摘要：

Wheat, maize and potato starches were converted to thermoplastic starch (TPS) with glycerol by extrusion, pelletized at changing the speed of extruder screw and studied for apparent d., true d., total porosity, and sp. pore vol. The TPS pellets were studied for water adsorption from air at 20 degrees C and relative humidity 75.3% for 72 h to det. the adsorption kinetics. The lowest hydrophilicity of TPS was found for the pellets extruded at highest speed of extrusion screw (120 rpm).
