Rheological Properties of Arrowroot Statch Suspension

Abstract
|
|
|
|
The theological properties of arrowroot starch suspension (2-6%) were investigated with a tube viscometer. The starch suspensions of less t¹, 4% showed a dilatant behavior with no yield stress at the temperature range of 30-65℃. However, the starch suspension of 6% concentration showed a pseudoplastic behavior at 65℃. The consistency index was exponentially increased with the increase of the starch concentration. The activation energy of flow of the starch suspensions was 0.370-0.399㎉/mole at 30°-60℃ and 28-60 ㎉/mole at 65℃.
