“…This might be due to a non-linear inactivation effect of plasma over time (Noriega et al, 2011;. In practice, the both-side treatment for sterilization different food systems is used in electron beam irradiation due to their limited and low penetration power in experimental and industrial processing (Scharf andWieszczycka, 1999 Kim et al, 2010). Our results suggest the better inactivation of S. Typhimurium by both-side APP jet treatment of chicken breast and pork loin.…”

The optimal conditions for applications of an atmospheric pressure plasma (APP) jet for the inactivation of Salmonella Typhimurium in chicken breast and pork loins were investigated. APP jet treatment for 10 min (versus 5 minutes) showed a higher inactivation of S. Typhimurium in an agar plate, with the best effect at a distance of 20 mm. A treatment on both sides (both-side treatment) for 2.5 + 2.5 min showed a greater inhibition on S. Typhimurium growth compared to single-side treatment for 5 min, with reduction levels of 0.66 log CFU/g in chicken breast and 1.33 log CFU/g in pork loin, respectively. However, there was no significant difference between single-side treatment for 10 min and both-side treatment for 5 + 5 min in chicken breasts and pork loin samples. In conclusion, APP jet treatment conditions, including distance, time, and direction, may affect the inactivation efficiency of S. Typhimurium. In this experiment, distance of 20 mm and both-side treatment were the best conditions. Therefore, the optimal APP jet treatment conditions were evaluated to maximize its practical efficiency.

“…E-beam sterilization involves subjecting BC to a beam of high-energy electrons generated by an electron accelerator. 205 This beam penetrates the material, damaging the DNA of microorganisms and rendering them unable to reproduce. 206 One of the significant advantages of e-beam sterilization for BC is its ability to provide rapid and effective sterilization without the need for high temperatures.…”

This review article provides a comprehensive overview of bacterial cellulose (BC), focusing on its physicochemical properties, production methods, purification techniques, and applications. It aims at providing a nuanced understanding of the current state of knowledge in those fields and bridging the gap between academic research and industrial applications. The physicochemical properties of BC, including its chemical structure, morphology, thermal properties, mechanical properties (such as tensile and compression properties), specific surface area, cytotoxicity, and biocompatibility, are discussed. Production methods of BC, including microorganism comparison, culture conditions, and vessel types, are thoroughly explored. Purification methods and sterilization techniques for BC are also addressed. Furthermore, the review highlights industries and applications that have shown interest in BC along with commercially available products, including medical, cosmetic, textile, food ingredients, and scaffolds in cell culture. A conclusion summarizes key findings and potential future directions in BC research and development.

“…However, there was no significant difference between treating a single side for 10 min or both sides for 5 + 5 min. It has previously been noticed, in experiments using electron-beam irradiation, that both sides of a sample need to be treated during sterilization to overcome its low permeability (Scharf et al, 1999;Kang et al, 2012). Zhang et al (1998) showed a double-sided arc plasma.…”

Atmospheric pressure plasma (APP) is an emerging nonthermal microbial inactivation technique. In this study, agar and raw chicken breast were inoculated with Escherichia coli and treated with an APP jet based on cold arc plasma. The aim of this study was to investigate the optimum conditions for the plasma treatment of an APP jet in order to maximize the efficiency of E. coli inactivation. The combination of N2+O2 (10 standard cubic centimeters per minute) and a longer treatment time (10 min) resulted in the highest inactivation of E. coli on agar plates with an optimum treatment distance of 20 mm. The samples in dry and wet conditions showed similar reductions in E. coli count when one side of the samples was treated at a given treatment time. Treating both sides-2.5 min on each side-resulted in a higher growth inhibition of E. coli than treatment of a single side only for 5 min. However, there was no significant difference between one-side treated samples (10 min) and both-sides treated samples (5+5 min). When the concentration of E. coli in the chicken breast sample was 10(4) colony-forming units (CFU)/g, the reduction rate of the E. coli was the highest, followed by 10(5), 10(6), and 10(7) CFU/g; however, no difference was found between 10(3) and 10(4) CFU/g. In conclusion, various treatment conditions may affect the inactivation efficiency of E. coli. In the present study, the optimum condition was determined as the treatment distance of 20 mm and longer treatment time (10 min) with the addition of oxygen to the nitrogen gas flow. Furthermore, the cell concentration of sample was an important parameter for the efficacy of the inactivation process.
