Anthracnose controlled by essential oils: Are nanoemulsion-based films and coatings a viable and efficient technology for tropical fruit preservation?

January 06, 2023 | Foods |

Conducted by Universidade Federal do Rio de Janeiro, Brazil, this study delves into the pressing issue of post-harvest diseases, particularly anthracnose, in the tropical fruit sector. Anthracnose, caused by fungi from the Colletotrichum genus, poses a significant threat to tropical fruits, impacting their appearance and marketability. Conventional antifungals used to combat anthracnose may pose risks to human health and the environment, prompting the investigation of natural alternatives such as essential oils (EOs).

Essential oils have shown promise as biofungicides against anthracnose, but their hydrophobic nature, high volatility, and oxidative instability necessitate stabilization for effective application in food systems. Various delivery systems, including nanotechnology, have been explored to address these limitations and enhance the efficacy of essential oils.

This review provides comprehensive insights into the application of nanotechnology in stabilizing essential oils and highlights its potential to revolutionize anthracnose treatment in tropical fruits. By evaluating current practices involving direct application or incorporation of essential oils into films and coatings, the study offers valuable perspectives for improving disease management and extending the shelf life of tropical fruits, particularly those targeted for export markets.
