Stored products may be contaminated by pathogenic fungi such as Fusarium, Aspergillus, Penicillumduring transportation and distribution. Bioactive packaging containing essential oil (EO) nanoemulsion and irradiation treatment can be used to reduce or eliminate pathogen populations while increasing food quality and safety. The possible application of a combined treatment of gamma radiation and biopolymeric diffusion devices encapsulated with plant derived EO emulsions were evaluated against two fungal species Aspergillus nigerand Penicillium chrysogenumon rice grain. The results showed that an enhanced antifungal effect can be achieved by combining a treatment of bioactive films and gamma radiation against A. nigerand P. chrysogenum. The control samples reached up to app. 5-6 log CFU/g during 8 weeks of storage period. The films alone cause app. 1.80-2.80 log CFU/g of reduction depending on mold or polymeric matrices. Gamma radiation alone caused 2-2.40 log CFU/g of fungal reduction, whereas combined treatment caused more than 3-4 log CFU/g of fungal reduction in all cases regardless of polymer matrices and mold species. Thus, combining γ-radiation and EO-loaded bioactive films can offer a better approach in controlling fungal growth in rice during storage.
