Gum Arabic


a hard, transparent substance secreted by various species of acacia; a viscous fluid that hardens in air and dissolves in water, forming a gluey, slightly acidic solution. Gum arabic was formerly used in many branches of industry as an adhesive, but it is losing its importance increasingly with the development of polymer production.

In total reflection mode, the most significant region of the MIR spectra (Figure 5(a)) corresponds to the C-O vibrations: both the polysaccharides display indeed an intense and narrow band maximum at 1171 [cm.sup.-1], followed with decreasing intensity by well-defined peak maxima positioned at 1144 and 1100 [cm.sup.-1] in cellulose and at 1108 in Arabic gum. The lineshape of all these combined bands is characterized by a very steep slope, thus resulting in sharp absorptions after the application of the KK logarithm.
