Camellia Oleifera Seed Lipid Metabolomics Under High-Pressure and Hot-Humid Conditions

Jianwen Wu's dataset contains metabolomic profiles of Camellia oleifera seeds under postharvest stress. It integrates untargeted UHPLC–Orbitrap metabolomics with targeted GC–MS quantification of 49 free fatty acids across four experimental regimes. The data was last updated on 2026-05-21.

Use Cases

• Analyzing pressure-dependent lipid mobilization responses based on targeted free fatty acid quantification.
• Comparing metabolic divergence between treatment regimes based on untargeted metabolomics data.
• Investigating membrane-lipid remodeling and oxygenation-associated metabolism in seeds under stress.
• Modeling early seed lipid trajectories before drying based on treatment sequence.

Strengths

• Targeted quantification of 49 free fatty acids, with 42 detected with high within-regime reproducibility.
• Integrated untargeted metabolomics provides a broader view of metabolic changes.
• Data compares four distinct experimental regimes: untreated baseline, hot-humid holding alone, and two HPP pre-treatments.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (184.6 KB), indicating limited scope.
