Effect of drum drying on the physical and chemical characteristics of instant cereal mixes from the blends of millet and sesame fortified with moringa leaf powder

Abstract

The effect of drum drying on the physical and chemical characteristics of instant cereal mixes (ICM) from the blends of millet and sesame fortified with Moringa Leaf Powder (MLP) was investigated. Unfortified instant cereal mixes (uICM) were produced from graded levels of dehulled 0.75 % citric acid depigmented millet (100, 95, 90, 85 and 80 %) and dehulled sesame seed (0, 5, 10, 15, and 20 %), while fortified ICM (fICM) from graded levels of dehulled 0.75 % citric acid depigmented millet (95, 90, 85, 80, and 75 %), dehulled sesame seed (0, 5, 10, 15, and 20 %) and MLP (5 %). Slurries of blends was fed to drum drier to produce ICM and evaluated for physical and chemical properties. The MLP (25.33 %) and DSF (24.19 %) had comparable crude protein contents. The total ash and ether extract contents of DSF was 3.09 and 49.85 %, while MLP had 8.57 and 4.82 %, respectively. The fICM had decreased whiteness values (70.27 to 64.60), while uICM showed increased whiteness (78.18 to 80.77) values. The chemical composition of ICM showed increases in ash (0.68 to 1.75 %), protein (8.05 to 12.74 %), total dietary fiber (0.10 to 16.44 %), pro vitamin A (666.85 to 1184.30 μg/100g) contents and amino acids concentrations which increased with sesame and MLP inclusion. fICM showed higher concentration of amino acids, crude protein, total ash, and total dietary fiber than control sample while uICM showed higher L* values than fICM.
