Background and Objectives: The quality of cakes made of wheat flour depends on the quantity and quality of its gluten proteins however, these proteins may have side effects for some people, including the patients with celiac, and the only way to cure this disease is to take a lifelong gluten-free diet. Materials and Methods: This research aims to produce gluten- free cake by using rice flour a...

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...

Th e pasting behavior of native Water Chestnut Starch – hydrocolloids mixtures was studied. Th e eff ect of Xanthan, Guar, Carboxy Methyl Cellulose and Acacia on Water Chestnut Starch was examined by using micro Viscoamylograph. It was noticed that all hydrocolloids greatly modify the pasting properties of water chestnut starch. Results showed that gelatinization temperature of water chestnut s...

We experimentally investigate the filament dynamics of non-Newtonian drops falling under gravity through air, and report the effects of semiilute concentrations of the polyelectrolyte polymer xanthan gum mixed in 80:20 glycerol/water with varying concentrations of potassium chloride KCl). We find that the addition of 780 ppm xanthan gum to the glycerol/water solvent dramatically increases the d...

Voriconazole is a novel antifungal agent with excellent broad spectrum activity commercially available for oral and intravenous administration. The purpose of this study was to prepare ophthalmic formulation of hydroxypropyl beta cyclodextrin (HP-β-CD) based voriconazole containing benzalkonium chloride BAK and EDTA with or without viscosity modifiers and study its permeation characteristics th...

in this research, after conducting chemical tests on flour samples (moisture, ash, protein, fiber and ph), potato flour and xanthan gum were added to wheat four at levels 5, 10 and 15 percents and 0.5 and 1 percents, respectively, and subsequently production of toast bread in semi-industrial manner was started, then the qualitative characteristics (nutritional value) of toast breads were measur...

BACKGROUND AND OBJECTIVE The genus Xanthomonas is composed of phytopathogenic bacterial species. In addition to causing crops diseases, most of the Xanthomonas species especially Xanthomonas campestris produce xanthan gum via an aerobic fermentation process. Xanthan gum is, an important exopolysaccharide from Xanthomonas campestris, mainly used in the food, petroleum and other industries. the p...

The aim of this study was to investigate the influence of pH, buffer species and ionic strength on the release mechanism of chlorpheniramine maleate (CPM) from matrix tablets containing chitosan and xanthan gum prepared by a hot-melt extrusion process. Drug release from hot-melt extruded (HME) tablets containing either chitosan or xanthan gum was pH and buffer species dependent and the release ...

Sensory parameters of gluten-free bread depend on the amount and type of hydrocolloids used as gluten replacers, as this determines interactions between them and starch, which is the main component of dough. The evaluation of gluten-free breads supplemented with various amounts of guar gum, pectin and xanthan, proved that bread with addition of xanthan has higher volume in comparison with pecti...

   Prolonged residence of drug formulation in the nasal cavity is important for the enhancing intranasal drug delivery. The objective of the present study was to develop a mucoadhesive in-situ gelling nasal insert which would enable the reduced nasal mucociliary clearance in order to improve the bioavailability of metoclopramide hydrochloride. Metoclopramide hydrochloride is a potent antiemetic...
