Abstract:
Gum ghatti, a plant exudate and versatile hydrocolloid, was exposed to gamma irradiation at doses of 5, 10, and 15 kGy. The effects on its proximate composition, reducing sugar content, structural, rheological, and functional properties were systematically evaluated. Functional characteristics such as water absorption capacity (WAC) decreased, whereas oil absorption capacity (OAC) increased after irradiation. Emulsion stability improved at 10 kGy but declined at 15 kGy due to excessive structural disruption. Viscosity and molecular weight analysis indicated a dose-dependent reduction, with partial crosslinking observed at 10 kGy. SEM and XRD analyses revealed progressive surface fragmentation and molecular rearrangement with increasing radiation dose. FTIR and thermal analyses confirmed corresponding modifications in chemical bonding and thermal stability. These findings demonstrate that controlled gamma irradiation can effectively tailor the structure and functionality of gum ghatti, enhancing its potential for use in food, pharmaceutical, and industrial applications through precise modification of its molecular architecture.
