Using dynamic rheometer to study fluidization characteristics of complex japonica rice-kudzu powder rice which were made by twin-screw extruder. Research indicated: rice made by twin-screw extruder had the characteristic of high degree of paste. Temperature scan in cooling process after secondary pasting indicates extrusion rice was not easy to regenerate. Adding kudzu powder could further improve anti-regenerative ability of extrusion rice. With 12% rat...
