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

A metabolomics dataset from a 2026 study by Jianwen Wu investigating the effects of high-pressure processing on lipid mobilization in Camellia oleifera seeds during a hot-humid postharvest window. It includes untargeted UHPLC–Orbitrap metabolomics and targeted GC–MS quantification of 49 free fatty acids across four experimental regimes. The data is provided in an XLSX file under a CC-BY-4.0 license.

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

• Includes targeted quantification of 49 free fatty acids, with 42 detected with high within-regime reproducibility.
• Integrates untargeted UHPLC–Orbitrap metabolomics with targeted GC–MS for a multi-faceted analysis.
• Compares four distinct experimental regimes (untreated baseline, hot-humid holding, and two HPP pressures).

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 (37.4 KB), indicating limited scope, likely containing summary or processed results rather than raw instrument data.
