*All data reported on dry basis and represent the mean of four replicates ± standard deviation. Means followed by a different superscript in each column are significantly different (p < 0.05). HPWC: High protein wheat/canna composite flour; LPWC: Low protein wheat/canna composite flour, HPWK: High protein wheat/konjac composite flour; LPWK: Low protein wheat/konjac composite flour. To, Tp, and Tc indicate temperature of onset, midpoint and end of gelatinization, respectively; ΔH (J/g dry starch) - enthalpy of gelatinization
