| dc.description.abstract | Three brands of infant fonnulas (n = 3) and 618 cow's whole milk samples from four different famls, which supply milk to Addis Ababa, were analyzed for various essential (Ca, Mg Fe, and Zn) and non-essential (Cd, Ni, Pb, and TI) nutrients, fat and protein levels. Known weights of powdered infant fonnulas or freeze dried cow's whole milk samples were digested with 3.5 mL HNO) and 2.0 mL HeIO" on a hot plate for 4:30 h. The contents of nutri ents in the digests were then analyzed employing standard methods. The fo llowing mean levels were recorded in cow's whole milk: Ca (mglL) 1600; Mg (mglL) 65; Fe (mglL) 1.25; Zn (mglL) 5.33; Cd (mglL) 0. 18; Ni (mglL) 1.27; Pb (mglL) 2.63; TI (mglL) 2.15; rat 3.7% (111/m); protein 3.2% (m/m). The data for the mineral concentrations in cow's whole mi lk were found within normal interva ls described in the literature. The three infant fomlUla brands analyzed in this study generally showed low nu tri tional contents when compared with the recommended dietary allowances (RDA) for usc in North America. The observed values of the ana lyzed non-essenti al elements were below the drinking water maximum admissible concentrat ions for the infa nt fomlU las. However, significantly higher concentrations of these clements were observed in the cow's whole milk. An important contribution to the daily intake of calcium for Addis Ababa population due to the consumption of cow's whole milk was observed. The accuracy of ana lyl ical results was checked by analyzing the NIST reference material SRM 8435 (whole milk powder) and good agreement was achieved with certi fi ed values. | en_US |
