Abstract
In this study, a novel approach for controlling Citrus sinensis Salustiana green mold disease in oranges was developed using plasma-activated water (PAW) generated by a Surface Dielectric Barrier Discharge (SDBD) system reinforced with H2O2 cold vapor. Penicillium digitatum, the primary cause of orange mold, was the target of the treatment. The efficiency of the setup was investigated in three stages. First, a suspension of P. digitatum spores was directly treated with Ar/H2O2 plasma to estimate the optimal plasma exposure time required for maximum fungal inactivation. Second, the impact of Argon/H2O2 plasma-treated water (PTW), generated from various plasma exposure times, on mold growth on orange peels was examined. For this, orange peels were placed in Ar/H2O2-PTW for different durations, and mold occurrence was monitored. Finally, the effect of PTW, generated from various Ar/H2O2 plasma exposure times, on mold growth on whole oranges was investigated. Oranges were treated with Ar/H2O2-PTW for different durations, and mold occurrence was analyzed. The results demonstrated that a 20-min treatment of oranges with PTW produced from a 420-s Ar/H2O2 plasma exposure time led to complete inactivation of P. digitatum. This study showed that this hybrid scenario can be effectively used for fungal decontamination in the food industry.
期刊介绍:
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
