High prevalence of protein-energy malnutrition among the vulnerable population, especially children has prompted research on fortification of common staple cereal foods such as rice. However, rice has inferior nutritional value compared to other popular cereals, such as maize, therefore limiting its full utilization. Its storage protein, glutelins, is not easily digested by monogastric animals; therefore, food to food fortification of rice flours provides protein nutritional compensation as well as improvement of other nutrients. This study was carried out to determine the proximate and mineral (Fe, Zn, Mg, Ca, P) composition of rice composite flours. Methodology: The blending ratios (rice: maize: sorghum: pumpkin: carrots: baobab: amaranth) used in the study were 70:0:0:7.5:7.5:5:10 (AT1), 45.5:24.5:0:7.5:7.5:5:10 (AT2), 35:35:0:7.5:7.5:5:10 (AT3), 23.3:23.3:23.3:7.5:7.5:5:10 (AT4) and 100% rice flour (AT5). Proximate analyses were performed according to Association of Official Analytical Chemist (AOAC) methods. Atomic absorption spectroscopy was used to determine the minerals. Data analysis was done using Analysis of Variance (ANOVA). Mean comparisons for treatments were done using Bonferroni tests and significance level was set at P≤0.05. Findings: Moisture content of the composite flours ranged from 10.87 to12.55% and was significantly different (p |
