Values are expressed as mean ± SD from three independent analyses of PFSPF incorporated biscuits on a dry weight basis. Means within a row bearing different superscript letters differ significantly (p < 0.05). T1: WF (100%) or control; T2: WF (90%) + PFSPF (10%); T3: WF (80%) + PFSPF (20%); T4: WF (70%) + PFSPF (30%); T5: WF (60%) + PFSPF (40%); T6: WF (50%) + PFSPF (50%). WF: wheat flour; PFSPF: purple-fleshed sweet potato flour.
