High-Quality Pumpkin Seed Oil Production via Supercritical CO2 Technology

1. Advanced Fluid Technology for Botanical Research

Supercritical CO2 (SC-CO2) extraction is the gold standard for researching heat-sensitive lipid compounds. For laboratories focusing on functional oils, the ability to precisely control the fluid state is paramount. This study utilizes pumpkin seed oil—a complex matrix rich in PUFAs (76%+), Tocopherols, and Phylloquinone—to demonstrate the precision and efficiency of our SC-CO2 extraction systems.

2. Technical Specs & Experimental Versatility

Our equipment is designed to handle rigorous orthogonal experimental designs, allowing researchers to isolate variables with high precision.

Precision Pretreatment & Sample Prep

The system supports research into how raw material morphology affects mass transfer:

  • Moisture Sensitivity: Study the impact of water content (optimal <5%) on CO2 penetration.
  • Particle Size Distribution: Fine-tune extraction beds with precision milling (down to 0.5 mm) without risking system clogs or bed compaction.

High-Purity Component Recovery

Unlike Soxhlet extraction, which uses hazardous ethers and high heat, our SC-CO2 systems operate as low-temperature, inert environments. This ensures that the GC-FID analysis of fatty acids reflects the true profile of the biomass, free from thermal degradation or solvent interference.

4. Analytical Performance & Data Reliability

For laboratory users, the equipment’s value is measured by the quality of the extract and the reliability of the data:

  • Yield Efficiency: Achieve an extraction yield of 46% (approaching the theoretical limit of 51.72%).
  • Purity Standards: Extracts meet stringent food-grade and pharmaceutical-grade (GB5009.37-85) standards.
  • Oxidation Stability: Proven protection of unsaturated fatty acids compared to browning-prone Soxhlet methods.

5. Why Equip Your Lab with Our SC-CO2 Systems?

Our supercritical fluid platforms are engineered for researchers who require repeatability and industrial scalability:

  • Modular Design: Easily switch between different biomass types (seeds, leaves, roots).
  • Safety First: Integrated safety valves and high-pressure limiters for lab-safe operation.
  • Data Integration: Compatible with analytical workflows for fatty acid (GC/MS) and physicochemical property testing.
  • From Lab to Pilot: Our parameters provide a direct baseline for scaling up to industrial production.

6. Conclusion: The Ultimate Tool for Lipid Research
