쌀보리와 겉보리전분의 희석 및 농후호화용액에 대한 리올로지적 성질을 여러 점도계를 사용하여 연구하였다. 희석전분액(0.05
The rheological studies on dilute and concentrate solutions of naked and covered barley starches were carried out with various viscosimeters. The rheology of dilute solutions (0.05-0.3%) were characterized by intrinsic viscosity and related parameter according to Huggins equation. Also, the rheology of the solutions of higher concentrations (1-5%) were characterized by time dependent characteristics and pseudoplastic behaviors. The values of consistency index according to the power equation were exponen tially dependent upon concentration and temperature. The results showed that the rheological properties could differ greatly due to difference in varieties. The naked barley starch exhibited higher intrinsic viscosity, more thixotropic behavior and more dependence of consistency index on concentration and temperature than the covered barley starch.
