Supercritical CO2 Extraction vs Traditional Solvent Methods

Choosing between **supercritical CO2 extraction** and **traditional solvent-based extraction** impacts **product purity, efficiency, and sustainability**. This article compares these methods based on **yield, chemical safety, and industrial application**.

1. Purity and Residue-Free Extraction

• Supercritical CO2 Extraction: Produces **solvent-free, high-purity extracts**, ideal for **pharmaceuticals and organic-certified products**.

• Traditional Solvent Methods: Require **solvent removal processes**, with a risk of **chemical residues**.

2. Efficiency and Extraction Yield

• CO2 Extraction: Selectively extracts **targeted bioactives**, reducing **waste and refining steps**.

• Solvent Methods: Often extract **undesirable waxes and lipids**, requiring **additional purification**.

3. Industrial Applications

• CO2 Extraction: Used in **essential oils, pharmaceuticals, cannabis, and high-end botanical extracts**.

• Solvent Methods: Common in **bulk chemical extractions**, but **less efficient for high-quality products**.

4. Case Study: CO2 Extraction in High-Purity Nutraceuticals

A health supplement brand improved **bioactive retention by 45%** after switching to CO2 extraction.

5. Conclusion

For **clean, high-purity extractions**, **supercritical CO2 extraction** is the superior choice. Companies like **SHANGHAI NORTH BROOKS** provide **CO2 SUPERCRITICAL EXTRACTION MACHINE** solutions for **solvent-free, premium-quality processing**.
