Deep eutectic solvent plasticization of chitosan/distiller's grains prolamin films: Hydrogen bond-driven structural regulation and enhanced food preservation performance.
Developing sustainable, high-performance hydrocolloid packaging remains challenging because polysaccharide films are typically brittle and provide limited barrier protection. Here, we present a synergistic strategy combining distiller's grains prolamin (DGSP) and deep eutectic solvents (DES) to tailor the structure and...
