Effect of varying concentration and shear rate on viscosity of aqueous guar gum

摘要

Effect of different concentration and varying shear rate on viscosity of guar gum was investigated. The concentration of guar gum of cultivar RGC-986 utilized were 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 per cent w/v. Guar gum solution of various concentration were evaluated for viscosity measurement by Roto-viscometer (RV-20) using MV-II spindle shear rate of 4.51 to 451.00 Sec. at 37 ± 1°C temperature. The result obtain of viscosity were showed increased trends as concentration of guar gum solution increase. When shear rate was increased, viscosity of guar gum solutions was decreased.
