Low-Temperature Extrusion Encapsulation of Purpureocillium Lilacinum Spores

Zhongheng Sun developed a starch-based microcapsule delivery system for the biocontrol fungus Purpureocillium lilacinum using food extrusion technology. The dataset includes results on spore release kinetics, particle size changes, and survival after heat treatment, with supporting SEM, XRD, and FT-IR analysis images. The data was uploaded to figshare on May 15, 2026, under a CC-BY-4.0 license.

Use Cases

• Modeling spore release kinetics based on the described sustained-release behavior peaking at 24 hours.
• Analyzing the effect of microencapsulation on spore thermotolerance based on survival data after 60°C heat treatment.
• Studying material properties of starch-based matrices based on XRD and FT-IR data showing gelatinization and V-type crystal formation.
• Evaluating co-encapsulation feasibility based on the inclusion of tomato extract as a flavor and nutritional component.

Strengths

• Includes quantitative data on spore release (~20% to ~80% solubility over 3 days) and particle size reduction (~550 μm to ~35 μm).
• Contains analytical data from multiple techniques (SEM, XRD, FT-IR) supporting the material characterization.
• The dataset is shared under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 2.7 MB size suggests a small dataset, potentially limiting the scope of analysis.
