Title

THE EFFECTS OF SODIUM AND CALCIUM CHLORIDE SALTS ON THE CHARACTERISTICS OF BASIL SEED GUM

Pages

  75-82

Abstract

 Introduction: HYDROCOLLOIDs or gums are defined as macromolecules that could dissolve or disperse in water and give viscous solutions or gels. In this study, the effect of salts at different concentrations on the rheological properties of Basil seed gum solution was studied.Materials and Methods: The effects of sodium and CALCIUM CHLORIDE at concentrations of 0.1, 0.25, 0.5 and 1% on the rheological properties of Basil seed gum solution (0.2%) were investigated. Rheological properties of solutions were measured by a Brookfield rotational viscometer.Results: In all solutions, with increasing shear rate, the apparent VISCOSITY decreased, indicating the pseudoplastic behavior of Basil seed gum. Interactions between gum and salts decreased the VISCOSITY of solutions and the amount of VISCOSITY change depends on the type of salt. Apparent VISCOSITY is clearly decreased from 8.1 to 1.9 mPa.s with increasing SODIUM CHLORIDE concentration from 0.1 to 1 % (shear rate=61.2 s-1).Conclusion: Power law model well described the non-Newtonian behavior of Basil seed gum in the presence of salts. Fitting with this model showed that the consistency coefficient (k) and flow behavior index (n) were influenced by the type and the concentration of salts content. Addition of sodium and CALCIUM CHLORIDE led to increases in flow behavior index and decreases in pseudoplastic properties of the solutions.
