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.

白藜芦醇/β-环糊精配合物增强微晶纤维素/玉米淀粉活性包装的制备与表征

淀粉基活性包装作为一种新兴的包装策略而出现，它可以有效地取代传统的塑料包装薄膜。本研究将白藜芦醇/β-环糊精（RES/β-CD）配合物（1 % ~ 7 % w/w）掺入微晶纤维素/玉米淀粉（MCC/CS）膜中，以改善膜的功能特性，并赋予膜抗氧化和抗菌活性。对膜的微观结构、机械性能、热稳定性、阻隔性、抗菌性和抗氧化性进行了评价。结果表明，RES/β-CD配合物的掺入改善了膜组分间的相容性。XRD结果也证明了这一点。ATR-FTIR证实膜的整体氢键强度得到了提高。配合物含量为1 %的膜具有最高的氢键强度和优异的膜强度。复合膜的热稳定性和水蒸气阻隔性能均有显著提高。RES/β-CD配合物可以提高其抗菌和抗氧化活性。TOPSIS分析结果表明，MCC/CS-5 %具有最佳的综合性能。结果表明，具有RES/β-CD配合物的MCC/CS薄膜可作为食品包装的活性膜。

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.
