Abstract: This study investigated the effects of wheat grass (WG), Aronia melanocarpa extract (AME) and cold plasma (CP) treatments on total phenolic content (TPC), radical scavenging capacity (DPPH) and reducing power (CUPRAC). The findings showed that the AME + CP group had the highest bioactive potential. The TPC value of this group was 64.938 mg GAE/g, which increased by approximately 40% compared to AME without CP treatment. The mixture of WG + AME + CP also showed that CP increased the preservation of phenolic compounds and the extraction efficiency. DPPH activity was determined as 42.626 µmol TE/g in the AME + CP group, and it was observed that CP preserved its radical scavenging capacity. CUPRAC value was 158.422 µmol TE/g, which increased by 5% compared to the group without CP treatment. According to ANOVA analysis, the differences were statistically significant (p < 0.001), and the high effect size (η² > 0.98) supported the strong effect of CP. High Performance Liquid Chromatography (HPLC) analyses showed that chlorogenic acid and cyanidin-3-O-galactoside were more stable with CP. In conclusion, the combination of AME+CP increased bioavailability by reducing oxidative degradation of phenolic compounds, demonstrating the effectiveness of cold plasma technology in improving phenolic stability in functional foods.
