The starch/xylitol blends were extruded in a single extruder.Their properties such as mechanical properties,rheological properties,as well as the effect of components and processing parameters,including the processing time and temperature,on these properties were studied.The activation energy for viscous flow was about 225.1 kJ/mol.The micromophology and crystallinity of the blends have been investigated by scanning electronic microscope and X-ray diffraction method.The result of tests showed that the starch granules were broken and the crystallinity decreased in the blends of starch and xylitol.
