Abstract
The rheology of starch-DMSO-water solutions was studied as a function of wa ter content and temperature. A correlation between flow regime, temperature , and water content was presented so as to characterize amylose conformatio n change in a novel way. Rheological behavior was characterized using an em pirical equation to classify fluids under study as Newtonian, pseudoplastic , or dilatant. The temperature effect was analyzed through the determinatio n of the apparent activation energy and preexponential constant. (C) 2001 J ohn Wiley & Sons, Inc.
