Enhancement of Thermal Sealing and Solubility Properties of Konjac-Glucan/Gelatin Films by Hydroxypropyl Cassava Starch Thermoplastic Effect

) exhibited superior mechanical properties (tensile strength (TS): 17.54 MPa) and excellent barrier performance against both light and oxygen transmission compared to pristine KGM and KG control films. Self-sealed pouches fabricated from KGH films preserved edible oil for 65 days, maintaining peroxide values within acceptable limits and demonstrating 48.7% reduction in oxidation compared to KG films. These findings establish KGM-Gel-HS film as promising candidates for adhesive-free, biodegradable packaging of lipid-rich foods.
