Physicochemical, functional and rheological investigation of Soymida febrifuga exudate gum.

Acacia gum is a well-known and most used exudate gum. High solubility with low viscosity is one of the best property of this gum. Many studies were conducted to find out a substitute for acacia gum but very few gum had shown properties as good as acacia gum. The exudates collected from Soymida febrifuga also shows high solubility with low viscosity as acacia gum. Purified Soymida febrifuga gum (SFG) was characterised for physicochemical, functional, rheological and thermal properties. The FTIR spectra of SFG revealed a typical trend of polysaccharides. The monosaccharide composition of the gums indicated the presence arabinose, galactose, and ribose. Element composition of SFG shows resemblance with AG. However, the molecular weight of SFG is less than the AG. The rheological outcome was derived from flow curve measurements of gum at different concentrations and temperatures. Alikeness was observed in Viscosity profile of both the gums. SFG shows semblance with AG and can be use in food and pharmaceutical industry.
