칡 전분현탄액$(2{sim}6%)$의 리올로지 특성을 $30^{circ}{sim}65^{circ}C$의 온도 범위에서 모세관 점도계를 이용하여 조사하였다. 4%농도의 경우 $65^{circ}C$에서 의가소성 유체의 거동을보였다. 점조도지수 값은 전분 농도의 중가에 따라 지수 함수적으로 증가하였다. 온도 $30^{circ}{sim}60^{circ}C$ 의 경우 전분현탄액의 유동의 활성화에너지는 $0.307{sim}0.399kcal/mole$이었으나, $60^{circ}{sim}65^{circ}C$의 경우에는 약 $28{sim}60kcal/mole$이었다.
The rheological properties of arrowroot starch suspension (2-6%) were investigated with a tube viscometer. The starch suspensions of less $t^1$, 4% showed a dilatant behavior with no yield stress at the temperature range of $30-65^{circ}C$. However, the starch suspension of 6% concentration showed a pseudoplastic behavior at $65^{circ}C$. 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 kcal/mole at $30^{circ}-60^{circ}C$ and 28-60 kcal/mole at $65^{circ}C$.
