Composition of Ghanian fermented maize meal and the effect of soya fortification on sensory properties

Abstract

There were no significant differences in the composition of four fermented maize doughs used by different ethnic groups in Ghana. The average maize dough contained 49.6% moisture, 37.5% starch and had a titratable acidity of 4.3 mg NaOH g−1 and pH of 3.76. Fermented maize dough (48% m.c.) was fortified with defatted soya flour at 50, 100, 150 and 200 g kg−1 on a replacement basis and used in two traditional food products. Triangle taste tests indicated a significant difference between the control and samples fortified with 10% or more soya flour. Based on a preference test, maize dough products with up to 10% added soya flour were acceptable to Ghanaians
