Cold atmospheric pressure plasma is an emerging nonthermal processing technology for the decontamination of foodborne pathogens. This study presents a comparative evaluation of the energy efficiency of the decontamination by three different dielectric barrier discharge (DBD) setups operating in air against Feline calicivirus with a UV‐C lamp. Significant enhancement of the energy efficiency was achieved with a lab‐scale batch reactor prototype, which employed surface DBD, leading to similar energy per unit area requirements as that for UV‐C. A key advantage of plasma over UV‐based disinfection systems is that plasmas are not limited by shadowing effects. Nonetheless, unlike UV‐C, the virucidal efficacy of plasma is significantly reduced for dry samples and remote plasma treatment is only effective against wet samples.

用UV‐C比较评估远程和直接冷空气等离子体的杀病毒效果

大气压冷等离子体是一种新兴的非热加工技术，用于对食源性病原体进行净化。这项研究通过空气中针对猫杯状病毒的三种不同介电势垒放电（DBD）装置，对净化的能效进行了比较评估。使用UV-C灯。实验室规模的间歇式反应器原型采用了表面DBD，实现了能源效率的显着提高，从而导致单位面积的能量需求与UV-C相似。与基于紫外线的消毒系统相比，等离子体的主要优势在于，等离子体不受遮蔽效应的限制。但是，与UV-C不同，血浆对干燥样品的杀病毒功效显着降低，而远程血浆处理仅对湿样品有效。
