Ferula gummosa Boiss. (Apiaceae) is one of the natural plants of Iran. The whole plant, but especially the root, contains the gum resin "galbanum". A study of the comparative effects of galbanum gum and two standard binding agents--polyvinylpyrolidone and acacia--on characteristics of acetaminophen and calcium carbonate compacts was made. The Ferula gummosa gum was extracted and its swelling in...

Xanthan gum, a complex polysaccharide comprising glucose, mannose and glucuronic acid residues, is involved in numerous biotechnological applications in cosmetics, agriculture, pharmaceuticals, food and petroleum industries. Additionally, its oligosaccharides were shown to possess antimicrobial, antioxidant, and few other properties. Yet, despite its extensive usage, little is known about xanth...

Overdose of acetaminophen, a widely used analgesic drug, can result in severe hepatotoxicity and is often fatal. This study was undertaken to examine the effects of arabic gum (AG), which is commonly used in processed foods, on acetaminophen-induced hepatotoxicity in mice. Mice were given arabic gum orally (100 g l(-1)) 5 days before a hepatotoxic dose of acetaminophen (500 mg kg(-1)) intraperi...

the effect of xanthan and qodume shirazi seed gum on fresh bread quality and its influence on dough rheology were studied. incorporation of 0.3 to 1% of these two gums was investigated to evaluate its effect on the mixing tolerance index (mti), dough development time (ddt), gelatinization temperature (gt), viscosity, dough stability and quality of wheat flour. addition of xanthan and qodume shi...

The recent focus on the potential link between periodontal and cardiovascular disease (PD and CVD) is part of the larger renewed interest on the role of infection and inflammation in the etiology of atherosclerosis and its clinical manifestations. Periodontal Disease is an inflammatory process affecting the periodontium, the tissue that surrounds and supports the teeth. The process usually star...

In this study the rheological and textural properties of Iranian white cheese produced by ultrafiltration technique containing gum tragacanth and xanthan gum each in the range of 0-0.1%, and basil seed and linseed mucilages each in the range of 0-0.2% were evaluated. According to the results obtained, values of Elastic (G/) and viscous (G//) moduli increased with increasing frequency sweep in a...

We report the draft genome sequence of Sphingomonas sp. WG, a high welan gum-producing strain with a yield of 33 g/L. The core of wel cluster for welan gum biosynthesis contained 24 coding sequences in the genome, which will provide the genetic information on welan gum production.

Gum polysaccharides are comprised of different monosaccharide units joined together by O-glycosidic linkages. The structural diversity of different polysaccharides is due to differences in degree of polymerization, monosaccharide composition, chain shapes, and linkage types. Gum polysaccharides are commonly used in both food and nonfood industries as stabilizers, thickening and gelling agents, ...

objective: the use of sugar-free chewing gums has been reported to be highly effective in the prevention of dental caries. this study carried out to compare the effect of mastic gum and a xylitol chewing gum on remineralization of caries-like lesions. materials and methods: in this cross-over, single blinded, in situ study, first, artificial caries-like lesions were created in six extracted hum...
