Effect of Irradiated Gum Tragacanth on Rheological Properties of Oil in Water Emulsion
Background: Emulsions are thermodynamically unstable systems that can be kinetically stable by adding substances known as emulsifiers and/or thickening agents. By respect to the functional properties of gum tragacanth (GT), and its breakage probability during irradiation treatment, the major aim of this study was to investigate the stability of oil in water emulsion in the presence of different...
متن کاملAn investigation on injectable composites fabricated by 45S5 bioactive glass and gum tragacanth: Rheological properties and in vitro behavior
The injectable composites were formulated from melt-derived 45S5 bioactive glass powder and gum tragacanth. The effect of tragacanth concentration (2 and 4 w/v%) and powder to liquid ratio (P/L= 1.5 to 2.5) on rheological properties, injectability, degradation, swelling, and bioactivity the composites was studied. With the increase of P/L ratio and tragacanth concentration, the force requ...
متن کاملStabilization Mechanism of Colloidal Suspensions by Gum Tragacanth: The Influence of pH on Stability
An acidic polyelectrolyte, gum tragacanth (GT) , was found to stabilize polystyrene latex particles due to a steric stabilization mechanism. The stability depends significantly on the pH of the solution. To elucidate the stabilization mechanism, a number of parameters, such as the adsorption isotherm, the zeta potential, and the conformation were measured as a function of pH. The adsorption iso...
متن کاملEffect of gum tragacanth on rheological and physical properties of a flavored milk drink made with date syrup.
Date syrup as a nutritional additive and safe alternative to added sugar is one of the best choices for milk flavoring. In this study, a flavored milk beverage was formulated using date syrup for flavoring the product and gum tragacanth to obtain an acceptable mouth feel. Steady shear and dynamic oscillatory rheological properties of the samples contained 3 concentrations (0, 0.1, 0.2, and 0.3%...

متن کاملThe Influence of Various Silicones on the Rheological Parameters of AZG Containing Silicone-Based Gels
Aluminium zirconium tetrachlorohydrex glycine (AZG) is a popular antiperspirant/deodorant agent, formulated in various forms including the clear gels. Silicones are used for the preparation of these gels, giving them desirable characteristics. The aim of this study was to investigate the influence of various silicones, when used in combination, on the rheological properties of the resulting AZG...
