Summary: Microcrystalline celluloses were isolated from four agricultural residues and characterized. The obtained microcrystalline celluloses were composited with polylactic acid to form packing films for the preservation of Lanzhou lily. The preservation effect of lily bulbs packaged by the films was significantly improved, and the films prepared from sweet sorghum straw were found to be the most effective.

Summary: A novel composite film for food packaging was prepared using hydroxyethyl cellulose (HEC), carboxymethyl chitosan (CMCS), and zinc oxide nanoparticles by solution casting method. Spectroscopy, crystallography, and morphology observation confirmed the successful incorporation of nanoparticles. The addition of CMCS and ZnO improved the solvent resistance (reduced water solubility by 94.3%) and UV shielding ability (increased UV shielding capacity by 45.73%) of the film, enhancing its potential applications in water-rich foods. The composite film demonstrated efficient inhibition (>99.99% inhibition rate) of pathogenic bacteria Listeria monocytogenes and Pseudomonas aeruginosa, with the synergistic effect of CMCS and ZnO. Furthermore, CMCS and ZnO significantly enhanced the elasticity (494.34% improvement) and maximum load capacity (142.24% improvement) of the composite film.

Summary: Thermoplastic starch was prepared from tapioca starch and thermo-mechanical modified TS using glycerol as a plasticizer and cellulose nanofiber as a reinforcement. The modified starch showed low crystallinity and Vh crystal structure after blending with glycerol. The addition of cellulose nanofiber significantly changed the mechanical properties and increased the glass transition temperature of the modified starch films.

Summary: In this research, pH-sensitive films were prepared using purple-fleshed sweet potato starch and sweet potato peel, and commercial purple sweet potato anthocyanin was incorporated into the films. The addition of anthocyanin resulted in increased thickness, water solubility, and swelling degree, as well as decreased tensile strength and tensile modulus but increased elongation at break of the films. The films showed the fastest color migration in acidic conditions and successfully monitored chicken freshness.

Summary: Active and pH-sensitive films of poly(lactic acid) (PLA)/nanofibrillated cellulose (NFC) were fabricated and tested. The addition of NFC reduced tensile strength but increased flexibility of the films. PLA/EO and PLA/NFC/EO films containing curry exhibited slightly higher strength than thymol formulations. Increasing EO loading improved film flexibility regardless of EO type.

Summary: Biopolymer films, especially starch films, are potential alternatives to non-biodegradable petroleum-based materials due to their cheap cost, abundant availability, and biodegradability. However, the weak mechanical and barrier properties of these films limit their usage. Adding essential oils (EOs) as additives may improve the restricted properties and functionality of the films, but their effects on starch films in food packaging applications are not fully understood. This paper provides an overview of different types of EOs used in solvent casting method-produced starch films, their effects on film properties, and the application of these films in food packaging, particularly for fruits and meats. The films show high potential in extending food shelf life due to the antioxidant and antimicrobial properties of EOs.

Summary: In this study, sugar palm crystalline nanocellulose (SPCNC)-reinforced thermoplastic sugar palm starch (TPS) was blended with poly(lactic acid) (PLA) to balance the individual polymer limitations and prioritize biodegradation feature. The results showed that incorporating SPCNC into TPS led to a significant reduction in water uptake of the blend in all mediums and a slight increase in soil degradation rate. However, PLA40TPS60 and PLA60TPS40 exhibited flammable properties.
