Abstract

Starch-based active packaging has appeared as an emerging strategy, which can effectively replace conventional plastic packaging films. In this study, resveratrol/β-cyclodextrin (RES/β-CD) complex (1 % - 7 % w/w) was incorporated into microcrystalline cellulose/corn starch (MCC/CS) films to improve the functional properties and endow the film with antioxidant and antibacterial activities. The films were evaluated for their microstructure, mechanical, thermal stability, barrier, antibacterial, and antioxidant properties. Result showed that the compatibility between film components was improved by incorporating RES/β-CD complex. XRD results also proved it. ATR-FTIR confirmed the whole hydrogen bond strength of the films was improved. The films with 1 % complex had the highest hydrogen bond strength and excellent film strength. The complex incorporated composite films displayed an upsurge in thermal stability and water vapor barrier property. RES/β-CD complex could improve the antibacterial and antioxidant activity. TOPSIS analysis result showed that MCC/CS-5 % displayed the best comprehensive properties. The results showed that MCC/CS films with RES/β-CD complex could be used as active films for food packaging.

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
