Combined effect of antagonistic yeast and modified atmosphere to control Penicillium expansum infection in sweet cherries cv. Ambrunés.
Fruit decay caused by pathogenic moulds is a major concern in the postharvest quality and shelf life of fruit. Blue mould decay is caused by Penicillium expansum (P. expansum) and is one of the most important postharvest diseases in cherries (Prunus avium L.). Synthetic fungicides are the main medium used to control pathogenic moulds. However, alternative approaches are available for developing safer technologies to control postharvest disease. An integrated approach that combines biological control, using antagonistic yeasts and modified atmosphere packaging (MAP) with cold storage is a promising alternative to synthetic fungicide treatment. In this work, two microperforated films (M10 and M50) and two antagonistic yeast strains (Hanseniaspora opuntiae L479 and Metschnikowia pulcherrima L672) were evaluated for their effectiveness to control the development of P. expansum in wounded cherries stored at 1°C. Results showed that the microperforated films had fungistatic effects, particularly M50, due to the level of CO2achieved (mean CO2of 11.2kPa at 35days), and the decrease in disease severity. Antagonistic yeasts, particularly Metschnikowia pulcherrima L672, delayed the development of P. expansum and decreased disease incidence and severity. The combination of MAP and antagonistic yeasts was the most effective approach to control P. expansum, during cold storage.
