摘要

本研究研制了一种基于阿魏酸二乙酯(DEF-CDs)的新型碳点,并将其掺杂到聚乙烯醇(PVA)中,制备了一种有效抑制食品光氧化和微生物污染的活性食品包装膜。通过合理的结构设计和前驱体的优化,在聚乙烯醇薄膜中添加0.4% %的deff - cds,可阻挡100% %的紫外光(UV)和99.90% %的高能蓝光(HEBL)。在40天的加速老化试验中,其对UV和HEBL的阻隔能力没有明显下降。此外,DEF-CDs/PVA膜表现出显著的抑菌能力,当DEF-CDs浓度从0 %增加到0.8 %时,对金黄色葡萄球菌的抑菌带直径从8 mm增加到22.8 mm,对大肠杆菌O157:H7的抑菌带直径从8 mm增加到11.8 mm。最后,使用DEF-CDs/PVA薄膜作为活性食品包装,草莓、大枣和牛奶的保质期明显延长。这项工作展示了DEF-CDs作为构建保护性食品包装的多功能纳米增强材料的潜力。

Multifunctional carbon dots with full-band UV-to-HEBL shielding and antibacterial properties in polyvinyl alcohol film for enhancing food preservation
In this study, a new type of carbon dots based on diethyl ferulate (DEF-CDs) was developed, and doped into polyvinyl alcohol (PVA) to prepare an active food packaging film that effectively inhibits photooxidation and microbial contamination of food. Benefit from the rational design of the structure and optimization of the precursor for the DEF-CDs synthesis, 0.4 % of DEF-CDs in PVA film can prevent 100 % ultraviolet light (UV) and 99.90 % high-energy blue light (HEBL). Furthermore, its UV and HEBL blocking capacity shows no significant decline under 40 days of accelerated aging tests. Moreover, the DEF-CDs/PVA film exhibits significant antibacterial capacity, and with the concentration of DEF-CDs increased from 0 % to 0.8 %, the inhibition zone diameters increased from 8 mm to 22.8 mm for Staphylococcus aureus and from 8 mm to 11.8 mm for Escherichia coli O157:H7. Finally, using the DEF-CDs/PVA film as active food packaging, the shelf life of strawberry, jujube and milk was extended significantly. This work exhibits the potential of DEF-CDs as multifunctional nanoreinforcements for constructing protective 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.
