PV, peak viscosity; HV, hot viscosity; BV, breakdown viscosity (PV − HV); FV, final viscosity; SV, setback viscosity (FV − HV); PT, pasting temperature. Data are means ± standard deviations, n = 3. Values in the same column and variety with different superscript letters are significantly different (p < 0.05).
