title: Physicochemical, thermal and functional properties of gamma irradiated chickpea starch.
abstract: The study was conducted to evaluate the effect of gamma irradiation (0, 0.5, 1, 2.5, 5 and 10kGy) on physicochemical, functional and thermal properties of chickpea starch. Results revealed that the pasting properties showed a significant (p≤0.05) decrease in peak viscosity, final viscosity, setback viscosity, trough viscosity and pasting temperature in dose dependent manner. Swelling, solubility index, oil absorption capacity and water absorption capacity increased significantly with dose, while as syneresis decreased with dose. Gelatinization temperatures To, Tpand Tcdecreased significantly with dose. X-ray diffraction showed a characteristic C type pattern of the starches and the crystallinity decreased with dose. Scanning electron microscopy revealed small oval shaped starch granules and slight surface fissures were seen in the irradiated starch treated with 5 and 10kGy.
