Abstract The effect of drying methods on the rheological properties (apparent viscosity, storage (G′) and loss (G″) moduli, creep behavior) of sugar beet pulp pectin (SBPP) was investigated using steady shear, frequency sweep, activation energy and creep-recovery tests. SBPP was extracted from sugar beet and dried using freeze (FD), hot air (HD), vacuum (VD) and spray (SD) drying methods. The HD sample showed highest apparent viscosity and the VD sample had the highest activation energy. The 1 % (w/v) samples had higher activation energy than 2 % (w/v) samples. The G′ and G″ versus angular frequency data followed the Power Law model reasonably well (R2 > 0.915). The FD sample deformed the most during the creep test.
