Recent advances and trends in the use of these alternative postharvest treatments on anthracnose decay in avocados, mangoes, and papayas

Subtropical fruit such as avocados (Persea americana), mangoes (Mangifera indica L.), and papayas (Carica papaya L.) are economically important in international trade and predominantly exported to European destinations. These fruits are highly consumed due to their health benefits. However, due to long-distance shipping and the time required to reach the retail department stores, postharvest losses, due to postharvest decay occurring during the supply chain, affect the fruit quality on arrival at the long-distance distribution points. Currently, the use of synthetic fungicide, Prochloraz?, is used at the packing line to reduce postharvest decay and retain the overall quality of mangoes and avocados. Due to the ban imposed on the use of synthetic fungicides on fresh fruit, several studies have focused on the development of alternative technologies to retain the overall quality during marketing. Among the developed alternative technologies for commercial adoption is the use of edible coatings, such as chitosan biocontrol agents and essential oil vapors. The objective of this review is to summarize and analyze the recent advances and trends in the use of these alternative postharvest treatments on anthracnose decay in avocados, mangoes, and papayas. Contents Introduction Edible Coatings and Additives Nanomaterial Antifungal Properties Nanomaterials and Nano-Chitosan Coating Essential Oils Biocontrol Concluding Remarks Alternative treatments, edible coatings, films and additives, nanomaterials, essential oils, and biocontrol agents could be more effective during integrated combination via a ?hurdle concept? due to their different mechanisms. The alternative products replacing the commercial synthetic fungicides should not affect the fruit quality or sensory properties of the fruit. In addition, during the application, the product should not affect the environment and other organisms that are agriculturally friendly. Furthermore, the practical application, reliability of the product, commercialization, registration, and cost-effectiveness of the treatments are important before recommending the treatments to the avocado, mango, and papaya industries.
