Abstract

Consumption of nutritionally inadequate diets results in infant malnutrition. This study is aimed at formulating complementary foods from blend of orange-fleshed sweet potato, brown teff, and dark red kidney beans for infants aged 6–23 months. The Design-Expert 6.0.8 Software was used to formulate flour blends. Proximate, mineral, and antinutrient characterizations of flour blends were determined by using standard methods. The crude protein, crude fat, carbohydrate, and energy contents of raw flour blends were varied from 4.90–14.25%, 1.63–1.99%, 67.10–76.29%, and 339.07–343.63 Kcal/100 g, respectively. The crude protein, crude fat, carbohydrate, and energy contents of extruded blends were varied from 3.65–12.41%, 0.16–0.31%, 72.66–83.96%, and 343.07–356.74 Kcal/100 g, respectively. The crude protein, crude fat, carbohydrate, and energy contents of drum-dried blends were varied from 4.45–14.08%, 1.21–1.70%, 69.30–80.45%, and 347.20–356.57 Kcal/100 g, respectively. The products meet the recommended daily intake of protein (5.2–10.9 g), carbohydrate (≥65 g), energy (202–894 Kcal), and potassium (60–160 mg) for infants. However, the products are in short of meeting some of the recommendations given by international standards regarding daily intake of fats and minerals. Therefore, it requires some enhancement by including studied amount of butter and other micronutrient dense foodstuffs.

Highlights

Consumption of nutritionally poor complementary foods and inappropriate feeding practices are the main contributing factors to the development of childhood malnutrition in many developing countries including Ethiopia [1]
The complementary food products were formulated from flour blends of orangefleshed sweet potato (OFSP), brown teff (BT), and dark red kidney beans (DRKB) to complement the nutritional need of infants aged 6–23 months
The extrusion process was more effective in phytate and tannin content reduction than the drum-drying process

Summary

Introduction

Consumption of nutritionally poor complementary foods and inappropriate feeding practices are the main contributing factors to the development of childhood malnutrition in many developing countries including Ethiopia [1]. Traditional infant foods made of cereals are low in protein, fat, vitamin A, zinc, iron, and high in antinutritional factors that reduce nutrients and mineral bioavailability [2]. In Ethiopia, every year, one million children under the age of five years die because of protein-energy malnutrition [5]. Undernutrition is responsible for at least 35% of deaths in children aged under five [6]. 165 million children below five years of age are affected by undernutrition, of which 26% are stunted [8]. Ethiopia’s achievement is limited with an annual reduction of 1.3% [10]
