CO2 Extraction vs Cold Pressing – Which is Better for Essential Oils?

Essential oils are widely used in aromatherapy, cosmetics, and food flavoring. Two popular extraction methods—CO2 extraction and cold pressing—each have advantages and limitations...

1. **Understanding CO2 Extraction**: CO2 extraction utilizes supercritical CO2 to dissolve essential oil compounds, preserving delicate aromas and bioactive compounds while ensuring solvent-free purity...

2. **What is Cold Pressing?**: A mechanical process used primarily for citrus oils, where fruit peels are pressed to release oils. While effective for citrus, cold pressing exposes extracts to oxidation and plant debris contamination...

3. **Key Differences: CO2 vs. Cold Pressing**: CO2 extraction offers higher purity, stronger aroma retention, and better terpene preservation, whereas cold pressing is faster but can degrade delicate compounds...

4. **Industry Applications**: CO2 extraction is preferred for non-citrus essential oils like lavender, peppermint, and cannabis, whereas cold pressing remains suitable for orange, lemon, and lime oils...

5. **Conclusion: Which is Better?**: For high-purity, medicinal-grade essential oils, CO2 extraction is superior. For quick and cost-effective citrus oil production, cold pressing is a viable alternative...
