Evaluation of Physico Chemical Qualities of Beeswax in Selected Districts of Kafa Zone, Southern Nations Nationalities and Peoples Region (SNNPR), Ethiopia
The study was conducted in selected districts of Kafa Zone of Southern Nations Nationalities and Peoples Region (SNNPR), Ethiopia with an intention to identify the physico chemical quality status of beeswax produced in the areas. Three districts; Chena, Gimbo and Gesha and three peasant associations (PAs) from each district were purposively selected based on their potentialities for production and marketing of honey and beeswax. Before collecting sample beeswaxes, a preliminary survey was conducted to identify the major actors taking part in production, processing and marketing of beeswax. Accordingly, beeswax samples were collected from fresh combs, old combs, local mead houses and cooperatives for detail quality analysis. The Mean + SE value for melting point, refractive index, ash content, total volatile matter, acid value, Saponification value, ester value, and ester to acid ratio of beeswax of the area is found to be 62.35 + 0.15, 1.4416 + 0.0001, 0.0857 + 0.0144, 0.4156 + 0.0385,22.689 + 0.3793,94.7540 + 0.8617,72.065 + 0.4766,3.201 + 0.0625 respectively. All the samples passed for paraffin and other waxes, and fats and fatty acid tests. The result shows no significant variation among studied districts in all parameters. However, significantly higher value of refractive index, total volatile matters and ash contents were recorded in samples from local mead houses at p<0.05. This might be due to poor handling practices and an intentional addition of foreign materials such as salt for preserving beeswax from wax moths’ attacks and ‘kocho’ for increasing its volume which are commonly practiced by some individuals of ‘tej’ houses. The overall results revealed that all the beeswax samples collected from various sources are found within the acceptable ranges of national and international standards.
