Abstract
Despite the need for Iron and Folic acid (IFA) during critical stages of child development and gestation, there is observed persistence in deficiencies despite several interventions. This situation motivated a food-based approach using IFAfortified NARO Bean-3 (NABE-3 bean) and silverfish. IFA fortified composite flours with NABE-3 (BF): silver fish flour (SFF) proportions as 100% BF, 90% BF: 10% SFF, 80% BF: 20% SFF, and 70% BF: 30% SFF were developed. Functional, pasting, and sensory properties were assessed using standard methods. Increasing silverfish proportions in the composite flours was associated with decreased water absorption properties of the composite flours indicating reduced reconstitution abilities; reduced final viscosity but increased bulk density implying a high density of nutrients at lower viscosity and volume; and increased peak time indicating increased cooking energy requirements. The compressibility and Hausner ratios of the flours were high and not significantly different, indicating low flowability of the bean flour and its composites with silver fish. Increasing silverfish proportions reduced sensory score from liked moderately to indifferent on a 9-point hedonic scale due to colour darkening, and increased intensity of fishy aroma and flavour. The 90% BF: 10% SFF and 80% BF: 20% SFF composites were more acceptable than the 70% BF: 30% SFF. However, all the composites were more acceptable than the control 100% BF: 0% SFF. Incorporation of silver fish into NABE bean flour generally leads to increased sensory acceptability and nutrient density but reduced functionality.
