CO2 Extraction Pressure and Temperature: Key Factors for High-Purity Extraction

Introduction

CO2 extraction efficiency depends largely on pressure and temperature settings. This article explores how adjusting these factors optimizes the extraction of cannabinoids, essential oils, and pharmaceuticals.

1. The Role of Pressure and Temperature in CO2 Extraction

• Low Pressure (~1,500 psi, 35°C): Best for light terpenes.

• Medium Pressure (~3,000 psi, 45°C): Best for essential oils.

• High Pressure (~5,000 psi, 55°C): Best for cannabinoids and resins.

2. How Different Pressure Ranges Affect Extraction

• Low Pressure: Extracts delicate terpenes.

• Medium Pressure: Extracts essential oils and flavonoids.

• High Pressure: Extracts cannabinoids and resins.

3. Optimizing Temperature for Specific Compounds

• 30-40°C: Best for preserving terpenes.

• 40-50°C: Best for full-spectrum extracts.

• 50-60°C: Best for maximizing cannabinoid yield.
