Xanthan gum is used to stabilize aqueous foams in a wide number of commercial and industrial processes one the numerous hydrosoluble polymers slow foam drainage. The slowing effects viscosity on drainage flow have been well studied but situations leading delay are poorly described literature. aim this study was shed light mechanisms governing initiation. Drainage seems be result liquid retentio...

kefiran, extracted from kefir grains, is a water-soluble, glucogalactan containing almost equal amounts of d-glucose and d-galactose residues. throughout this research, kefiran and xanthan were added at concentrations of 3% (w/w flour basis) to two wheat dough samples to investigate the effects on the rheological and physical properties of french bread. physicochemical properties of wheat and i...

Synergistic hydrogels are often encountered in polysaccharide mixtures widely used in food and biopharma products. The xanthan and konjac glucomannan pair provides one of the most studied synergistic hydrogels. Recently we showed that the junction zones stabilizing the 3D structure of this gel are present as macromolecular complexes in solution formed by the partially depolymerised polysacchari...

Flow and dynamic rheological properties of hot thickened soups for consumption by the elderly people with swallowing difficulty (dysphagia) were investigated at a serving temperature of 60°C. In this study, sea mustard soup (SMS) and dried pollock soup (DPS), which have been widely known as favorable hot soups provided in a domestic hospitals and nursing homes for dysphagic patients, were thick...

AIM The aim of this study is to compare the effectiveness of the ophthalmic gels containing hyaluronate, xanthan gum, and netilmycine with fusidic acid in terms of recovery periods of corneal epithelium in the patients who underwent pterygium surgery. METHODS Patients who underwent pterygium surgery were separated into two groups. Forty patients in group 1 were given eye gel containing sodium...

In this paper we have derived constitutive equations for an elastic material with anisotropic rigid particles. We have included a dependence on the Finger tensor B and the orientation tensor Q in the expression for the free energy of the system. With this expression for the free energy we have derived an expression for the stress tensor up to second order in both these variables. We have shown ...

In this work, the fractional mathematical model of an unsteady rotational flow of Xanthan gum (XG) between two cylinders in the presence of a transverse magnetic field has been studied. This model consists of two fractional parameters α and β representing thermomechanical effects. The Laplace transform is used to obtain the numerical solutions. The fractional parameter influence has been discus...

The question of how to ensure effective administration has greatly plagued the medical and food industries. Whether it’s cancer drugs or nutrient molecules, without stable carriers these compounds become inactive before they reach their destinations. Ensuring successful administration of these drug molecules requires the discovery of substances that can form rigid, protective structures. Xantha...
