ABSTRACT: The aims of the present study were to assess the quality of local honey samples and discriminate pure and adulterated ones. The samples were analyzed for physicochemical parameters including pH, free acidity, moisture content, ash content, electrical conductivity, reducing sugars, sucrose content, and HMF content. The pH values ranged from 3.40 to 4.65 while the free acidity varied from 3.99 to 45.17 meq/kg of honey. The electrical conductivity (0.13 - 0.56 mS/cm), ash content (0.09 - 0.54 %), reducing sugars (50.31 – 79.56 %), sucrose content (2.24 – 12.21 %), moisture content (17.56 – 22.57 %), and HMF content (8.32-45.26 mg/kg of honey) were detected. During preliminary assessment, the commonly added adulterants by honey traders were identified and quick test methods suitable for local honey samples have been developed. Results obtained from this study showed that all honey samples obtained from apiary sites and many of commercial samples collected from local markets in the study area are of good quality and met the national and international standard limits. However, the physicochemical test results for some honey samples collected from local markets had higher level of certain parameters than recommended suggesting some level of adulteration is practiced by few honey traders.
