Chemical and Functional Properties of Zea mays Semolina Fortified with Vigna subterranea (L.) Verde Chemical and Functional Properties of Zea mays Semolina Fortified with Vigna subterranea (L.) Verde

Abstract

Analysis was carried out on the sensory, mineral, functional, and proximate properties of maize semolina fortified with bambara groundnut flour using different formulations. The sensory evaluation of maize semolina fortified with bambara nut flours was carried out using the different formulations. Sample MWB which is sample produced between 40% maize, 40% wheat and 20% bambara nut flours. It had 7.60% color, 7.90% flavor, 6.90% taste, 8.50% texture, and 9.00% acceptability, respectively. The calcium, magnesium, iron, zinc, and phosphorus contents were 92.59 mg/kg, 179.46 mg/kg, 300.58 mg/kg, 16.35 mg/kg, and 6.80 mg/kg, respectively. For the functional properties, the oil absorption capacity (g/g) was 6.0, water absorption capacity (g/g) was 7.80, emulsion capacity was 54.00%, gelation capacity was 22.60%, foam capacity was 48.30%, and bulk density was 0.78 g/ml. The moisture content, ash content, crude fat, crude fiber, and the crude protein composition were 12.29%, 1.60%, 5.60%, 3.80%, 17.38%, and 59.33% carbohydrate, respectively. The results showed that the nutritive value of bambara nut flour incorporated into maize semolina flour can be used to supply protein to the human diet.
