Supercritical Co2

Supercritical CO₂ is an extraction method rather than a terpene itself, but it is frequently discussed in cannabis genetics and breeding circles because of its role in isolating and studying volatile compounds. In this state, CO₂ behaves as both liquid and gas, making it an efficient solvent for separating cannabinoids and terpenes from plant material while preserving heat-sensitive aromatics. Breeders and researchers use supercritical CO₂ extraction to analyze terpene profiles and cannabinoid ratios in candidate strains, helping inform selective breeding decisions. This technique is often contrasted with solvent-based extraction methods when evaluating how different genetics retain or lose aromatic character during processing.

Breeders employ supercritical CO₂ analysis as a tool for phenotype selection and strain characterization, particularly when evaluating terpene preservation across generations. Understanding extraction profiles helps inform decisions about which parent plants are likely to produce offspring with stable, desirable aromatic and chemical profiles.
