Nonthermal plasma
A nonthermal plasma is in general any plasma which is not in thermodynamic equilibrium, either because the ion temperature is different from the electron temperature, or because the velocity distribution of one of the species does not follow a Maxwell–Boltzmann distribution.
== Applications ==
In the context of food processing, a nonthermal plasma (NTP) is specifically an antimicrobial treatment being investigated for application to fruits, vegetables and other foods with fragile surfaces.〔(【引用サイトリンク】title=Decontamination of Fresh Production with Cold Plasma )〕
These foods are either not adequately sanitized or are otherwise unsuitable for treatment with chemicals, heat or other conventional food processing tools. The term ''cold plasma'' has been recently used as a convenient descriptor to distinguish the one-atmosphere, near room temperature plasma discharges from other plasmas, operating at hundreds or thousands of degrees above ambient (see here for more on plasma temperatures). Within the context of food processing the term "cold" can potentially engender misleading images of refrigeration requirements as a part of the plasma treatment. However, in practice this confusion has not been an issue.
Nonthermal plasma also sees increasing use in the sterilization of teeth〔(【引用サイトリンク】title=Plasma rips away tenacious tooth bacteria )〕 and hands, in hand dryers as well as in self-decontaminating filters.
