摘要： The growing emphasis on environmental protection has driven the development of green and safe food packaging materials. This study aimed to develop a novel nanocellulose-protein composite film and evaluate its potential applications. Cellulose nanocrystals (CNC) derived from sweet potato leaves were prepared via acid hydrolysis and ultrasonic post-processing. The CNC produced under optimal conditions (60 min of ultrasound treatment at 400 W) had an average particle size of 191.4 +/- 15.6 nm, an average potential of-26.7 +/- 7.2 mV, and a high degree of crystallinity (51.31%). The resulting CNC was subsequently incorporated into peanut protein isolate (PPI) for modification. The results showed that adding 1% CNC significantly improved the tensile strength, barrier properties, water resistance, surface hydrophobicity, and thermal stability of the films. The CNC-PPI films effectively delayed the degradation of strawberry quality during storage. Molecular dynamics (MD) simulations and independent gradient model (IGM) analysis revealed that CNC and PPI interacted mainly through hydrogen bonding. These interactions altered the protein density and cellulose conformation. The radius of gyration (Rg) and root mean square deviation (RMSD) of the protein decreased, indicating enhanced stability, while the dihedral structure of the CNC changed from tg to tg, gt, and gg conformations. These findings suggest that CNC can effectively improve the functional properties of PPI films through hydrogen bonding, offering promising prospects for their application as sustainable food packaging materials.
