Abstract

In this study, the physicochemical properties of plasma-activated water (PAW) prepared from air,

O_{2} ${{\rm{O}}}_{2}$

Ar $\text{Ar}$

, and

N_{2} ${{\rm{N}}}_{2}$

plasma and the trend of the concentration of reactive oxygen and nitrogen species (RONS) with respect to time were investigated and related to the effect of PAW on navel orange mold. The results showed that

O_{2} ${{\rm{O}}}_{2}$

PAW had a strong lethal effect on navel orange mold and could effectively inhibit the mildewing activity of pathogenic spores. In addition,

O_{2} ${{\rm{O}}}_{2}$

PAW is effective in reducing weight loss and decay of navel oranges during storage. This study suggests the potential application of PAW to prevent fungal infections during storage of agricultural products.

空气、O2、Ar 和 N2 等离子活化水对赣南脐橙霉菌病原体发霉活性的影响

本研究考察了由空气、O2${\rm{O}}}_{2}$、Ar$\text{Ar}$和N2${\rm{N}}}_{2}$等离子体制备的等离子体活化水（PAW）的理化性质以及活性氧和氮物种（RONS）浓度随时间变化的趋势，并将其与等离子体活化水对脐橙霉菌的影响联系起来。结果表明，O2${{\rm{O}}}_{2}$ PAW 对脐橙霉菌有很强的致死作用，能有效抑制病原孢子的霉变活性。此外，O2${{\rm{O}}}_{2}$ PAW 还能有效减少脐橙在贮藏过程中的失重和腐烂。这项研究表明，PAW 有可能被用于预防农产品贮藏过程中的真菌感染。
