Abstract:
Rohina (Soymida febrifuga) and Goinja (Lannea coromandelica) biopolymers (gum exudates) was extracted from naturally growing trees species from forest areas of Chhattisgarh through tapping techniques, using gum enhancers (Ethephon) and collected gum was purified. The purified gum exudates of Rohina and Goinja, was physico-chemically analyzed. The protein, Fiber, pH, Swelling index, moisture content and Tannin content were found to be ranging from 1.15 to 1.29, 87.41 to 82.03, 6.29 to 5.64, 3.53 to 5.33, 9.52 to 9.47 and 1.07 to 0.68 respectively. The SEM analysis of both species, gums revealed a typical trend of particle shape/structure indicated the amorphous nature. Goinja (L. coromandelica) gum water absorption capcity higher (swelling index) compared to Rohina gum because of their particle shape. DSC and TGA thermograms were characteristic of each gum. The thermogram showing the exothermic peak at round 130°C in of Goinja (Lannea coromandelica) and Rohina (Soymida febrifuga) it observed at 33°C. Goinja (Lannea coromandelica) gum show more stable as compared to Rohina gum.
