Abstract:
To clarify the effects of extruded buckwheat on the dough properties and noodle quality of buckwheat-wheat flour, the solvent retention capacity (SRC), gelatinization, thermo-mechanical properties, cooking characteristics, texture characteristics were comprehensively studied. The results showed that sucrose, sodium carbonate and lactic acid SRC significantly increased with the addition of buckwheat flour (
P<0.05). However, peak viscosity, minimum viscosity, breakdown value, final viscosity and setback value decreased significantly (
P<0.05). The water absorption, weakening degree C
