Background

The ever-growing world population results in the ineluctable increase of food demand which translates in the augment of the global market of packaging materials. Hence, the concept of active packaging materializes as a technology to enhance the safety, quality and shelf-life of the packaged foods. Active packaging systems can contribute to the reduction of food waste by providing, apart from an inert barrier to external conditions, several functions associated with food preservation, namely absorbing/scavenging, releasing/emitting and removing properties, temperature, microbial and quality control.

Scope and approach

The purpose of this review is to present a concise (but wide-ranging) appraisal on the latest advances in active agents for active food packaging. Emphasis is placed on active functions such as antimicrobial and antioxidant activity, oxygen and ethylene scavenging, and carbon dioxide emitting. An effort was made to highlight representative articles that prompted research on active agents towards viable market solutions.

Key findings and conclusions

Active packaging is a thriving field given its duality as barrier to external detrimental factors and active role in food preservation and quality. The use of natural active agents is a flourishing field due to the general concern towards natural-based additives. Nevertheless, research is still in its early stages with a long way to go in the design of innovative and economical active packaging materials containing appropriate active agents. The interaction between packaging, environment and food is the key challenge for achieving commercial translation.

活性食品包装用活性剂简明指南

背景

世界人口的不断增长导致粮食需求的不可避免的增长，这转化为包装材料全球市场的扩大。因此，主动包装的概念成为一种提高包装食品安全性，质量和保质期的技术。主动包装系统可通过提供除对外部条件的惰性屏障外，还具有与食品保存相关的多种功能，即吸收/清除，释放/释放和去除特性，温度，微生物和质量控制，从而有助于减少食品浪费。

范围和方法

此次审查的目的是对活性食品包装用活性剂的最新进展进行简要（但范围广泛）评估。重点放在诸如抗菌和抗氧化活性，清除氧气和乙烯以及排放二氧化碳等活性功能上。努力突出具有代表性的文章，这些文章促使人们对活跃代理商进行研究，以寻求可行的市场解决方案。

主要发现和结论

主动包装是一个蓬勃发展的领域，因为它具有双重性，既可以阻止外部有害因素，又可以在食品保鲜和质量方面发挥积极作用。由于对天然基添加剂的普遍关注，天然活性剂的使用是一个蓬勃发展的领域。然而，在设计包含适当活性剂的创新且经济的活性包装材料方面，研究仍处于早期阶段，还有很长的路要走。包装，环境和食品之间的相互作用是实现商业翻译的主要挑战。
