Low-Temperature CO2 Extraction – Benefits & Applications

Low-temperature CO2 extraction is a highly effective technique for extracting heat-sensitive bioactive compounds, including terpenes, essential oils, cannabinoids, and flavonoids. By maintaining a lower operating temperature (typically 20-50°C), this method preserves fragile compounds, resulting in higher-quality extracts with better potency and flavor.

Using a CO2 SUPERCRITICAL EXTRACTION MACHINE, industries such as pharmaceuticals, cannabis, cosmetics, and nutraceuticals can achieve pure, solvent-free, and thermally stable extracts.

1. What Is Low-Temperature CO2 Extraction?

Low-temperature CO2 extraction is a process that uses subcritical or controlled supercritical CO2 to extract compounds without exposing them to high heat.

  • Preserves Heat-Sensitive Bioactives – Prevents terpene & flavonoid degradation.
  • Enhances Aroma & Flavor – Retains natural essential oils in extracts.
  • Ideal for Delicate Pharmaceuticals & Nutraceuticals – Extracts compounds without chemical modifications.
  • Improves Extraction Efficiency – Higher yields of intact bioactive compounds compared to traditional methods.
