To elucidate the effects of plasma-synthesized N₂O₅ gas on the secondary metabolism of strawberries, N₂O₅ gas was sprayed onto strawberry seedlings using an atmospheric-pressure air plasma device. Absorbance measurements of fruit extracts were conducted, and comparison with an untreated control group suggested that N₂O₅ treatment may affect anthocyanin content. In this presentation, we report the effects of treatment conditions, including the spraying method and exposure time of N₂O₅ gas, on anthocyanin content and discuss the underlying mechanisms of its action.
