4. Chemical QualityPlasma chemistry is a complex science involving numerous species in a myriad of chemicalreactions occurring in different time scales [13]. For example, air plasma involves over 75 differentchemical species in almost 500 chemical reactions, making it more complex to understand theirinteraction with food components. However, plasma reactive species are considered to be the majorfactor for all the observed changes in the chemical quality attributes of the treated products, which arediscussed in the following sections. It is worth noting that plasma reactive species are largely dependenton the gas used for plasma generation, making this one of the most critical factors for chemical changes.
