Values are means ± S.D. (n = 2). Values having identical lettering in each column are nonsignificant at .T0 = 100% straight-grade wheat powder chapatis (control), T1 = 2.5% processed potato powder (PP), T2 = 5% processed PP, T3 = 7.5% processed PP, and T4 = 10% processed PP. †Nitrogen-free extract = 100–(moisture + ash + fat + fiber + protein).
