| dc.description.abstract | Peanut (Arachis hypogaea L.) is an important legume oilseed. Peanut is mainly used to make oils and can be consumed directly (roasted and salted) or processed into oil or cake. Peanut is nutrient rich source of protein, fat, vitamin and minerals. The main objective of this study was to determine some selected metals in peanut seeds cultivated in three different areas in Ethiopia. The peanut seed samples were collected from Babile (Oromia region), Dibate (Benishangul Gumuz region) and Zala Mela (SNNP) of Ethiopia. After the pretreatment, the samples were digested for optimized volume of reagent, temperature and time. FAAS was used to determine the metals. The accuracy of the optimized procedure was evaluated by analyzing the digestion of spiked samples with standard solution and percentage recoveries varied from 90.5 to 98. The concentration of metals in peanut seed samples were in the following range. Ca (48.4-83.4), Fe (9.3-11.3), Mn (3.15-7.3), Na (784.7-1146), Pb (1.59-1.96) and Zn (12.2-19.3) mg/kg, respectively. The concentration of Cd, Cu and Ni is below detection limit. ANOVA indicated that there is no significant difference between the mean concentrations of Fe among the peanut seed samples at 95% confidence. There is good correlation between Na-Ca, Mn-Na, Fe-Ca, Mn-Ca and Mn-Fe. Poor correlations were observed between Fe-Zn, Mn-Zn, Pb-Fe and Zn-Ca. | en_US |
