CO2 vs Ethanol Extraction for Food-Grade Products

Introduction

Food-grade extractions require high purity and safety standards. CO2 supercritical extraction and ethanol extraction are widely used, but which is better for food products? Let’s explore their impact on food safety, efficiency, and regulatory compliance.

Extraction Process

CO2 Supercritical Extraction

• Uses non-toxic CO2, leaving no residual solvents.

• Selectively extracts compounds, maintaining food safety regulations.

Ethanol Extraction

• Ethanol is Generally Recognized as Safe (GRAS) but requires post-processing.

• Leaves potential residual solvents, requiring extensive testing.

Regulatory Compliance

• CO2 extraction meets FDA and EU food safety standards with minimal regulatory hurdles.

• Ethanol extraction requires additional purification to comply with food-grade certifications.

Efficiency and Yield

• CO2 supercritical extraction machines extract 90-98% of targeted compounds.

• Ethanol extraction is efficient but less selective, leading to more waste and impurities.

Cost and Sustainability

• CO2 is recyclable, reducing operational costs in the long term.

• Ethanol extraction is energy-intensive, requiring additional solvent recovery processes.

Conclusion

For food-grade extracts, CO2 extraction is the superior choice due to its solvent-free nature, regulatory compliance, and high efficiency.
