Data Sheet 5_High-pressure processing reshapes early lipid mobilization in Camellia oleife

Jianwen Wu's dataset contains metabolomic and lipidomic measurements from Camellia oleifera seeds subjected to different postharvest treatments. The data includes untargeted UHPLC–Orbitrap metabolomics and targeted GC–MS quantification of 49 free fatty acids across four experimental regimes. The dataset was uploaded to figshare on 2026-05-21 and is licensed under CC-BY-4.0.

Use Cases

• Modeling pressure-dependent lipid mobilization based on free fatty acid abundance data.
• Investigating metabolic divergence in seeds based on untargeted metabolomics profiles.
• Analyzing changes in fatty acid unsaturation levels under different postharvest holding conditions.
• Studying the interaction between high-pressure processing and hot-humid intervals on seed lipid trajectories.

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 data for a multi-omics perspective.
• Experimental design isolates seed-level responses across four defined treatment regimes (untreated baseline, hot-humid holding, and two HPP levels).

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 (6.6 KB), indicating a limited scope, likely summary statistics rather than raw instrument data.
