Special Issue Information

Dear Colleagues,

This Special Issue explores the evolving field of non-thermal processing technologies, highlighting their renewed significance as sustainable solutions for modern food manufacturing. Techniques such as high-pressure processing (HPP), pulsed electric fields (PEF), cold plasma, and ultrasound are gaining significant prominence for their ability to effectively inactivate pathogens and spoilage microorganisms while preserving the food's intrinsic freshness, nutritional value, and sensory characteristics to an exceptional degree. Beyond quality preservation, this Issue will compile cutting-edge research focusing on the profound potential of these technologies to drive sustainability. This includes quantifying reductions in energy and water consumption, as well as, critically, assessing their role in minimizing food waste through shelf-life extension. This direct benefit also connects to packaging optimization, as enhanced product stability can potentially reduce reliance on packaging materials.

We are pleased to invite original research and comprehensive review articles from scholars worldwide. This collection aims to foster a shared vision and collectively advance the global food industry towards a more efficient, sustainable, and environmentally responsible future. We particularly encourage interdisciplinary submissions that bridge fields such as food science, process engineering, and environmental science in order to address complex challenges from multiple perspectives.

The growing demand for alternative meat products is accelerating research into reproductive cell sources for cell-based meat processes, also called cultured meat. Porcine umbilical cord tissue is recognized as an advantageous source of mesenchymal stem cells (MSCs). However, effective decontamination must be achieved without compromising tissue integrity and cell recovery. In this study, we evaluated the decontamination of porcine umbilical cords using plasma-functionalized liquid (PFL) generated by a microwave-driven plasma source. It was applied alone and in combination with ultrasound, with the combined approach demonstrating superior performance. Specifically, the ultrasound–PFL combination treatment reduced the initial microbial load of individual tissue samples, ranging from 4.08 to 7.41 log10 CFU/g, approaching the limit of detection of the applied microbiological assays. Statistical analysis indicated a significant contribution of both PFL and ultrasound to microbial reduction, while mesenchymal stem cell yields (5.4 × 105 cells/g tissue) and cell viability (84%) remained comparable to antibiotic-rinsed controls. Recovered cells retained functional capacity, as demonstrated by successful 3D spheroid formation. These results highlight ultrasound-assisted PFL rinsing as an efficient, long-lasting, and antibiotic-free decontamination strategy without compromising tissue compatibility. This study thereby extends the application of plasma-functionalized liquids and demonstrates the feasibility of sustainable stem cell sourcing. It offers opportunities in cultured meat bioprocessing.
