Nonthermal plasma-treated water (PTW) has emerged as a promising area of research, particularly in the food sector, where it shows potential for fresh food sanitation via wash-water processes. When compared to commonly used strong oxidizing sanitizers, only compressed or ambient air and energy are required to generate plasma processed air (PPA), which produces PTW if combined with process or tap water. This excluded hazardous chemical storage and allows dosage and processing on demand.

The publication investigated the decontamination process of porcine umbilical cord tissue using plasma functionalized liquid alone and in combination with ultrasound. The challenge was to achieve lasting and complete decontamination without damaging tissue integrity because viable mesenchymal stem cells were extracted in the following step. The dataset contains numbers of counted colony forming units (CFU) of cultured microorganisms after the different iteration steps of tissue decontamination. Each worksheet summarizes the numbers of one figure.
