Abstract:
Local honeys sold in public markets, small shops or by individuals are not controlled by public services. Currently, information about its quality is non-existent. The objective of this work was therefore to assess the quality of local honeys marketed in Korhogo town. Samples were collected from twenty local honey sellers located in markets and certain neighborhoods of Korhogo town. Then, their physicochemical parameters were determined. The results showed the existence of significant difference (p < 0.5) between the honey samples for all the parameters studied. The amber colored samples (86 – 113 mm Pfund) were the most numerous (55%) compared to the light amber colored ones and the dark colored ones. The electrical conductivity of these honeys oscillated between 115.67 and 765.67 µS/cm. The refractive index, degree brix and density ranged from 1.4884 to 1.5014; 79.15 to 84.45% and 1.4085 to 1.4442, respectively. The values of moisture content varied between 14.15 and 19.23 g/100g, those of pH and free acidity ranged from 3.42 to 4.49 and from 10.67 to 28.89 meq.kg-1, respectively and those of total acidity and hydroxymethylfurfural content oscillated respectively from 14.67 to 40.22 meq.kg-1 and from 0.56 to 30.05 mg.kg-1. All these physicochemical parameters varied within the limits proposed by the Codex Alimentarius Commission. This suggests that the honeys marketed in Korhogo town meet the quality criteria required for its consumption. However, for further study, their nutrients should be identified and quantified, and their microbiological quality assessed.
