“…Authors related the antifungal activity with the presence of chlorogenic and hydroxybenzoic acids and gallocatechin in the aqueous extracts. Furthermore, in another study, coconut mesocarp extracts were incorporated as an additive into a chitosan matrix, and the results showed good biocompatibility of the extracts with the polymeric matrix by enhancing the physicochemical and antifungal properties of films and coatings, protecting tomato fruits against Geotrichum candidum establishment [11]. This study determined the antifungal capacity of coconut mesocarp extracts against Fusarium musae and their impact on fungal control in bananas.…”

Crown rot, caused by Fusarium species, is the most devastating postharvest disease in bananas. Fungicides are traditionally applied as a postharvest treatment to control crown rot in bananas. However, there is a need to research environmentally friendly compounds as postharvest treatments instead of chemical fungicides. The phenolic compounds gallic acid, protocatechuic acid, and chlorogenic acid were identified in coconut mesocarp extract. Overall, the treatments were more efficient in crown-based than fruit-based culture mediums. The mycelial development was inhibited in a range from 20 to 26% (applying coconut mesocarp extract at 5%) compared to the control. Sporulation and spore germination were significantly inhibited, with a reduction of 88% in spore production and 91% in spore germination inhibition compared to the control. In in vivo tests, the aqueous extracts were effective by limiting the percentage of infected fruit, crown rot, and fruit severity. The use of coconut mesocarp extracts can be an effective and environmentally friendly alternative to the use of fungicides for controlling Fusarium musae on bananas.

“…Considering that the polymeric matrix may serve as a carrier for a wide range of additives, the use of edible coatings for disease management has grown in favor in recent years, and the application of combined treatments has significantly reduced the presence of phytopathogenic microorganisms in many studies [55,[101][102][103]. These activities are integral to fruit quality deterioration during the post-harvest stage, involving elevated ethylene levels.…”

The effects of phytopathogenic fungi on fruits and vegetables are a significant global concern, impacting various sectors including social, economic, environmental, and consumer health. This issue results in diminished product quality, affecting a high percentage of globally important fruits. Over the last 20 years, the use of chemical products in the agri-food sector has increased by 30%, leading to environmental problems such as harm to main pollinators, high levels of chemical residue levels, development of resistance in various phytopathogens, and health issues. As a response, various organizations worldwide have proposed programs aimed at reducing the concentration of active compounds in these products. Priority is given to alternative treatments that can mitigate environmental impact, control phytopathogens, and ensure low residuality and toxicity in fruits and vegetables. This review article presents the mechanisms of action of three alternative treatments: chitosan, citral, and hexanal. These treatments have the potential to affect the development of various pathogenic fungi found in tropical and subtropical fruits. It is important to note that further studies to verify the effects of these treatments, particularly when used in combination, are needed. Integrating the mechanisms of action of each treatment and exploring the possibility of generating a broad-spectrum effect on the development of pathogenic microorganisms in fruits is essential for a comprehensive understanding and effective management.
