Rheological properties of waxy barley flour (WBF) dispersions mixed with various gums (carboxyl methyl celluleose, guar gum, gum arabic, konjac gum, locust bean gum, tara gum, and xanthan gum) at different gum concentrations were examined in steady and dynamic shear. WBF-gum mixture samples showed a clear trend of shear-thinning behavior and had a non-Newtonian nature with yield stress. Rheolog...

Oral dissolvable films (ODFs) of diclofenac sodium intended for osteoarthritis were prepared using Albizia and Khaya gums as hydrophilic film formers. The physicochemical properties of the gums were characterized and the gums were used to prepare diclofenac sodium ODFs (~50 mg/4 cm(2) film) by solvent casting. The two gums showed satisfactory film forming properties. The physicomechanical prope...

BACKGROUND Oesophageal acid neutralization with antacids depends on the duration of oesophageal antacid exposure and acid neutralizing capacity. A gum that releases antacid as it is chewed could take advantage of both mechanisms to enhance heartburn relief. METHODS Twenty-four subjects were crossed over to four regimens: placebo, chewable antacid tablets (1000 mg CaCO3), lower dose gum (600 m...

BACKGROUND Extrinsic staining of teeth may result from the deposition of a variety of pigments into or onto the tooth surface, which originate mainly from diet or from tobacco use. More recently, clinical studies have demonstrated the efficacy of some chewing gums in removing extrinsic tooth staining. The aim of this study was to assess the effectiveness of two nicotine medicated chewing gums (...

regarding outbreak of coeliac in some parts of the world, production of free-gluten cakes is increasing worldwide. rices is often advised for people suffering from coeliac. in this research, the effect of adding xanthan and carboxy methyl celloulose gums on qualitative, sensory and staling properties of rice cakes was studied. the said gums were added at two concentrations of 0.25% and 0.75% an...
