Degradation of Zearalenone by Dielectric Barrier Discharge Cold Plasma and Its Effect on Maize Quality

Abstract

In this study, a dielectric barrier discharge (DBD) cold plasma was used to degrade zearalenone, and the degradation efficiency and the quality of maize were evaluated. The results showed that the zearalenone degradation rates increased with the increase in voltage and time. When it was treated at 50 KV for 120 s, the degradation percentage of the zearalenone in maize could reach 56.57%. The kinetics’ analysis showed that the degradation followed a first-order reaction. The crude fiber of the maize reduced after the cold plasma treatment. In addition, cold plasma treatment did not significantly change the crude protein content, but slightly changed the fatty acid and color. The changes in maize quality are generally acceptable. DBD cold plasma may be a promising approach to reducing zearalenone in maize.

Exploring the effects of diluted plasma activated water (PAW) on various sprout crops and its role in autophagy regulation

“…There was a study indicating the potential to enhance crop productivity using the PAW application alone, rather than directly treating plants with plasma [10]. Research has been conducted on the application of PAW in various crops, including pea, rice, and maize [11][12][13]. However, the majority of these studies concentrate on the effects of PAW on crop characteristics such as germination rate and growth.…”
