Abstract :
Rheological methods were applied to study the effect of sweeteners on the intrinsic viscosity of salep in dilute solutions. The concentration of these sweeteners were 0.1, 0.2% w/v for Aspartame, Acesulfame-K and Cyclamate, 0.001, 0.002% w/v for Neotame. Gum was evaluated for intrinsic viscosity by various models i.e. Huggins, Kraemer, Tanglertpaibul and Rao equations. The results showed that the values obtained for intrinsic viscosity were different upon various equations used. The plot of relative viscosity versus gum concentration obtained from Tanglertpaibul and Rao model was found as best model. Synthetic sweeteners in these rages of concentration had no significant effect on intrinsic viscosity of salep gum in solutions.
