In this study, we demonstrate that atmospheric air plasma bubbles are an effective, energy-efficient, residue-free alternative to current decontamination techniques. Five to fifteen minutes of plasma-bubble treatments of inoculated chicken skin led to a significant reduction in colony-forming units (CFUs). We show that the activation efficiency is dependent on the plasma discharge frequency, with a higher one (2,000 Hz) leading to a higher CFU reduction (1.4 log) as compared with a lower (0.3 log) reduction at 1,000 Hz. Scanning electron microscopy pictures of treated bacteria reveal damage to the cells. An evaluation of the physicochemical properties of the generated plasma-activated water revealed an increase in conductivity and in ozone, nitrite, nitrate, hydroxyl, and peroxide concentrations with higher frequencies, all contributing to the observed antimicrobial effect.

使用大气等离子气泡对鸡肉进行微生物净化

在这项研究中，我们证明了大气等离子体气泡是当前去污技术的有效、节能、无残留的替代品。对接种的鸡皮肤进行 5 到 15 分钟的等离子气泡处理后，菌落形成单位 (CFU) 显着减少。我们表明激活效率取决于等离子体放电频率，与 1,000 Hz 时的较低 (0.3 log) 减少相比，较高的放电频率 (2,000 Hz) 导致更高的 CFU 减少 (1.4 log)。处理过的细菌的扫描电子显微镜照片显示细胞受损。对生成的等离子活化水的物理化学性质的评估显示，电导率增加，臭氧、亚硝酸盐、硝酸盐、羟基和过氧化物浓度以更高的频率增加，
