Rheological interaction of sage seed gum with xanthan in dilute solution

چکیده
Polysaccharide-polysaccharide interactions are attractive in the food, polymer and pharmaceutical systems because they may impart novel or improved functional properties to products and reduce costs. In this work, the rheological interaction of sage seed gum (SSG) as a novel hydrocolloid with xanthan gum (XG) was studied in the dilute region. The intrinsic viscosity of the XG-SSG mixture at five blending ratios (100:0, 75:25, 50:50, 25:75, 0:100) and three temperatures (25, 40 & 55°C) was determined. Antagonistic interaction between sage seed gum and xanthan gum was occurred at 25°C and 40°C, while synergistic interaction was observed for all XG-SSG blends at 55°C.

Rheological study of xanthan and locust bean gum interaction in dilute solution: Effect of salt
An oscillatory capillary rheometer was used to investigate the effects of NaCl, KCl, and CaCl2 on visco-elastic properties of xanthan and locust bean gum (LBG) blends in dilute solution. Gums were evaluated for intrinsic viscosity and elastic component. Molecular conformation of the xanthan–LBG complex was assessed by the power-law and Huggins equations. Addition of any of the three salts reduc...

The aim of this study was to determine the rheological properties of sponge cake batters andphysical (volume, density, moisture content, weight after baking and color) and sensory properties of spongecake formulated with four different levels of wild sage seed gum (0, 0.5, 0.75 and 1.0 %). Sponge cake battersformulated with gums showed pseudoplastic (shear-thinning) and thixotropic (time-depend...
متن کاملInfluence of deacetylation on the rheological properties of xanthan-guar interactions in dilute aqueous solutions.
An oscillating capillary rheometer was used to investigate the effects of xanthan deacetylation on the viscoelastic properties and intrinsic viscosity of xanthan and guar mixtures in dilute aqueous solutions. Deacetylated xanthan exhibited a stronger synergistic interaction with guar than native xanthan did due to the destabilized helical structure and increased chain flexibility of the deacety...

An oscillating capillary rheometer was used to investigate the dynamic viscoelastic and intrinsic viscosity properties of deacetylated xanthan (0.025%), native xanthan (0.025%), guar gum (0.075%), and xanthan–guar mixtures in dilute solutions. Influence of ionic strength on xanthan conformation and interaction with guar gum was elaborated. As the salt concentration increased, a significant (P <...
