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).

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 ...

Characterization of curcumin incorporated guar gum/orange oil antimicrobial emulsion films.

International Journal of Biological Macromolecules, 2020
Edible films are manufactured from natural, renewable, nontoxic, and biodegradable polymers and are safe alternatives to plastic food packaging. Despite ongoing research, biopolymer-based edible films still are not at a quality to ensure total commercial

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.

Film-forming properties of guar gum, tara gum and locust bean gum

, 2020
Galactomannan films have received great interests due to the sustainability, biodegradability and biocompatibility. Guar gum (GG), tara gum (TG) and locust bean gum (LBG), with a mannose/galactose (M/G) ratio of 2, 3 and 4, respectively, were ...

Thermal degradation of guar gum

Carbohydrate Polymers, 1989
Abstract Information about the thermal degradation of guar gum has been obtained from the time dependence of the viscosity at high temperatures measured using a slit viscometer. The viscosity is related to the molecular weight using previously published relations between the zero shear specific viscosity and the coil overlap parameter in conjunction ...
