| dc.description.abstract | The qualities of 12 Ethi opian multiflora l honey samples were evaluated in terms of common phys icochem ical parameters namely: mo isture content, pH, free acidity, lactonic ac idity and total acidity. The values for studied quality parameters were moisture content, 14.23-19.2%; pH, 3 A-4 .8; free ac idity, 30.6-97.6 meq/Kg; lactonic ac idity, 8.06- 14Ameq/Kg and total acid ity, 42.96-107Ameq/Kg. The analyzed samples showed proper maturity, absence of undesirable fermentation «20% of moisture content), and were 111 agreement with standard values (Codex Alimentricus) and reported literatures. The concentrations of trace heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Z n) in the 12 multifloral honey samples collected from different regions of Ethi opia were also eva luated using flame absorption spectrometry after wet di gestion. The accuracy of the method was assessed by spiking honey samples with known amounts of standard meta ls, and examining recovery. Trace heavy metal contents in the honey samples were found to be in the range of NO-O.O 17 flg/g (Cd), NO-0.15 J.lg/g (Cr), 0.02-1.15 J.lg/g (Cu), NO-7.29 flg/g (Mn), NO (Ni), NO-2.53 J.lg/g (Pb) and 9.96- 16.03 J.lg/g (Zn). Results obtained were in agreement with data reported e lsewhere in literatu re.
