摘要: Abstract Normal corn flour and starch were extrusion-cooked at different die L/D ratios (extrusion pressure), screw speeds moisture contents. Apparent viscosity, shear rate, expansion volume molecular degradation of during or after extrusion-cooking determined the interrelationships among these properties studied. Overall, apparent viscosity affected more than did extrusion pressure. The maximum 13.8 for was obtained an 3 kPa-s.
