Studies On Commercially Available Enset (ensete Ventricosum (welw.) Cheesman) Food Products (kocho And Bulla) For Major Minor And Trace Elements

Kocho and Bulla are starchy foods obtained from fermenting edible part of the leaf sheath and corm of enset plant (Ensete ventricosum (Welw.), Cheesman). In the present study the level of selected metals (Na, Mg, Mn, Ni, Pb, K, Ca, Fe, Zn, Cu, Co, Cr, Cd) in Kocho and Bulla sampled from different supermarkets of Woliso (Oromiya region) and Welkite (SNNPRG) of Ethiopia were analyzed. Known weight of oven dried Kocho and Bulla samples were digested by wet digestion using 2 mL of HNO3 and 2 mL of HCLO4 for 2 h at variable temperature (120 - 270 oC). The contents of the minerals in the digests were analysed using flame atomic absorption spectrometer. The following concentration ranges (μg/g) were recorded in Kocho and Bulla, respectively: K (2753 – 4380) and (708 – 875); Na (462 – 688) and (402 – 442); Ca (498 - 584) and (385 - 446) ; Mg (180 - 290) and (58.4 - 89.5); Fe (92.5 -135) and (36.5 - 59.8); Zn (31 - 32.08) and (22 -44.3); Cu (3.4 – 4.3) and (2.01 - 3.53); Mn (8.58 -10.13) and (1.0 - 4.98); Ni (≤ 5.61) and (
