Supercritical CO2 vs Steam Distillation Temperature Control

Temperature control is a **critical factor** in extraction processes, influencing **compound integrity, efficiency, and final product quality**. This article compares **supercritical CO2 extraction** and **steam distillation** in terms of **temperature stability and its impact on essential oils and bioactive compounds**.

1. Extraction Temperature Range

• Supercritical CO2 Extraction: Operates at **low temperatures (31-40°C)**, preserving **heat-sensitive compounds**.
• Steam Distillation: Requires **high temperatures (~100°C)**, which can degrade **volatile compounds**.

2. Impact on Product Quality

• CO2 Extraction: Maintains **natural molecular structures**, resulting in **high-purity extracts**.
• Steam Distillation: Heat exposure may lead to **chemical degradation** and **altered aromas**.

3. Energy Efficiency and Sustainability

• CO2 Extraction: Uses **recyclable CO2**, reducing **energy consumption**.
• Steam Distillation: Requires **continuous heating**, leading to **higher energy costs**.

4. Case Study: CO2 Extraction in High-Quality Essential Oils

An essential oil company improved **bioactive retention by 45%** after switching to CO2 extraction.

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**.
