Combination of ionizing radiation and bio-based active packaging for muscle foods: A global systematic review and...

A systematic review and meta-analysis assessed the combined effects of biopolymer-based active packaging and ionizing radiation on muscle foods' quality. Radiation processing of muscle foods reduced the initial counts and growth rates of microbial flora. Irradiation did not affect the initial level of total volatile nitrogen while decreasing its increasing rate during storage. The initial levels and increasing lipid and protein oxidation rates increased after irradiation. Packaging of muscle foods with biopolymer + active compounds before irradiation was the most effective way to decrease microbial flora's initial counts and growth rates. During storage, lower lipid and protein oxidation was found in irradiated muscle foods packed with biopolymer + active compounds. From an industrial standpoint, the packaging of muscle foods with biopolymer + active compounds, particularly plant-based ones, synergistically acts with ionizing radiation to decrease microbial flora counts; therefore, lowering radiation doses can be applied, which minimizes the adverse effects of irradiation on muscle foods.
