Sweet Sorghum Seed Hygroscopicity Data at Varied Temperatures and Moisture Levels

Experimental data on the hygroscopic properties of sweet sorghum seeds. The dataset includes sorption isotherms measured at temperatures of 10, 20, 30, and 40 °C and moisture levels from 8% to 24% (dry basis). It was created by Renan Ullmann and models the relationship between water activity and moisture content, with isosteric heat of sorption values ranging from 2493.33 to 3136.54 kJ.kg⁻¹.

Use Cases

• Modeling seed drying and storage conditions based on temperature and water activity data.
• Fitting and comparing sorption isotherm models based on experimental moisture content data.
• Estimating energy requirements for desorption processes based on isosteric heat values.

Strengths

• Experimental data covers four specific temperature points (10, 20, 30, 40 °C).
• Includes measurements across five distinct moisture content levels (8%, 12%, 15%, 19%, 24% dry basis).
• Provides a specific range for isosteric heat of sorption (2493.33 to 3136.54 kJ.kg⁻¹).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
