinalis L., and the rest of the honey samples were without apparent dominance of a honey type. This study highlights the importance of honey characterization to guarantee authenticity and valorize local production.
