活性包装释放控制的研究进展

Progress in controlled release for active packaging

活性包装是以包装材料为传送载体,释放抗菌剂、抗氧化剂等保鲜剂以达到维持或改善食品品质,延长食品的货架期的包装技术。本文从释放动力学过程展开探讨,分类介绍了释放控制的四种方式:树脂基体组成、多层复合、纳米材料复合及微囊化,最后从活性包装保鲜效果评价进行释放与保鲜的关联,并提出了展望。

Active packaging is a new package technology which uses packaging material as the carrier and releases the preservatives such as antibacterial agents and antioxidant agents to preserve the food quality and extend the shelf life. In this study, the progress of the research on the release-active packaging with the antibacterial and antioxidant properties was reviewed.Firstly a general introduction was given to kinetics of release. Then the four ways of releasing control including resin composition, multilayer composition, nano material composition, and encapsulation were introduced in detail. Finally, the future trends and prospects in the development of active packaging were highlighted.
