Abstract

The mineral content, essential amino acids and selected functional properties of composite blend of maize flour (MF) and boiled bambara groundnut flour (BGF) in the ratio 70:30 w/w were investigated using standard processing technique. Results obtained showed that maize flour blended with 30% bambara groundnut in addition to germination significantly improved the mineral and amino acids profile of the composite blend. Functional properties (bulk density, water absorption capacity and foam capacity) were also affected by fermentation, which significantly lowered the water absorption capacity and bulk density increased the foam capacity of bambara-maize‘ogi’. Sensory evaluation indicated that the bambara-maize‘ogi’ was generally acceptable. The application of bambara groundnut blend to traditional foods suggests a viable option for promoting the nutritional qualities of Africa maize-based traditional foods with acceptable cooking qualities.

Key words: Fermented maize flour, bambara groundnut, mineralcontent, functional properties.
