Proximate compositions and physico-chemical characteristics of different brands of evaporated milks in Nigeria were determined using standard methods. The moisture content ranged between 68.85 % and 71.86 %, the ash content 1.32 %-1.96 %, the fat content 7.52 %-8.83 %, the percentage protein 7.65 %-11.42 % and the percentage carbohydrate 7.67 %-11.34 %. Acidity levels (0.50-0.72 %) of all the samples were above the 0.45 % lactic acid minimum literature value, while the energy value ranged between 602.80 KJ/100 g and 676.45 KJ/100 g. The milk samples were also analyzed for some important minerals, viz:- Zn, Fe, Mg, and Ca using Graphite Furnace Atomic Absorption Spectroscopy (FAAS). The levels of these elements were; Zn (4.15-17.85 µg/g); Fe (0.14-1.42 µg/g); Mg (296.00-371.50 µg/g) and Ca (1165.00-1335.50 µg/g) with few exceptions. The results obtained show good agreement with literature values and provide information on the nutritional value of some of the common evaporated milks sold on Nigerian markets.
