Plasma‐electrified postharvest preservation of Citrus sinensis: Process technology and freshness‐keeping and anticorrosion effects

Abstract Nitrogen oxide‐generating dielectric barrier discharge plasma is shown to effectively inhibit microorganisms and maintain fruit freshness. Physical and biological mechanisms of the plasma‐electrified fungicidal effects suggest that plasma‐generated NO and ONOO − species and other factors are crucial to regulating physiological senescence in citrus fruit while controlling pathogens on their surface. The revealed Physico‐chemical effects explain the observed phenotypic changes and the suppression of surface pathogens, thus providing mechanistic insights into postharvest fruit processing with plasmas.
