ABED EL KADER, D et al. Analytical characterization of five Venezuelan Mimosaceae gums which have a possible industrial applications. Rev. Fac. Agron. [online]. 2002, vol.19, n.3, pp.230-239. ISSN 0378-7818.

Acacia glomerosa, Acacia tortuosa, Acacia macracantha, Samanea saman and Enterolobium cyclocarpum, Venezuelan Mimosaceae species, are able to exudate gum, after appropriate stimulation. Data on these gums, determined by classical analytical methods, are very interesting. Acacia tortuosa and Acacia macracantha gums are very soluble, in water; Enterolobium cyclocarpum and Samanea saman gums showed high intrinsic viscosity. Sugar composition of the gums studied showed them to contain galactose, arabinose, rhamnose, glucuronic acid and its 4-0-methyl derivative. The data obtained showed some similarities with that reported for Acacia senegal gum, which has wide industrial application; therefore, it would be very interesting to test the behavior of those gums in the food industry and other industrial applications.
