Abstract

The work aims to summarize the application progress and preservation mechanisms of edible composite films loaded with plant essential oil microcapsules and explore their value in the field of food preservation. Starting with edible films, the core components of these composite films were systematically elaborated, including the core materials, wall materials and preparation methods of microcapsules, as well as the preparation methods and preservation applications of the composite films. Furthermore, an in-depth analysis of their preservation mechanisms was provided. The preservation performance of these films benefit from the sustained-release properties of microcapsules, the antibacterial and antioxidant activities of plant essential oils, and the preservation effects of the edible films. The work suggests that future research should focus on strengthening the study of the synergistic effects of these four factors on preservation performance. Potential research directions for edible composite films loaded with plant essential oil microcapsules is outlined, offering theoretical references and practical guidance for the development of high-efficiency preservation materials.
