摘要

食品包装已经从过去的笨重和僵硬的形式转变为不同变化的灯光和塑料包装。无论如何变化,包装必须能够保持其原有的功能,即作为食品容器以及保护食品免受外部环境的影响。随着消费者对食物浪费意识的提高,生活水平的提高,提高包装食品保质期的技术发展以及提供食品包装环境指示的方法正在进行中。食品变质有许多不同的指标,但在食品包装中常见的两种气体是氧气和二氧化碳。氧气是食品变质的主要机制,而二氧化碳常用于变气包装。根据文献中不同的概念,也有不同的气体清除和/或传感技术方法。本文将重点介绍纳米材料,即二氧化钛、二氧化硅、沸石和金属有机框架。本综述的结构方式是强调每种材料如何在气体清除和/或指示器应用中使用。本文的最后一部分着重介绍了将纳米材料集成到塑料薄膜中的方法和一些关键问题。

Functions of Nano-Materials in Food Packaging
Food packaging has been changing from bulky and rigid form in the past to different variation of lights and plastic packagings. Regardless of the changes, the packaging must be able to uphold its original function which is to serve as food containment as well as to protect the food from the external environment. Coupled with the increasing consumer’s awareness on food waste, higher standard of living, technological developments are underway to enhance the shelf-life of packed food as well as methods to provide indications of food packaging environment. There are many different indicators for food spoilage, but two commonly found gases in food packaging are oxygen and carbon dioxide. Oxygen is the main mechanism for food spoilage, while carbon dioxide is often used in modified-atmosphere-packaging. There are also different methods of gas scavenging and/or sensing techniques based on different concepts in the literature. In this review, the focus will be on nano-materials, namely titanium dioxide, silica, zeolites and metal organic frameworks. This review is structured in a manner to highlight how each material can be used in both gas scavenging and/or indicators applications. The last part of the review focuses on the approach and some key considerations when integrating nano-materials into the plastic film.
