Abstract
This research investigates the chemical composition of Philippine duhat (Syzygium cumini l.) across different maturation stages: one-day, three-day, five-day, and seven-day-old samples. The study aimed to analyze the variations in titratable acidity, volatile compounds and the concentrations of essential and trace elements, including zinc, iron, lead, copper, chromium, and potassium. Advanced techniques such as Atomic Absorption Spectroscopy (AAS) and Gas Chromatography-Mass Spectrometry (GC-MS) were employed for a comprehensive analysis. Significant changes were observed in titratable acidity, indicating a maturation-dependent alteration in the taste profile and sugar content. The AAS results revealed stable concentrations of the analyzed metals, suggesting consistent metal profiles during the fruit's maturation. GC-MS metabolomic profiling uncovered an interesting phytochemical evolution. Early stages were marked by the presence of putatively identified Alpha-bergamotene, evolving to a more complex array of putatively identified sesquiterpenes such as Caryophyllene, Humulene, and β-curcumene in the later stages. The results indicate no significant variations in trace metal concentrations, while substantial changes in titratable acidity and soluble solids were observed, reflecting the dynamic nature of the biochemical processes during the maturation of duhat. These findings provide valuable insights into agricultural practices, food industry applications, and consumer awareness, emphasizing the potential of duhat in various domains.
