САЖЕТАК / ABSTRACT:
Melatonin, a hormone secreted by the pineal gland, is also found in certain seeds, leaves, and fruits, including grapes and wines. It is also produced during vinification through yeast inoculation. Known for its various health benefits, including antioxidant effects and influence on polyphenol biosynthesis in plants, the question arises whether adding melatonin during vinification can enhance wine quality. This study aimed to investigate the impact of melatonin addition on the total phenolic content and antioxidant activity of Moldova red wine. Results indicated an 8% increase in total phenolic content in the treated wine compared to the control. Additionally, the treated wine exhibited higher anti-DPPH radical activity, though no difference was observed in reducing power values between the two wines as measured by the FRAP assay.
