Ten, twenty and thirty percent (g/100 g) of wheat flour was substituted with partially gelatinized corn
starch or ungelatinized corn starch and the rheological properties of the resultant dough samples were
investigated. The apparent viscosity of dough increased with the increase in the concentration and
degree of gelatinization of partially gelatinized starch samples except in the case of dough substituted
with starch sample with high gelatinization degree (96.78%) at 30 g/100 g concentration. The presence of
partially gelatinized starch increased the storage (G0) and loss (G00) moduli values and decreased the
frequency sensitivity of dough samples. The dough prepared from wheat flour alone (control) showed
the highest creep compliance and the lowest elastic recovery. In brief, the rheological properties of dough
were influenced by the degree of substitution more than by the degree of gelatinization of substitutes.
