Flour mixes obtained by the addition of banana pulp in various proportions (0–50%) to maize ‘extracts’ were evaluated for some quality characteristics. All the mixes had significantly lower values of crude protein, fat and water-holding capacity. Gelation, however, significantly increased the water-holding capacity in all cases. The ash content, titratable acidity and total sugars increased tremendously with an increase in the level of banana substitution. While both Adam's consistency values and equilibrium moisture content decreased with an increase in the level of banana substitution, the syneresis values did not show any consistent pattern. The consistently low moisture content and the results of the moisture sorption isotherms suggest a good storage stability of all the mixes, especially when kept under conditions of water activity of 0.30 and below, and their possible suitability for baked products.
