Application of Feruloyl Oligosaccharides in Degradable Chitosan Film

The objective of this research was to investigate the effects of how feruloyl oligosaccharides (FOs) on the physical properties, antioxidant activity, and antimicrobial efficacy of chitosan-based (CS) films. Among the tested formulations, the film containing 10% FOs (CS/FOs-10) demonstrated optimal physical properties, including significant water degradability and excellent extensibility. In vitro antioxidant assays revealed that wheat bran FOs significantly enhanced the overall antioxidant capacity of CS films, with the CS/FOs-15 film achieving an ABTS radical scavenging rate of 96%. Antimicrobial activity tests on both the film-forming solution and film surface indicated that the CS/FOs films exhibited substantial antimicrobial efficacy against Escherichia coli and Staphylococcus aureus compared to the blank control. In practical pork preservation applications, the CS/FOs films effectively inhibited microbial growth, delayed spoilage, and extended shelf life. On the basis of the experimental results and economic considerations, the CS/FOs-10 film demonstrated significant potential for use in meat packaging, providing a scientific foundation for the development of novel, environmentally friendly food packaging materials.
