ABSTRACTThis study was conducted to determine the amino acid and macro‐ and micro‐ element profiles of extruded composite foods intended for supplementary feeding of pre‐school age children in Tanzania. Six composite foods, namely corn‐bean‐sardine meal, bean meal, sorghum‐bean‐sardine meal, rice‐bean‐sardine meal, corn‐bean‐sardine‐cassava‐soybean meal and sorghum‐bean‐sardine‐cassava‐soybean meal, were formulated according to the FAO/WHO/UNU guidelines. The foods were evaluated for amino acid content, limiting amino acids and micro‐ and macro‐element concentrations using standard assays. Results showed that the concentrations of the essential amino acids (g/kg crude protein) were His (20–28), Thr (24–35), Val (43–53), Ile (35–46), Leu (78–91), Trp (11–15), Lys (42–57), SAA (17–40) and AAA (62–77). Amino acid score ranged between 68–91%, with Thr, SAA and Lys being the most limiting amino acids. Protein energy and net dietary protein energy values ranged between 12.24–21.00 and 7.2–9.6%, respectively. The average micro‐element concentrations in the composite products (mg/100 g) varied (P...
