ABSTRACT
Study results on the selected physical properties of extrudates obtained from various cereals, legume and oleaginous seeds processed in a twinscrew extruder are reported in the paper. Influence of barothermal process parameters: temperature, pressure, die`s size, screw`s rotational speed on the expansion ratio and the water absorption index of the extru- dates was examined. The results obtained were used to define relationships between extrusion-cooking process parameters and quality of the products received from different raw materials.
