Food-to-food fortification to refined sorghum flour (SF) for porridge making has an influence on the desirable properties of the porridge. In view of this, the effects of Bambara groundnut (BG) (15%, 25%, 35%) and dried butternut (BU) powder (23%) blending on functional and sensory properties of porridge were investigated using 100%SF as a control. With the blending by BG and BU, water binding capacity (WBC), water solubility index (WSI), oil absorption capacity (OAC) and gel water solubility index (GSI) increased (p 0.05) and specks appearance is very low in all porridges. The porridges color varied significantly (p < 0.05) and less brownness and high yellowness was observed in the blended flours than for the control sorghum flour. Even though improvement in the functional properties with the blending levels at 25% and 35% BG to the sorghum flours was observed, porridge over all aroma and aftertaste was superior for the refined 100% sorghum flour porridge.
