Fluoroacetic acid in guar gum

Food and Chemical Toxicology, 1984
The toxicity of guar gum, derived from the Indian leguminous plant Cyamopsis tetragonolobus, is thought to be due to a globulin which can be denaturated and made non-toxic. Another very toxic compound, fluoroacetic acid, has been detected at a low level in raw samples of guar gum (0.07-1.42 micrograms fluoroacetic acid/g).

Carbamoylethylation of guar gum

Carbohydrate Polymers, 2004
Carbamoylethylation of guar gum was carried out with acrylamide in presence of sodium hydroxide under different reaction conditions. Variables studied were concentration of sodium hydroxide, acrylamide, guar gum as well as reaction temperature and time. The nitrogen content, carboxyl content and total ether content were determined.

Viscosity of guar gum and xanthan/guar gum mixture solutions

Journal of the Science of Food and Agriculture, 2000
The viscosity of diluted guar gum solutions and the viscosity of xanthan and guar gum mixture solutions have been studied. Guar gum solutions showed pseudoplastic behaviour. Apparent viscosity increased with gum concentration and decreased with the temperature at which viscosity was measured.

Occupational asthma caused by guar gum

Journal of Allergy and Clinical Immunology, 1990
Some vegetable gums have been reported to cause asthma. We describe three subjects who were exposed at work to guar gum, which is derived from the outer part of Cyanopsis tetragonolobus, a vegetable that grows in India. The first subject worked for a pharmaceutical company; the second and third subjects worked at a carpet-manufacturing plant. All three

Guar Gum-Based Sustained Release Diltiazem

Pharmaceutical Research, 1998
This study was performed to examine the use of guar gum to sustain the release of diltiazem under in vitro and in vivo conditions.Guar gum tablet formulations were prepared and evaluated under a variety of in vitro dissolution conditions. The formulations, along with Dilacor XR, were administered to a group eight fasted, healthy volunteers in a four ...

Occupational allergic rhinitis from guar gum

Clinical & Experimental Allergy, 1988
SummaryThree cases of allergic rhinitis from a vegetable gum, guar gum, have been detected. Two subjects were exposed to fine guar gum powder (Emco Gum 563, Meyhall Chemical AG, Switzerland), an insulator in rubber cables, when opening cables in a power cable laboratory. After 1–2 years’ exposure the patients developed rhinitis.

Rheological properties of guar gum and hydroxyethyl guar gum in aqueous solution

International Journal of Biological Macromolecules, 1987
Abstract The rheological properties of aqueous solutions of guar gum (GG) and hydroxyethyl guar gum (HEG) have been investigated. The flow properties of these polysaccharide solutions were studied at the shear rate in the range 1.5–1310s−1 using a Rheotest-2 viscometer.
