| Summary: | Naturally occurring plant-based gums are being widely used in different industries due to their unique
thickening and gelling potentialities. The research was planned to evaluate the influence of hydrolysis
and modification on rheological and thermal properties of Acacia modesta (Phulai) gum extracts. The
gum was hydrolyzed and modified by different chemical methods including polyacrylamide grafting,
carboxymethylation, acidic and basic hydrolysis to alter the viscosity behavior. The rheological behavior
of selected gum extracts was studied. The change in structure and thermal behavior after processing
was determined by Differential scanning calorimetry (DSC), X-ray diffraction (XRD), Thermogravimetric
analysis (TGA) and Fourier transforms infrared spectroscopy (FTIR). The analysis of DSC and TGA revealed
that the processed gum samples were thermally more stable as compared to pristine counterpart of the
crude gum. The present results of A. modesta would be useful for incorporation in various applications
in the food and pharmaceutical industries. |
