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

A metabolomics dataset from a controlled postharvest experiment on Camellia oleifera seeds, published by Jianwen Wu in 2026. It includes untargeted UHPLC–Orbitrap metabolomics and targeted GC–MS quantification of 49 free fatty acids across four experimental regimes. The data compares untreated seeds with those subjected to hot-humid holding alone and holding preceded by high-pressure processing at 100 or 500 MPa.

Use Cases

• Analyzing pressure-dependent changes in free fatty acid profiles based on targeted GC–MS quantification of 49 FFAs.
• Investigating metabolic divergence from hot-humid holding using untargeted UHPLC–Orbitrap metabolomics data.
• Modeling early seed lipid trajectories before drying based on treatment sequence comparisons.
• Studying membrane-lipid remodeling and oxygenation-associated metabolism in seeds under stress.

Strengths

• Targeted quantification of 49 free fatty acids with 42 detected and high within-regime reproducibility.
• Integrated untargeted metabolomics provides a broader metabolic context for the lipid-focused analysis.
• Data compares four distinct experimental regimes: untreated baseline, hot-humid holding alone, and holding preceded by HPP at 100 or 500 MPa.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The seed-level model requires validation under whole-fruit storage and scale-up conditions, as noted in the description.
