“…This study adds crucial knowledge to the field of food safety, particularly in using gas plasma technology for toxin degradation. Previous studies have demonstrated the potential of plasma technology in inactivating various pathogens and toxins [ 42 , 43 ]. For example, a review article written by Kutasi et al [ 44 ] highlighted the challenges and approaches towards inactivating aflatoxins using UV radiation and pulsed light treatment, ammoniation, ozonation, and gas plasma.…”

Foodborne diseases can be attributed not only to contamination with bacterial or fungal pathogens but also their associated toxins. Thus, to maintain food safety, innovative decontamination techniques for toxins are required. We previously demonstrated that an atmospheric-pressure dielectric-barrier discharge (APDBD) plasma generated by a roller conveyer plasma device is effective at inactivating bacteria and fungi in foods. Here, we have further examined whether the roller conveyer plasma device can be used to degrade toxins produced by foodborne bacterial pathogens, including aflatoxin, Shiga toxins (Stx1 and Stx2), enterotoxin B and cereulide. Each toxin was spotted onto an aluminum plate, allowed to dry, and then treated with APDBD plasma applied by the roller conveyer plasma device for different time periods. Assessments were conducted using a competitive enzyme-linked immunosorbent assay (ELISA) and liquid chromatography–tandem mass spectrometry (LC-MS/MS). The results demonstrate a significant time-dependent decrease in the levels of these toxins. ELISA showed that aflatoxin B1 concentrations were reduced from 308.6 µg/mL to 74.4 µg/mL within 1 min. For Shiga toxins, Stx1 decreased from 913.8 µg/mL to 65.1 µg/mL, and Stx2 from 2309.0 µg/mL to 187.6 µg/mL within the same time frame (1 min). Enterotoxin B levels dropped from 62.67 µg/mL to 1.74 µg/mL at 15 min, and 1.43 µg/mL at 30 min, but did not display a significant decrease within 5 min. LC-MS/MS analysis verified that cereulide was reduced to below the detection limit following 30 min of APDBD plasma treatment. Taken together, these findings highlight that a range of foodborne toxins can be degraded by a relatively short exposure to plasma generated by an APDBD using a roller conveyer device. This technology offers promising advancements in food safety, providing a novel method to alleviate toxin contamination in the food processing industry.

SummaryMeat is widely regarded as the optimal source of protein for human consumption. However, meat is susceptible to spoilage and microbial contamination throughout processing, transportation and storage stages. Traditional thermal processing techniques are commonly employed in the global meat industry. While these methods ensure microbiological safety, they may also impact the sensory and functional attributes of meat products. To address these limitations, non‐thermal processing technologies are progressively replacing conventional thermal approaches. This review will primarily focus on the potential application of non‐thermal processing technologies as alternatives to traditional methods in meat and meat product processing. Various technologies exhibiting promising performance in this field will be presented. Additionally, the mechanisms, advantages and limitations of these non‐thermal technologies in recent years will be summarised, along with a discussion on the challenges and prospects they present. This study provides an overview of non‐thermal processing technology specifically applied to meat products, emphasising the underlying mechanisms associated with different approaches. By employing diverse technical combinations, it is possible to address existing processing limitations and expand their applicability range. Non‐thermal processing technology demonstrates significant potential for enhancing meat processing practices; however, concerns regarding safety aspects and limited clinical verification about to environmental pollution have impeded its widespread adoption within the food industry.
