Abstract
Crown rot is a significant postharvest fungal disease that affects the export of ‘Cavendish’ banana fruit.
It is caused by a complex of phytopathogenic fungi including Colletotrichum musae. The utilization of vapour bioactive compounds with antifungal properties, in particular thymol, is found to be an effective solution for disease control and as an alternative treatment to conventional fungicides.
Zeolitic Imidazolate Framework-8 (ZIF-8) is a highly hydrophobic metal-organic framework (MOF) nanoporous material that can be produced at an industrial scale.
ZIF-8 has been selected as a potential solution for sustained delivery of thymol because the diffusion of volatile organic compounds in ZIF-8 is known to be particularly slow.
This study investigated the impact of thymol vapour released from ZIF-8 on the reduction of internal crown rot in banana fruit packed in corrugated fibreboard carton boxes after 11-d storage at 14°C. Hyperspectral images revealed that thymol released from ZIF-8 resulted in less advanced internal necrosis of crown tissues compared to untreated fruits.
The controlled release allowed the prevention of phytotoxicity in contrast to direct application of thymol in its crystal form.
This study demonstrated the potential utility of thymol released from nanoporous material as a novel strategy for postharvest disease control.
