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.

Melatonin Uygulamalarının Depolama Süresince Brüksel Lahanalarının Kalite Özellikleri Üzerindeki Etkisi

Öz

Brüksel lahanasının yenilebilir kısmı olan filizleri, yüksek besin değeriyle tanınır. Bu filizler, enzim düzenlenmesinde, DNA'nın bozulmaya karşı korunmasında ve kanser önlenmesinde önemli rol oynayan glukozinolat bileşikleri açısından zengindir. Ancak, Brüksel lahanasının depolama ömrü nispeten kısadır. Bu nedenle, bu çalışma farklı melatonin konsantrasyonlarının (50 µM, 100 µM ve 150 µM) Brüksel lahanasının hasat sonrası kalitesi üzerindeki etkilerini araştırmayı hedeflemiştir. Brüksel lahanaları, kontrol olarak saf su kullanılarak 50 µM, 100 µM ve 150 µM konsantrasyonlarındaki melatonin solüsyonlarına 5 dakika daldırıldı. Daldırmanın ardından filizler 1 ± 0,5 °C ve %90 ± 5 bağıl nemde (RH) 28 gün boyunca saklandı. Ağırlık kaybı, titre edilebilir asitlik, çözünür katı madde içeriği, C vitamini, klorofil, toplam fenolik içerik ve toplam antioksidan kapasitesi dahil olmak üzere temel kalite kriterleri her yedi günde bir (7., 14., 21. ve 28. günlerde) analiz edildi. Melatonin uygulamaları Brüksel lahanalarının hasat sonrası kalitesini önemli ölçüde etkiledi. En yüksek klorofil içeriği 50 µM melatonin uygulamasında kaydedildi, maksimum C vitamini seviyeleri ise hem kontrol hem de 50 µM melatonin uygulamalarında kaydedildi. En büyük toplam antioksidan kapasiteye 100 µM melatonin uygulamasıyla ulaşıldı. Öte yandan, ağırlık kaybı ve toplam fenolik içerik melatonin uygulamalarından önemli ölçüde etkilenmedi. Sonuç olarak, 50 µM melatonin uygulamasının Brüksel lahanalarının kalitesini etkili bir şekilde koruduğu ve 28 güne kadar ticari depolamaya olanak sağladığı bulundu.
