Orange (Citrus sinensis L. Osbeck) plays an important role among Brazilian fruits, with a yearly yield of around 17 million tons in an area of approximately 600,000 ha, representing revenues of U$ 2 billion per year. Brazil exports 30,000 tons of fresh oranges and more than 1 million tons of fresh juice per year, placing the country as the world's leading exporter of orange juice, representing 85% of the global market (Revista Agrobrasil, 2020).Green mould, caused by Penicillium digitatum (Pers.) Sacc, is the major postharvest disease in citrus in all producing countries, and its occurrence depends on climatic conditions and fruit handling, from the orchard to the arrival at the end consumer. The onset of symptoms occurs mainly during storage and transport, reducing both the quality and quantity of marketable fruits (Terao et al., 2017).Currently, the widely used way to control these losses is through the application of fungicides in postharvest treatments, which can leave toxic residues in the fruit (Hjorth et al., 2011). Therefore, the availability of clean technologies and alternatives to the use of fungicides is essential. Among them, bioactive compounds obtained from plants, as well as physical treatments, such as hot water treatment and UV-C radiation, stand out.
