Active packaging (AP) is a new class of innovative food packaging, containing bioactive compounds, is able to maintain the quality of food and extend its shelf life by releasing active agent during storage. The main challenge in designing the AP system is slowing the release rate of active compounds for its prolonged activity. Controlled-release active packaging (CRP) is an innovative technology that provides control in the release of active compounds during storage. Various approaches have been proposed to design CRP. The purpose of this review was to gather and present the strategies utilized for release controlling of active compounds from food AP systems. The chemical modification of polymers, the preparation of multilayer films and the use of cross-linking agents are some methods tried in the last decades. Other approaches use molecular complexes and irradiation treatments. Micro- or nano-encapsulation of active compounds and using nano-structured materials in the AP film matrix are the newest techniques used for the preparation of CRP systems. The action mechanism for each technique was described and an effort was made to highlight representative published papers about each release controlling approach. This review will benefit future prospects of exploring other innovative release controlling methods in food CRP.

主动包装（AP）是一类新型的创新食品包装，包含生物活性化合物，能够通过在储存过程中释放活性剂来维持食品质量并延长其保质期。设计AP系统的主要挑战是减慢活性化合物的释放速度以延长其活性。控释活性包装（CRP）是一项创新技术，可控制储存期间活性化合物的释放。已经提出了各种方法来设计CRP。这篇综述的目的是收集并介绍用于控制食品AP系统中活性化合物释放的策略。聚合物的化学改性，多层膜的制备和交联剂的使用是近几十年来尝试的一些方法。其他方法使用分子复合物和辐射处理。活性化合物的微囊或纳米囊包封以及在AP薄膜基质中使用纳米结构材料是用于制备CRP系统的最新技术。描述了每种技术的作用机理，并努力突出有关每种释放控制方法的代表性发表论文。这项审查将有益于探索食品CRP中其他创新性释放控制方法的未来前景。描述了每种技术的作用机理，并努力突出有关每种释放控制方法的代表性发表论文。这项审查将有益于探索食品CRP中其他创新性释放控制方法的未来前景。描述了每种技术的作用机理，并努力突出有关每种释放控制方法的代表性发表论文。这项审查将有益于探索食品CRP中其他创新性释放控制方法的未来前景。
