Abstract

A novel nanocomposite was developed by integrating zinc oxide nanoparticles (ZnO NPs) into chitosan (CS) matrix and investigated for its impact on the quality and shelf life of refrigerated poultry meat over 11 days. Physicochemical properties including weight, pH, titratable acidity, color, thiobarbituric acid reactive substances assay, microbiological growth studies encompassed total psychotropic and mesophilic aerobic microorganisms, Enterobacteriaceae analyses, and zinc migration levels were conducted to determine the optimal nanocomposite concentration. Results revealed that bio-nanocomposite exhibited superior characteristics compared to chemogenic nanocomposite, chitosan, polyvinyl alcohol, and unwrapped meats. Bio-nanocomposite with reduced unsaturated lipid content extends poultry shelf life to 7 days in packaging, outperforming chemogenic-nanocomposites (5 days) and chitosan (4 days). This study proves that CS/ZnO NP nanocomposite is a promising active packaging material for meat, extending their shelf life without deteriorating its physicochemical characteristics and supporting sustainability, though further research on its toxicological properties is warranted.

壳聚糖/氧化锌氮氧化物生物纳米复合材料在禽肉可持续抗菌食品包装中的创新应用

通过在壳聚糖（CS）基质中添加氧化锌纳米颗粒（ZnO NPs），开发了一种新型纳米复合材料，并研究了它对冷藏禽肉 11 天内的质量和货架期的影响。物理化学特性包括重量、pH 值、可滴定酸度、色度、硫代巴比妥酸活性物质测定、微生物生长研究（包括总精神性和中嗜氧性微生物）、肠杆菌分析和锌迁移水平，以确定最佳纳米复合材料浓度。结果显示，与化学纳米复合材料、壳聚糖、聚乙烯醇和无包装肉类相比，生物纳米复合材料表现出更优越的特性。降低了不饱和脂质含量的生物纳米复合材料将家禽在包装中的保质期延长至 7 天，优于化学纳米复合材料（5 天）和壳聚糖（4 天）。这项研究证明，CS/ZnO NP 纳米复合材料是一种很有前途的肉类活性包装材料，它能延长肉类的货架期，而不会降低其理化特性，并支持可持续发展，不过还需要对其毒理学特性进行进一步研究。

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.
