This study explored the decontamination efficiency of dielectric barrier discharge (DBD) cold plasma using different gases and exposure times at low voltage (20 kV) in chicken breast fillets. Samples were treated by exposure to either oxygen or argon (for 3 and 5 min each), besides the control group, followed by examination for their microbial quality, physicochemical properties, topographical structure, and sensory attributes. Furthermore, the electrical characteristic of the plasma generation system was measured. All plasma-treated samples revealed a significant reduction in bacterial counts, shear force, and pH values, with no significant changes in thiobarbituric acid, total volatile base nitrogen, and cooking loss%. Sensory attributes significantly improved in all plasma-treated samples, except the appearance and color of oxygen-treated samples. This is the first study that demonstrated the impact of DBD plasma on the topographical structure of chicken meat which revealed the greatest destructive effect in muscle fibers and connective tissue in argon-treated samples, with subsequent improving the tenderness versus minimal destructive changes in oxygen-treated samples. Accordingly, DBD plasma treatment, especially with argon gas at 20 kV, for 3 min, is a prospective decontamination method that could be applied safely at poultry processing plants, without any adverse effects on chicken meat quality.

本研究探讨了介质阻挡放电 (DBD) 冷等离子体在低电压 (20 kV) 下使用不同气体和暴露时间对鸡胸肉片的去污效率。除对照组外，样品通过暴露于氧气或氩气（各 3 分钟和 5 分钟）进行处理，然后检查它们的微生物质量、物理化学性质、地形结构和感官属性。此外，测量了等离子体产生系统的电特性。所有经血浆处理的样品均显示细菌计数、剪切力和 pH 值显着降低，而硫代巴比妥酸、总挥发性碱氮和蒸煮损失百分比没有显着变化。所有经血浆处理的样品的感官属性显着改善，除氧处理样品的外观和颜色外。这是第一项证明 DBD 等离子体对鸡肉拓扑结构影响的研究，该研究揭示了氩处理样品中肌肉纤维和结缔组织的最大破坏作用，随后改善了嫩度，而氧气处理的破坏性变化最小样品。因此，DBD 等离子处理，尤其是在 20 kV 的氩气下处理 3 分钟，是一种前瞻性的去污方法，可以安全地应用于家禽加工厂，对鸡肉质量没有任何不利影响。随后改善了氧气处理样品的压痛与最小的破坏性变化。因此，DBD 等离子处理，尤其是在 20 kV 的氩气下处理 3 分钟，是一种前瞻性的去污方法，可以安全地应用于家禽加工厂，对鸡肉质量没有任何不利影响。随后改善了氧气处理样品的压痛与最小的破坏性变化。因此，DBD 等离子处理，尤其是在 20 kV 的氩气下处理 3 分钟，是一种前瞻性的去污方法，可以安全地应用于家禽加工厂，对鸡肉质量没有任何不利影响。
