Purpose Child undernutrition is a persistent problem in Africa, especially in areas where the poor largely depend on starchy staples with limited access to diverse diets. The purpose of this study was to determine the protein quality, growth and rehabilitating potential of composite foods made from quality protein maize. Design/methodology/approach Four composite diets were prepared from quality protein maize, namely quality protein maize-soybeans; quality protein maize-soybeans-cowpeas; quality protein maize-soybeans-common beans and quality protein maize alone. A fifth diet was prepared from common maize alone. The control diet (Chesta®) was made from maize, soybeans, fish, bone and blood meal. The formulations were made to meet the greatest amino acid score and the desired amount of energy and fat according to the FAO/WHO (1985) recommendation for pre-school children. Albino rats were used in evaluating the protein quality of the formulations. Findings The food intake was significantly different (p < 0.05) among diets; with a trend of intake decreasing from quality protein maize-based to conventional maize alone diets (apart from the control diet). Protein efficiency ratio and net protein ratio varied significantly (p < 0.05) across the experimental diets. Protein digestibility-corrected amino acid score (PDCAAS) was 80 per cent (quality protein maize-soybeans-cowpeas), 87 per cent (quality protein maize-soybeans), 103 per cent (common maize alone), 98 per cent (quality protein maize), 80 per cent (quality protein maize-soybeans-common beans) and 53 per cent (control). Research limitations/implications Two diets, namely quality protein maize-soybeans-common beans and quality protein maize-soybeans-cowpeas, showed the greatest potential to support growth and rehabilitation of undernourished rats. Human trial is proposed to validate the findings. Originality/value Despite adoption of quality protein maize in several parts of the country, there are no studies that have been done to determine the potential of quality protein maize to support optimal growth and rehabilitation of undernourished children. The objective of this study was, therefore, to evaluate the protein quality, growth and rehabilitating potential of composite foods made from quality protein maize.

Duration Of Storage

Effect of storage time on the quality of smoked heteroclarias was studied. 108 samples of heteroclarias (average weight 210 + 15g) was used. Analysis carried out include: proximate, mineral composition (Ca, Na, Fe and Mg), biochemical, amino acid and sensory evaluation. Data obtained was subjected to Analysis of Variance (ANOVA) while the sensory data was subjected to nonparametric test (Kruskal Wallis test). Smoked heteroclarias have good nutritional quality in terms of proximate, mineral and amino acids all of which decrease with increase in duration of storage at ambient temperatures. Glutamic acid  was the most predominant amino acid and the highest non-essential amino acid (NEEA), lysine was the most predominant EAA. There was higher concentration of non-essential amino acids than essential amino acids, EAA/NEAA ratio (0.86 – 0.93) recorded indicates that the fish have excellent protein quality; its the predicted protein efficiency ratio (P-PER) ranged between 3.44-3.61 and its biological value ranged between 79.84 -75.04. Its chemical score and TEAA decrease with increase in storage time. Its texture quality reduced significantly (χ2 = 12.207, p<0.01) with increased storage period. It is therefore recommended that smoked heteroclarias be consumed as soon as it is smoked and regularly for good healthy conditions especially among children, aged and other vulnerable groups.
