Abstract:

In the present investigation, rheological properties (viscosity) of different gum like Karaya, Babool, Anogiessus latifolia, Acacia nelotica and Acacia Senegal were found by Brookfield viscometer and compare its swelling capacity. Mucilages containing 1 to 10% w/v of different gum were prepared by dispersing in freshly distilled water and allowed to stand undisturbed for 24 h for complete hydration. The viscosity and shear stress were recorded at different speeds, ranging from 0.5 to 100 rpm at room temperature (28-30°C). The viscosity of gums increases with the increased in the concentration (1 to 5%) in the entire gum specimen (Acacia Senegal, Anogiessus latifolia, Acacia nelotica and Sterculia urens Roxb.). In Acacia Senegal, Anogiessus latifolia and Acacia nelotica gum, variation in viscosity with shear rate is very less i.e. nearly constant and exhibited a Newtonian behaviour. In Karaya gum, viscosity decreased with the increased in shear rate and exhibited pseudoplastic (shear thinning) behaviour. Karaya gum has higher capacity to form viscous solutions and gels at low concentration as compare to Acacia Senegal, Anogiessus latifolia, Acacia nelotica gum.
