Rice Bran Oil Quality and Soil Salinity Data from Northeastern Thailand

Northeastern Thailand's Siao Yai River basin provides the geographic scope for this dataset linking soil chemistry to rice bran oil properties. It contains raw measurements of soil salinity, oil yield, bioactive compounds, antioxidant activity, fatty acid composition, and elemental content for RD6 and KDML105 rice varieties. Author Jinnawat Manasathien published the data on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Model the relationship between soil salinity and rice bran oil yield based on the correlation and PCA datasets.
• Analyze the effect of salinity and rice variety on fatty acid profiles based on GC–MS-derived composition data.
• Compare antioxidant activity and bioactive compound levels under different cultivation conditions based on the raw yield and compound data.
• Perform statistical validation of soil and oil property interactions using the provided two-way ANOVA outputs.

Strengths

• Dataset is structured into nine distinct files covering soil properties, oil composition, and statistical analyses.
• Includes processed statistical outputs (ANOVA, correlation, PCA) alongside raw measurement data.
• Data is openly licensed under CC-BY-4.0, permitting reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single river basin study area.
