Abstract

The influence of extrusion conditions on the physicochemical properties of buckwheat-corn extrudate was studied. The following properties were studied: volumetric expansion, water absorption index, water solubility index, density, mechanical strength. The following variable levels were used: humidity 12%, buckwheat content 15, 30, 45, 60 and 100%, cylinder temperature 120°C. Increasing the moisture content of the feedstock resulted in higher extrudate density, lower expansion, higher water absorption rate and lower water solubility index. Higher buckwheat content increases extrudate expansion, water solubility index and water absorption index, but reduces its mechanical strength.
