It is known that processing methods ensuring partial or full microbial inactivation are quite limited. Therefore, it is of great interest to develop technique and technologies allowing the effective action on microorganisms without a significant influence on product properties. The use of cold plasma can be one of the promising methods of meat product treatment by cold sterilization. The present work examines a possibility of chilled meat treatment with low-temperature atmospheric-pressure plasma to increase its stability to microbial spoilage and extend shelf life. To obtain low temperature plasma, the equipment developed by the designing department “Plasmamed” was used. Chilled meat was treated with low-temperature atmospheric-pressure argon plasma for 5, 10, 20 and 30 min. Samples were stored at a temperature of 2–4 °C for 10 days. Organoleptic indices, moisture weight fraction, changes in pH and water activity were analyzed before treatment and during storage. Sanitary microbiological analyses were carried out by the following indicators: quantity of mesophilic aerobic and facultative anaerobic microorganisms (QMAFAnM), the presence and quantity of coliforms, Salmonella, Escherichia coli, Listeria monocytogenes, Proteus. It was shown that meat cold treatment with argon plasma inhibited the development of mesophilic microorganisms. The colony forming units detected in the samples after ten days of storage were determined by the duration of exposure to plasma. It was proved that meat treatment for 15 and 30 min had the bactericidal effect and facilitated an improvement in meat color during storage. The organoleptic indices of the samples treated with plasma corresponded to the requirements of standards and approved consumer characteristics.

Surface coating by atmospheric pressure plasma jet (APPJ) polymerization was employed to achieve soil guard protection of textiles. Hexamethyldisiloxane was chosen as a precursor for depositing silicon oxide layers on the fiber surface. Plain-woven polyester and rayon filament fabrics and a geometrically simple poly (ethylene terephthalate) film were used as substrates, which were treated by the APPJ polymerization and by the commonly used two fluorochemical resins for comparison. The samples subjected to the APPJ polymerization showed superior water repellency as compared to the resin-treated samples. Interestingly, the APPJ polymerization provided oleophobicity to diiodomethane and oleophilicity to hexadecane. The deposition of model particulate soils, carbon black and red clay, on the fabrics and the film was evaluated by the surface reflectance method and by microscope image analysis, respectively. It was found that the APPJ polymerization remarkably prevented soil deposition as compared to the treatment with two fluorochemical resins. Contrary to our expectations, the APPJ polymerization did not significantly affect the removal of the particulate soils from the substrates by aqueous cleaning.
