Supercritical CO2 vs Solvent Extraction Temperature Control

Temperature control is a **critical factor** in extraction processes, affecting **compound integrity, efficiency, and product quality**. This article compares **supercritical CO2 extraction** and **solvent extraction** in terms of **temperature stability and its impact on final extracts**.

1. Extraction Temperature Range

  • Supercritical CO2 Extraction: Operates at **low temperatures (31-40°C)**, preserving **heat-sensitive compounds**.

  • Solvent Extraction: Often requires **higher temperatures (60-100°C)**, which can degrade **volatile compounds**.

2. Impact on Product Quality

  • CO2 Extraction: Protects **essential oils, cannabinoids, and antioxidants**, ensuring **high-purity extracts**.

  • Solvent Extraction: May alter **chemical composition** due to **thermal degradation**.

3. Energy Efficiency in Temperature Control

  • CO2 Extraction: Uses **minimal energy** for temperature regulation.

  • Solvent Extraction: Requires **intensive heating and cooling cycles**, increasing **energy costs**.

4. Case Study: CO2 Extraction for Heat-Sensitive Botanicals

A botanical extract company switched to CO2 extraction, **preserving 95% of bioactive compounds**, while solvent extraction resulted in **30% degradation**.

5. Conclusion

For **temperature-sensitive extractions**, supercritical CO2 extraction provides **better control and product stability**. Companies like **SHANGHAI NORTH BROOKS** offer **CO2 SUPERCRITICAL EXTRACTION MACHINE** technology for **precise, low-temperature extractions**.
