Yield and Viscosity of Neem and Castor Oils from Paraíba, Brazil

Juarez Benigno Paes authored a study evaluating the oil yield, moisture content, density, and viscosity of neem (Azadirachta indica) and castor (Ricinus communis) plants. The work involved collecting fruits from specific locations in Paraíba state, Brazil, and extracting oils with absolute ethyl alcohol. Castor oil presented lower moisture content and yield but higher density and viscosity compared to neem oil.

Use Cases

• Compare oil yield and moisture content between neem and castor species based on the described experimental results.
• Model the relationship between oil concentration and solution viscosity based on the described density and viscosity measurements.
• Assess the suitability of neem and castor oils for bio-lubricant or fuel applications based on their physical characteristics.

Strengths

• Study provides specific comparisons between two plant oil species, noting castor oil had lower moisture content and yield but higher density and viscosity.
• Data collection is described with specific geographic origins in Paraíba state, Brazil.

Limitations

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