Characterization of honey in terms of physicochemical parameters and trace heavy metals, Amhara region
Esubalew Adugnaa and Ariaya Hymetea
Addis Ababa University, Ethiopia
The qualities of Ethiopian, Amhara region, multifloral honey samples were evaluated for moisture content, pH, free acidity,
lactonic, total acidity and trace heavy metals. The values for quality parameters were in range of moisture content, 14.56-
19.20%, pH, 4.50-4.80, free acidity, 33.33-42.60meq Kg-1, lactonic acidity, 8.43-10.86meq Kg-1 and total acidity, 44.19-51.06meq
Kg-1 . The concentration of trace heavy metals (Cr, Cu, Mn, Ni, Pb and Zn) were also evaluated using flame atomic absorption
spectrometer after wet digestion. The contents of trace metals in honey samples were in the range of 0.15-6.66 μg g-1, 0.02-
0.32 μg g-1, 0.36-7.29 μg g-1, ND, ND-2.53 μg g-1 and 9.96-14.62 μg g-1 for Cr, Cu, Mn, Pb and Zn, respectively. The accuracy
of the method was assessed by spiking honey samples with known amounts of standard metals, and examining recovery.
The analytical data showed a significant difference in honey trace heavy metal concentrations and studied physicochemical
parameters. The results obtained were in agreement with data reported in other literatures.
