Abstract

For a sustainable future, the search for biodegradable materials to replace conventional petroleum‐based polymers for food packaging has received much attention because of the need to reduce plastic pollution in the environment. Biopolymers are generally biodegradable, renewable, nontoxic, and easily available in nature and can be effective potential alternatives to synthetic plastics. However, the inherent limitations of biopolymers in terms of poor mechanical and barrier properties, as well as inadequate thermal stability, have hindered their widespread adoption in the food packaging industry. With the advent of nanoscience, new avenues for innovation in novel food packaging materials with enhanced functional attributes have been realized. Upon dispersion in a biopolymer matrix, inorganic or organic nanofillers, which possess certain physical and chemical properties at the nanoscale, make these composites useful as packaging materials; tailored mechanical, barrier, thermal, and optical properties have been reported to meet specific requirements for food preservation and packaging. This review discusses the effects of the reinforcement of different types of nanofillers on the mechanical, barrier, antimicrobial and antioxidant properties of biopolymeric matrices used for food packaging applications. The importance of standardized regulations for the safe use of nanomaterials in food packaging has also been discussed in detail.
纳米填料增强生物聚合物复合材料在可持续食品包装中的应用:最新进展
为了可持续发展的未来,寻找可生物降解的材料来取代传统的石油基聚合物用于食品包装,因为需要减少塑料对环境的污染,已经受到了广泛的关注。生物聚合物通常是可生物降解的、可再生的、无毒的、容易在自然界中获得的,是合成塑料的有效的潜在替代品。然而,生物聚合物在机械和屏障性能方面的固有局限性,以及不充分的热稳定性,阻碍了它们在食品包装行业的广泛采用。随着纳米科学的出现,具有增强功能属性的新型食品包装材料的创新途径已经实现。在生物聚合物基质中分散后,具有纳米级物理和化学性质的无机或有机纳米填料使这些复合材料成为有用的包装材料;据报道,定制的机械,屏障,热学和光学性能可满足食品保存和包装的特定要求。本文综述了不同类型纳米填料的增强对食品包装用生物聚合物基质的力学、屏障、抗菌和抗氧化性能的影响。还详细讨论了标准化法规对食品包装中纳米材料安全使用的重要性。
