中文摘要:

      传统的塑料食品包装材料大多来自于不可再生的石化资源, 难以降解, 不仅造成白色污染, 且包装中的某些成分迁移至食品中也给食品安全带来负面影响。随着对“双碳目标”的认知和食品安全关注度的提升, 绿色、安全、可降解同时可延长食品的保质期的生物基活性包装材料成为研究热点。本文从活性剂的类型和活性包装的功能角度介绍了生物基活性基材的类型和特点, 综述了基于淀粉、纤维素、壳聚糖、蛋白质、聚乳酸等生物基材的活性食品包装材料的研究现状, 对比分析不同类型生物基活性包装的优势和弊端, 探讨各生物基食品活性包装材料存在的问题及解决的对策, 最后对未来生物基活性包装的应用和研究趋势进行展望, 以期为开发和选用绿色环保、性能优良、使用安全的生物基活性食品包装提供参考。

英文摘要:

      Most of traditional plastic food packaging materials come from non-renewable petrochemical resources and are difficult to be degraded, which not only cause white pollution, but also bring negative impacts on food safety when some components in the packaging migrate into the food. With the increasing awareness of the “double carbon target” and attention on food safety, green, safe, degradable, and biobased active packaging materials have become a hot research topic, which can extend the shelf life of food. This paper introduced the types and characteristics of bio-based active substrates from the perspective of the types of active agents and the function of active packaging, reviewed the research status of active food packaging materials based on starch, cellulose, chitosan, protein, polylactic acid, etc., compared and analyzed the advantages and disadvantages of different types of active food packaging, and discussed the existing problems and solutions of bio-based food active packaging materials. Finally, this paper prospected the future application and research trend of bio-based active packaging, in order to provide references for the development and adoption of green, environmental-friendly, excellent performance, and safe use of bio-based active food packaging.
