摘      要：Traditional complementary foods in Africa are cereal-based, low in nutrient-density;hence, causing severe-acute-malnutrition. This study was aimed to formulate and evaluate nutritional quality of complementary foods (CF) using locally available food materials. Yellow maize (raw, germinated & fermented), defatted groundnut (DGF) and ginger flour (GGF) were blended to obtain RDG (76.7% raw yellow maize, 20.8% DGF and 2.5% GGF), GDG (74.4% germinated yellow maize, 23.1% DGF, 2.5% GGF), and FDG (72.6% fermented yellow maize, 24.9% DGF, 2.5% GGF). Food samples were evaluated for nutritional qualities and sensory attributes using standard methods. Protein (g/100 g), energy value (kCal/100 g), total amino acids and essential amino acids (g/100 g protein) of formulated CF ranged from 19.38 to 28.58, 373.49 to 394.53, 87.33 to 91.89 and 36.17 to 37.63, respectively, and were comparable to control (17.07, 401.22, 94.47 & 35.35). Minerals were present in appreciable amount in the foods, while phytate/mineral (Ca, Fe, Zn) and oxalate/calcium molar ratios were lower than critical levels. Bulk density (1.4 - 1.6 g/mL), least gelation (4 - 6%), water absorption capacity (10.5 - 15.8%) and swelling capacity (0.5 - 1.2%) were significantly (p 0.05) lower in formulated CF than in control, except for bulk density. Biological value (78.44%) of FDG was significantly (P 0.05) higher than GDG (78.4%) and RDG (75.87%), respectively, but lower than control (93.48%). Pack cell volume (22.50%), haemoglobin concentration (7.5 g/dL), red blood cell (3 × 103 mm− 3), albumin (3.72 g/dL), total blood protein (5.62 g/dL) and globulin (1.9 g/dL) of rats fed on FDG were significantly (p 0.05) higher than other diets, but comparable to that of control. Kidney (urea, 10.16 mg/dL;creatinine, 4.8 mg/dL) and liver function index (AST/ALT ratio, 0.38) of rats fed on FDG were lower than in those rats fed on RDG, GDG and control. For sensorial attributes, RDG was ranked best next by FDG in appearance,
