High-Pressure Processing Effects on Lipid Mobilization in Camellia oleifera Seeds

Untargeted UHPLC–Orbitrap metabolomics and targeted GC–MS quantification of 49 free fatty acids reveal how high-pressure processing reshapes early lipid mobilization in Camellia oleifera seeds during a hot–humid postharvest window. The dataset, authored by Jianwen Wu and shared under CC-BY-4.0 on figshare, compares four treatment regimes: untreated baseline, hot–humid holding alone, and holding preceded by HPP at 100 or 500 MPa. Forty-two FFAs were detected with high within-regime reproducibility, showing the 500 MPa regime produced the strongest lipid-mobilization phenotype.

Use Cases

• Compare lipid mobilization responses based on high-pressure processing (HPP) treatment intensity.
• Analyze changes in free fatty acid unsaturation patterns based on the described hot–humid holding conditions.
• Investigate the relationship between untargeted metabolomic divergence and targeted lipid metrics as described in the results.
• Model early seed lipid trajectories before drying based on the defined pressure-primed mobilization window.

Strengths

• Targeted quantification covers 49 specific free fatty acids, with 42 detected.
• Data includes four distinct experimental regimes for comparative analysis.
• Untargeted UHPLC–Orbitrap metabolomics is integrated with targeted GC–MS quantification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (53.7 KB), indicating limited scope.
