Abstract
Honey is one of the important food commodities due to its nutritional and medicinal values. However, the issue of its quality and authenticity remain as important factors in consumption and marketing. This study was aimed at determining the botanical sources and quality parameters of honey samples collected from different areas of Ethiopia. The botanical sources of honey were analyzed using the melissopalynological method. Sugar profiles were analyzed using HPLC, and physicochemical properties were determined following the harmonized methods of honey analysis. Diverse plant species, including Schefflera abyssinica, Eucalyptus spp., Guizotia abyssinica., Echinops spp., Coffee arabica, Bersama abyssinica, and Rumex spp., were identified as dominant sources of honey. However, honey from the Gimbo district contains no pollen fingerprints, and its source has remained unknown. The average values of honey sugar compositions ranged from 30.3–46.7%, 29.9–40.3%, 15.0–22.2%, and 0.28–4.4% for fructose, glucose, sucrose, and maltose, respectively. Although the quality parameter values of most honeys fit the acceptable range of national and international honey quality standards, honeys collected from Guassa district revealed some abnormal characteristics. This abnormality may be related with poor handling, processing, or suspected for honey adulteration. Thus, regular testing and monitoring of honey quality are crucial in order to maintain its natural properties as well as control the current widespread practice of honey adulteration in Ethiopia.
