| Abstract: | Objective]The cassava starch was activated with home-made high efficiency stirring mill. The research was to study the effect of mechanical activation on the powder integrative character of cassava starch. Method]Powder integrative characters of cassava starch activated for different times were detected with BT-1000 powder integrative characteristic tester. Result]Angle of repose,collapse angle,flat plate angle and Carr's index decreased,but the different angle,the dispersity and the voidage increased,wi... |
