Formulation, Sensory Attributes and Nutrient Content of a Malted Sorghum-based Porridge: Potential for the Management of Moderate Acute Malnutrition among Infants and Young Children

Abstract

Introduction: Substituting corn in a fortified corn-soy blend (CSB+) with enzyme-active sorghum malt has the potential to be used as a suitable alternative supplementary porridge in the management of infants and young children (IYC) with moderate acute malnutrition (MAM) in Uganda. Objective: This study aimed to develop acceptable malted sorghum-based supplementary porridge (MSBP) that meets the energy and protein specifications for the management of IYC with MAM, using locally-available ingredients. Methods: MSBP formulations included the use of malted sorghum flour and extruded soy and corn flour. The ratio of the soy to corn ingredients was 3:7 (F617/F593), 1:1 (F892/F940), and 4:1 for CSB+, which is the standard care for the management of IYC with MAM in Uganda. The sorghum malt content for F617/F892 and F593/F940 was 25% and 30%, respectively. F617, F593, F892 and F940 met international specifications for a supplementary porridge. A comparison of the consumer acceptability scores and viscosity levels of these formulations was made, using analysis of variance. Results and Discussion: The scores for flavour, taste, mouth feel, sweetness and overall consumer acceptability differed among the formulations (p<0.05). F617 had a higher mean acceptability score than F593, F892 and F940 (p<0.05), as well as a higher energy and protein content than CSB+ (p<0.01). The energy density, protein density and viscosity of F617 were 1.6kcal/ g, 4g/100 kcal and 2809 cP, respectively, with a flour rate of 25%. Conclusion: Sorghum malt is suitable for the development of an acceptable supplementary porridge (MSBP). It meets the international energy and protein specifications for the management of IYC with MAM, and the F617 formulation meets these specifications.
