| Abstract | Non-thermal atmospheric plasma (NTAP) has been shown to be effective for controlling postharvest fungi in vitro, but little is known about its mode of action, fungal response to NTAP, and the effect of its application on fresh produce. Non-thermal atmospheric plasma was evaluated for its in vitro and in vivo antifungal activity against Alternaria alternata and Botrytis cinerea on paprika. The treatment with NTAP treatment resulted in complete inhibition of mycelial growth of A. alternata, and B. cinerea, particularly at 1000 W for 90 s. The results of in vivo assays demonstrated that NTAP treatment for 90 s inhibited the growth of these fungal pathogens by approximately 55% (A. alternata) and 20% (B. cinerea). The color and hardness of paprika exhibited no significant changes during 7 days of storage after NTAP treatment. The mechanisms by which NTAP treatment decreased fungal growth on paprika were directly associated with the disruption of fungal cell membrane. These findings suggest that the application of NTAP is an effective antifungal treatment approach for preserving paprika. |
