Abstract
With the development of plasma-activated water (PAW) technology, its applications in the fields of food, agriculture, and biomedicine are becoming increasingly widespread. PAW has sterilization, pesticide residue reduction, anti-cancer, and blood clotting functions. Traditional methods for pesticide degradation include home processing, baking and freeze-drying, and UV treatment; however, they generally suffer from poor degradation efficiency and adverse effects on fruit quality. This study found that PAW treatment is a green and efficient environmental technology with the advantages of simple operation, good treatment effect, and no secondary pollution. This paper investigated the efficiency of PAW on the reduction of two acaricides, namely, bifenazate and spirodiclofen, and the effect of PAW treatment on the quality of Cuimi kumquat. The results showed that after PAW treatment, the residual amounts of bifenazate and spirodiclofen were reduced to a minimum of 1.19 mg·kg−1 and 0.23 mg·kg−1, with a reduction of 74.35% and 59.37% respectively compared to the control. Moreover, PAW treatment did not have any negative effects on the storage quality of Cuimi kumquat.
