Abstract

The food packaging industry generates escalating environmental challenges due to the pervasive use of single-use petroleum-derived plastics, which contribute to climate change, pollution, and microplastic contamination. Polysaccharides have emerged as promising renewable alternatives for food packaging materials. This review critically evaluates recent advances regarding functionalization strategies aimed at improving the mechanical, barrier, and functional properties of polysaccharide-based packaging films. Special attention is paid to chemical modification, blending with bioactive agents, and incorporation of nanomaterials. These strategies significantly enhance the material properties and extend the functionality of polysaccharide-based films, such as antimicrobial, UV-blocking, and pH-indicating capabilities. Life cycle assessment (LCA) and material circularity considerations are provided to compare the environmental sustainability of polysaccharide-based packaging against conventional petroleum-derived plastics, highlighting the environmental trade-offs associated with the adoption of biopolymer-based materials. Additionally, the review critically examines the current limitations and challenges related to scaling up production and achieving cost-effectiveness, thus offering insights into the practical implementation of these materials in the food packaging industry. Finally, key research opportunities are identified, emphasizing the need for further studies to address the challenges of large-scale implementation and cost efficiency in the transition to more sustainable food packaging solutions.

基于多糖的食品包装的进展：功能化策略和可持续性考虑

由于普遍使用一次性石油衍生塑料，食品包装行业产生了不断升级的环境挑战，这有助于气候变化，污染和微塑料污染。多糖已成为有前途的可再生食品包装材料的替代品。这篇综述批判性地评估了最近关于功能化策略的进展，旨在改善多糖基包装薄膜的机械、屏障和功能特性。特别关注的是化学改性，与生物活性剂的混合，以及纳米材料的掺入。这些策略显著提高了材料性能，扩展了多糖基膜的功能，如抗菌、紫外线阻挡和ph指示能力。提供了生命周期评估（LCA）和材料循环考虑，以比较多糖基包装与传统石油衍生塑料的环境可持续性，突出与采用生物聚合物基材料相关的环境权衡。此外，审查严格审查当前的限制和挑战有关扩大生产和实现成本效益，从而提供洞察这些材料在食品包装行业的实际实施。最后，确定了关键的研究机会，强调需要进一步研究，以解决大规模实施和成本效率的挑战，过渡到更可持续的食品包装解决方案。
