Evaluation of Xanthan/Enzymatically Modified Guar Gum Mixtures in Oil-in-Water Emulsions
… was to evaluate xanthan/enzymatically modified guar (XG/EMG) polysaccharides on the physical and oxidative stability of 2 wt% whey protein stabilized oil-in-water emulsions containing 20% v/v menhaden fish oil. Enzymatic modified guar gum was obtained by hydrolyzing native guar gum using …

Enzymes Involved in the Utilization of the Galactomannan, Guar Gum, by Bacteroides Ovatus
When Bacteroides ovatus is grown on guar gum, a galactomannan, it produces an (alpha)-galactosidase (I) which is different from the (alpha)-galactosidase (II) it produces when it is grown on galactose, melibiose, raffinose or stachyose. I have purified both of these enzymes to apparent homogeneity. …

Development and characterization of edible films made from four dietary fibers -pectin, guar gum, locust bean gum, and hydroxypropyl methylcellulose
… polymer concentration of 4 dietary fibers, e.g., guar gum, locust bean gum, pectin, and hydroxypropyl methylcellulose, and glycerol concentration to the mechanical properties and dissolution/ partial dissolution time of their films and the viscosity of their solution. Specifically, it investigates …

The Effect of Xanthan Gum and Guar Gum on Enhancing the Quality and Preventing Lipid Rancidity in Yeast Bread Supplemented with Flaxseed
This study examined the effects of guar gum and xanthan gum on flax supplemented breads through objective and sensory testing. Breads containing flaxseed and gums were found to have a significantly (p<0.05) higher water activity than the control bread. Control bread was also found to have a higher …

The effect of different sources of dietary fiber on the plasma total and lipoprotein cholesterol, liver cholesterol, fecal neutral steroid excretion and histology of major organ tissues in hamsters
… six groups for another 4 wk: control, oat bran, guar gum, cellulose, xylan and sacrifice. After 4 wk of the fiber diets (10% dietary fiber), the plasma TC levels were significantly lowered in the oat bran, guar gum and xylan groups (16%, 12% and 15%, respectively) (p<.05). They were also …

The effect of exopolymers on the compressibility and shear strength of kaolinite
… methods for using two exopolymer analogues, guar gum and xanthan gum, to change the properties of a pure kaolinite. Changes in the compressibility of biopolymer and kaolinite mixtures were measured using 1D consolidation and triaxial tests. Also, modifications of shear strength were measured …

Modelling of physical and chemical processes in the small intestine
… have shown that the functional ingredient guar gum reduces the mass transfer coefficient of the model nutrient riboflavin. This together with computational modelling suggests an explanation for the observed functionality of guar gum to reduce the peak increase in blood glucose levels after …

Urinary carbohydrates as an indicator of digestion and absorption of dietary fiber in a monogastric animal
… rats were then fed diets containing 5 percent guar gum (a galactomannan), 10 percent xylan (a polymer of xylose), or 10 percent wheat bran. The appearance in the urine of the component carbohydrates of the ingested dietary fiber was used as an indication of the absorption of the carbohydrates …

Mucoadhesive buccal tablets for the delivery of nicotine and Delta9-tetrahydrocannabinol.
… polysaccharide matrix formers including xanthan gum, karaya gum, guar gum and glycol chitosan were investigated for the ability to provide controlled nicotine release and adhesion to animal buccal mucosa. Different release mechanisms were identified in the polysaccharides including anomalous …

Investigating the relative adsorption of polymeric depressants on pure minerals
… and chalcopyrite and the depressants used were guar gum and carboxymethyl cellulose (CMC). It was hypothesised at the beginning of this study that polymeric depressants adsorb preferentially onto different minerals because of the differences in the surface charge of the minerals which arise as a …

Nutritional strategies to control clostridium perfringens in gastrointestinal tract of broiler chickens
… or soy protein concentrate) and soluble fiber (guar gum). Clinical NE was not observed, however, there was a high level of C. perfringen colonization especially in guar gum fed birds. The next set of experiments examined the effect of various levels of DL-Met or MHA-FA on C. perfringen and other …

Impact of ingredient interactions on the physico-chemical stability of milk protein-stabilised oil-in-water emulsions
… phenomena. Using a model system including guar gum in a sodium caseinate stabilised oil-in-water emulsion, it was shown that intermediate concentrations may have the opposite effect: in fact, faster creaming may occur due to depletion flocculation effects when adding a neutral …

Utilization of selected dietary fibers by dogs and cats
… lactulose, citrus pectin, and guar gum. In vitro fiber fermentation with cat fecal microflora indicated least fermentation of Solka Floc$\sp\circler$ while citrus pectin, guar gum, and locust bean gum resulted in greatest fermentation. In vitro results were used to formulate …

Development and optimisation of food products low in FODMAPs: an investigation of dietary fibres in low FODMAP products and the reduction of FODMAPs via bio-technological processes
… and two soluble-viscous DFs (psyllium and guar gum) was tested in bread and pasta. Two different concentrations of these DFs (3 g/ 100g and 6 g/100 g) were used to produce a bread. The application of these DFs in a bread system, highlighted that the effects on the bread quality …

Improving Adhesion of Seasonings to Crackers with Hydrocolloid Solutions
… The hydrocolloids that were used include gellan gum, kappa-carrageenan, methyl cellulose, gum karaya, gum tragacanth, gum arabic, guar gum, modified starch, and maltodextrin. Solutions of similar hydrophobicity to the powder gave the greatest adhesion. NaCl, barbecue (BBQ), ranch, and sour cream …

Guar and locust bean gums as partial replacers of all-purpose flour in bread: an objective and sensory evaluation
… could be partially replaced with locust bean gum (LBG) and guar gum, and produce an acceptable bread product. A pilot study determined that up to 4% gum replacement for flour was feasible. All bread treatments were evaluated objectively by standing height, texture, color, and cell size. …
