BACKGROUND AND AIMS Enteral fiber-free diets alter intestinal transit and produce diarrhea or constipation. This prospective double blind, controlled study evaluates the use of guar gum, a soluble fiber and a candidate prebiotic in enteral feeds, to prevent diarrhea and potential health benefits in intensive care unit patients. METHODS Twenty patients on enteral nutrition with persistent diar...

introduction: cakes are usually formulated including wheat flour, sugar, egg and some liquids such as milk, water and oil. the textural properties of gluten in dough such as tensile, expansion and tolerance capability during mixing are major factors in baking industry. in fact, the structural protein to produce bread, cakes, muffins and biscuits is called gluten and the absence of gluten due to...

The production of α-galactosidase from the wild fungal strain Aspergillus foetidus MTCC 6322 using solid state fermentation (SSF), its characterization, and its efficacy in the hydrolysis of soymilk using response surface methodology were studied. The optimum conditions for production of α-galactosidase by SSF were: wheat bran (10 g), moisture content (64%), inoculum volume (1.0 mL; 6 x 10(7) s...

Aspergillus terreus FBCC 1369 was grown in solid-state culture under statistically optimized conditions. β-Mannanase was purified to apparent homogeneity by ultrafiltration, anion exchange and gel filtration chromatography. A purification factor of 10.3-fold was achieved, with the purified enzyme exhibiting specific activity of 53 U/mg protein. The purified β-mannanase was optimally active at p...

PURPOSE The purpose of this study was to develop and evaluate metronidazole loaded floating-mucoadhesive microsphere for sustained drug release at the gastric mucosa. METHODS Alginate gastroretentive microspheres containing metronidazole were prepared by ionic gelation method using sodium bicarbonate as gas forming agent, guar gum as mucoadhesive polymer, and Eudragit L100 as drug release mod...

BACKGROUND: The present study focuses on the design and evaluation of colon targeted matrix tablets of Mebeverine hydrochloride using natural gums like guar gum, xanthan gum at different concentrations. This novel approach is expected to be promising drug delivery system for delivering Mebeverine HCl to the colon for its local action and thereby minimizing systemic side effects of the drug. MET...

The purpose of this research was to develop gastro-retentive delivery system of atenolol which, after oral administration should have the ability to prolong gastric residence time with desired in vitro release profile. Atenolol was chosen as a model drug because it is poorly absorbed from the lower gastrointestinal tract. The tablets were prepared by direct compression technique, using natural ...

Four pigs initially of 30 kg live weight were surgically prepared with two re-entrant cannulas in the jejunum 1.0 m apart which allowed an isolated loop to be formed through which solutions were perfused. 51Cr-EDTA was used as a marker for measuring net secretion or absorption. A new Ringer solution was made, the ionic content of which resembled more closely that found in the jejunum of pigs gi...

This paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including Iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). The basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. Viscosity measurements were al...

Introduction: Dietary fiber is an important component of human diet. Since each fiber type has specific metabolic and gastrointestinal function effects, in each specific pathology we will have to choose the optimum type of fiber, considering its chemical, physical and physiological properties. Objective:to put partially hydrolyzed guar gum in its place in the complex framework of dietary fiber...
