Abstract
Non-thermal plasma (NTP) presents a promising technique for surface disinfection and microbial decontamination. This study explores NTP's effectiveness on three surface materials—aluminum, glass, and acrylic—by comparing disinfection performance under identical treatment conditions. This investigation introduces the first-ever regrowth potential assessment, evaluating the regrowth of microbes post-NTP treatment. The research examines in depth mechanisms of regrowth and the factors influencing it, utilizing characterization techniques such as Fourier transform infrared spectroscopy (FTIR)-attenuated total reflectance (ATR), scanning electron microscopy (SEM), X-Ray photoelectron microscopy (XPS), and contact angle measurements. The results contribute to the assessment of microbial regrowth potential, providing an informative reference for evaluating the duration of NTP disinfection and helping to improve its practical application.
期刊介绍：
The journal publishes original research and review papers on any subject at the interface between food and engineering, particularly those of relevance to industry, including:
Engineering properties of foods, food physics and physical chemistry; processing, measurement, control, packaging, storage and distribution; engineering aspects of the design and production of novel foods and of food service and catering; design and operation of food processes, plant and equipment; economics of food engineering, including the economics of alternative processes.
Accounts of food engineering achievements are of particular value.
