Abstract

A significant surge has occurred in the utilization of the active films sourced from biopolymers, which help to improve the preservation period of foods. In this study, a chitosan-quercetin (Chit-Quer) active packaging film with excellent adhesion, tensile properties, and shape memory was developed, which are conducive to enhancing the sealing and stability of packaging, and are able to adapt to complex shapes and irregular surfaces. The incorporation of quercetin resulted in a rougher and more porous structure of the Chit-Quer composite film with enhanced hydrophilicity and reduced swelling index. The addition of quercetin increased the antimicrobial activity of the composite film to over 90 %. Furthermore, both the oxidized and reduced states of quercetin significantly improved the film’s oxidative resistance. The reduced Chit-Quer film showed the strongest free radical scavenging ability, reaching 80 % within just 5 min, which was a tenfold improvement over the pure chitosan film. In addition, the Chit-Quer film can be completely degraded in about 70 days. Based on the colorimetric alteration of the Chit-Quer film in different pH environments, we further demonstrate that it can be served as an intelligent packaging film for the instant monitoring of crucian carp spoilage. These results indicate that the developed Chit-Quer film is expected to have a substantial impact in the realm of active food packaging, providing more efficient and sustainable protection for food preservation and safety.

基于壳聚糖和槲皮素的多功能绿色食品包装的研制及其对鱼类腐败的可视化监测

来自生物聚合物的活性膜的利用出现了显著的激增，这有助于提高食品的保存期限。本研究研制了一种具有优异附着力、拉伸性能和形状记忆性的壳聚糖-槲皮素活性包装膜，有利于提高包装的密封性和稳定性，能够适应复杂形状和不规则表面。槲皮素的掺入使Chit-Quer复合膜的结构更粗糙，多孔性更强，亲水性增强，膨胀指数降低。槲皮素的加入使复合膜的抗菌活性提高了90%以上 %。槲皮素的氧化态和还原态均显著提高了膜的抗氧化性。还原后的Chit-Quer膜对自由基的清除能力最强，在5 min内达到80% %，比纯壳聚糖膜提高了10倍。此外，Chit-Quer薄膜可在70天左右完全降解。基于Chit-Quer薄膜在不同pH环境下的比色变化，我们进一步证明了它可以作为一种智能包装薄膜，用于实时监测鲫鱼的腐败。这些结果表明，开发的Chit-Quer薄膜有望在活性食品包装领域产生重大影响，为食品保鲜和安全提供更有效和可持续的保护。

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.
