Food composition and properties

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 μg fluoroacetic acid/g). A sample of a guar-gum pharmaceutical formulation contained only 0.08 ppm fluoroacetate. One exceptionally high value of 9.5μg/g was found in a guar-gum powder. The low concentrations of fluoroacetate found in guar gum dispel any considerations about possible health risks associated with fluoroacetate during the prolonged use of guar gum at the recommended doses.
