Turkey Berry Nutritional Properties Under Different Drying and Pretreatment Methods

A 2 × 4 factorial design study evaluated the impact of blanching and four drying methods on the nutritional quality of Turkey berry (Solanum torvum). The research assessed moisture, protein, energy, minerals, vitamin C, phenolic content, and antioxidant activity, finding moisture reduced from 81.68% in fresh fruit to 4.19%–8.49% in powders. Authored by Gloria L. Essilfie and shared on figshare in April 2026, the dataset likely contains results from this agricultural processing experiment.

Use Cases

• Compare nutrient retention efficacy based on drying methods (solar, freeze, convection, vacuum) described in the study.
• Analyze the effect of hot-water blanching pretreatment on final moisture content and vitamin C levels.
• Model the relationship between drying method, total phenolic content, and measured antioxidant activity.
• Identify optimal processing combinations for specific nutritional or functional goals in fruit powder production.

Strengths

• Specific quantitative results are provided, such as fresh fruit moisture at 81.68% and dried sample moisture ranging from 4.19% to 8.49%.
• The study design is clearly described as a 2 × 4 factorial evaluating two pretreatments and four drying methods.
• Multiple quality attributes were assessed, including proximate composition, specific minerals (iron, calcium, phosphorus), vitamin C, and antioxidant activity.

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 very small (20.1 KB), indicating limited scope, likely containing summary results rather than raw experimental data.
