In this study, the functional properties of flour produced from wheat flour and blended with unfermented and fermented sweet potato flour in the following ratios (WF:USPF:FSPF:100:0:0,0:100:0,- 0:0:100,90:10:0,90:0:10) were evaluated. The result obtained showed that fermentation improved the foaming capacity, (2.00% to 8.00%), emulsion capacity (23.66% to 25.72%) and least gelation (6.00% to 10.00%).100% USPF with the highest bulk density of 2.50g/cm3 and the highest oil absorption capacity of 220.00% while 90% WF:10% FSPF with the highest water absorption capacity of 200.00% had the highest swelling capacity of 0.80. The results show that blending wheat flour with fermented sweet potato flour improves the functional properties.
