kefiran is an exogenous microbial metabolite produced mainly by bacteria and fungi during growth. the present study investigated the effects of the addition of 3% kefiran and 3% xanthan on the extensographic characteristics of wheat dough and the shelf life of raised bread. kefir grain was cultivated in a shaking incubator and kefiran extraction was carried using a centrifugal refrigerator. the...

The effects of different hydrocolloids on the gelatinisation behaviour of hard wheat flour were investigated. Influence of guar, xanthan, Arabic, carboxy methyl cellulose (CMC) and tragacanth gums on wheat flour was studied using micro viscoamylograph. It was found that all hydrocolloids except tragacanth greatly modified the gelatinisation properties of wheat flour. Guar and xanthan significan...

saturated fat consumption increases the risk of both coronary and cancer diseases. therefore, fat reduction in uf-feta cheese (≈ 45% fdm) is favorable but, unfortunately, it has some negative effects on the texture and sensory characteristics of the cheese. in this research, response surface methodology was employed to study the probably improving effects of wpc80 (0-20 gr kg-1), lecithin (0-2 ...

background and objectives: the effect of the different proteins and polysaccharides on the characteristics of low-fat cheese has been a topic of recent study. the release of aromatic compounds from the cheese is affected by the addition of texture improvers. the present study investigated the addition of polysaccharides and proteins on the hardness, microstructure and ester release of low-fat b...

Blended cornstarch–xanthan gum systems were optimized for thickening of cocoa syrups. For this purpose the sensory (whole and partial), textural (force of penetration, adhesiveness and stringiness) and rheological properties (flow curves as well as viscosity/time and viscosity/temperature relationships) of cocoa syrups were studied. Flow curves were described by rheological model of Casson, whi...

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 an...

The effect of food matrix rheology and fat content on thermal inactivation Listeria monocytogenes in the Shaka agitated retort (final temperatures 59, 64, 69 °C) was investigated using four fish-based artificial model systems: low-viscosity liquid (liquid), high-viscosity (xanthan), emulsions containing 10% 20% (emulsion emulsion 20%). Model system rheology, quantified by consistency index K fl...

The aim of this study was to investigate the influence of pH, buffer species and ionic strength on the release mechanism of Glipizide (G) from matrix tablets containing chitosan and xanthan gum prepared by a hot-melt extrusion process. The release mechanisms were controlled by the solubility and ionic properties of the polymers. All directly compressed (DC) tablets prepared in this study also e...
