The development of plasma technology is associated with the unique features of non-equilibrium low-temperature plasma: high electron energy and high concentration of chemically active excited and charged particles at low gas temperature, which allows to process thermolabile materials and biological objects in gentle conditions when high temperatures are not required. The biological effects of low-temperature plasma exposure are considered. It was established that during plasma treatment, a combined effect on cells and tissues of living systems from UV radiation, ions and chemically active particles occurs. Depending on the plasma type, the significance of each of the listed mechanisms for increasing the effectiveness of plasma treatment may vary. However, all these mechanisms interact with each other and have a synergistic effect. It was shown that the conducted studies confirm the ability of low-temperature plasma to inactivate pathogenic microorganisms upon contact with biological objects and foods. The results of the studies are presented, the purpose of which was to study the effect of plasma treatment on nitrite concentration in the water treated by this method and to assess the possibility of its use as a source of nitrite when curing meat products.
