Abstract :The edible portion of Brussels sprouts, their sprouts, is recognized for its high nutritional value. These sprouts are rich in glucosinolate compounds, which play a crucial role in enzyme regulation, DNA protection against degradation, and cancer prevention. However, the storage life of Brussels sprouts is relatively short. Thus, this study targeted to investigate the impacts of different melatonin concentrations (50 µM, 100 µM, and 150 µM) on the postharvest quality of Brussels sprouts. Brussels sprouts were immersed in melatonin solutions at concentrations of 50 µM, 100 µM, and 150 µM for 5 minutes, with pure water serving as the control. Following immersion, the sprouts were stored at 1 ± 0.5 °C and 90 ± 5% relative humidity (RH) for 28 days. Key quality criteria, including weight loss, titratable acidity, soluble solids content, vitamin C, chlorophyll, total phenolic content, and total antioxidant capacity, were analyzed at every seven days (on days 7, 14, 21, and 28). Melatonin treatments significantly influenced the postharvest quality of Brussels sprouts. The highest chlorophyll content was noted in the 50 µM melatonin treatment, whereas the maximum vitamin C levels were recorded in both the control and 50 µM melatonin applications. The greatest total antioxidant capacity was achieved with the 100 µM melatonin treatment. Conversely, weight loss and total phenolic content were not significantly affected by melatonin applications. In conclusion, the application of 50 µM melatonin was found to effectively preserve the quality of Brussels sprouts, allowing for commercial storage of up to 28 days.
