Summary: The study examined the microbiological profiles and responses of native microflora of endive to different applications of PFW, finding that multiple applications were more effective than single applications, especially in pre-cleaned endive. The main factors contributing to the antimicrobial efficacy of PFW were high concentrations of nitrite and nitrate, and supporting mechanisms included H2O2 and an acidic pH. These findings provide insights for scaling up successful industrial application of PFW to improve microbiological quality and safety of fresh leafy products.

Summary: This study evaluated the effects of an alginate-based edible coating containing thyme essential oil (AEC-TEO) on the quality and safety of fresh-cut potatoes during a storage period of 16 days at 4 degrees C. The results showed that treatment with AEC-TEO at a 0.05% concentration was the most beneficial for maintaining quality and inhibiting the microorganism growth of fresh-cut potatoes. The reductions in bacterial total counts, total coliform counts, yeast and mold counts, and Lactobacillus counts were 2.41 log cfu/g, 1.37 log cfu/g, 1.21 log cfu/g, and 2 log cfu/g, and Listeria monocytogenes decreased by 3.63 log cfu/g on fresh-cut potatoes after 16 days. Therefore, AEC-TEO effectively improved the quality of fresh-cut potatoes and prolonged their shelf life to a certain extent.

Summary: The study explored the enhanced preservation effect of cactus polysaccharides (CP) combined with ultrasound (US) treatment on fresh-cut potatoes, effectively inhibiting microbial growth and enzymatic browning. The combination treatment had no adverse effects on texture, quality properties, and internal water mobility. In addition, it reduced the activities of polyphenol oxidase and peroxidase, maintained a high level of phenylalanine ammonia lyase activity and total phenol content, and inhibited the peroxidation of membrane lipids. The combination treatment also inhibited the activity of antioxidant enzymes and maintained a high DPPH scavenging ability, while reducing the production of undesirable odors during storage.

Summary: The study demonstrates that atmospheric air plasma bubbles are an effective, energy-efficient, and residue-free alternative for decontamination, with higher plasma discharge frequencies leading to greater reduction in bacterial colony-forming units. Scanning electron microscopy images of treated bacteria show cell damage, while an increase in conductivity and various chemical concentrations in plasma-activated water contribute to the observed antimicrobial effect.

Summary: Postharvest quality deterioration is a major issue in food loss and waste, but the technique of spray-induced gene silencing (SIGS) offers a new solution. By spraying double-stranded RNA (dsRNA) onto the surface of plants, specific genes can be targeted for RNA interference, effectively reducing browning in freshly-cut potatoes. This study highlights the potential application of SIGS in controlling postharvest quality deterioration.

Summary: This study compared the effects of four food additives on fresh-cut potato browning and found that ascorbic acid and L-cysteine treatments reduced browning, while H2S and NO treatments did not. Ascorbic acid inhibited browning by reducing quinones back to phenolic compounds, while L-cysteine mainly decreased PPO and POD activities to inhibit browning.

Summary: In this study, the microbial inactivation efficacy of custom-made FE-DBD plasma at different frequencies on a glass surface was experimentally evaluated. Results showed significant microbial reduction at all frequencies tested. Numerical predictions closely matched experimental data, with a slight difference likely due to complex interactions between plasma species.

Summary: The combination of vacuum packaging and ascorbic acid immersion treatment showed positive effects on the quality of fresh-cut potatoes during storage. It reduced browning, weight loss, and the levels of respiration and ethylene generation, while maintaining firmness. The treatment also suppressed the accumulation of damaging substances, delayed the increase of certain compounds, and preserved the taste and flavor of the potatoes. Moreover, it inhibited the development of rancid off-flavor by suppressing the degradation of fatty acids.

Summary: This study investigated the effect of gap distance between a pin-electrode and water surface on the inactivation efficacy of Escherichia coli (E. coli). The results showed that as the gap distance decreased, the reduction of E. coli increased, and the reactive oxygen species were influenced by the gap distance. Electron spin resonance analysis revealed that the pin-to-water plasma generated hydroxyl radical and singlet oxygen, with superoxide radical serving as a precursor of the hydroxyl radical. Importantly, singlet oxygen (O-1(2)) contributed the most to bacterial inactivation.

Summary: Recycling waste brine from Kimchi production with underwater plasma treatment is an effective method to reduce food-borne pathogens. The use of capillary electrodes supplied by AC bi-polar pulsed power resulted in a linear decrease in microbial population in the waste brine. The quality of salted Kimchi cabbage prepared with plasma-treated waste brine was comparable to newly made brine, indicating the feasibility of reusing waste brine in Kimchi production.

Summary: This study investigated the effect of non-thermal atmospheric plasma (NTAP) treatment on the reduction of residual fludioxonil. Experimental simulation was conducted to simulate the reduction of residual fludioxonil on fruits and vegetables in storage prior to consumption. The results showed that a 10-minute plasma treatment with an O-3 concentration of 11.89 mu L/L achieved a reduction rate of 58.5%. The O-3 concentration was found to be more influential than the treatment time in reducing residual fludioxonil.
