In this study, a novel active film was developed by employing ε-polylysine (ε-PL) as filler in pullulan/curdlan (P/CD) composite (P/CD/ε-PL). The results showed that the structure of P/CD films more uniform and denser compared to pullulan films, due good compatibility intermolecular interaction between them. Among 6:1 improved hydrophobicity, mechanical barrier properties, thermal stability, thereby selecting it for further use. Thereafter, addition ε-PL enhanced structural physicochemical properties prepared P/CD/ε-PL especially P/CD/2.5%ε-PL film. It exhibited ultraviolet (about 80% at 200-400 nm), antibacterial activity (>90% against Staphylococcus aureus Escherichia coli), anti-fog (clearly visible transparent background). Furthermore, exerted its preservation effect on fresh-cut peppers kiwis during storage, delaying softening, consumption soluble solids, deterioration. Therefore, provided promising applications packing Practical Application: Fresh-cut fruits vegetables are prone deteriorate packaging play crucial role retaining their quality. This study conducted prepare blending pullulan, curdlan, explore structural, physicochemical, functional verifying kiwis. Compared polyethylene film, delayed deterioration storage. provides new perspective vegetables.

Pollution caused by nonrenewable plastics has driven the use of natural polymers. Similarly, disposal food waste still harms environment. Considering both aspects, this study aimed to evaluate effect incorporating orange by-product powder (OBP) as a reinforcing material into sodium alginate films with glycerol. Sodium alginate-based were produced using glycerol and various concentrations OBP. The characterized in terms thickness, color, water content, mechanical properties, light transmission, transparency, X-ray diffraction (XRD), Fourier-transform infrared spectrometry (FTIR), contact angle, solubility, swelling, scanning electron microscopy (SEM), thermogravimetric analysis (TGA). addition OBP significantly (
