Solvent Based Processing

Solvent-based processing refers to extraction methods that use chemical solvents—such as butane, propane, ethanol, or hexane—to separate cannabinoids and terpenes from plant material. These techniques are distinct from solventless methods (rosin, dry-sift) and produce concentrates ranging from shatter to budder depending on post-processing agitation and temperature. Solvent choice, residual solvent levels, and purging protocols significantly impact final terpene retention and product safety. Understanding solvent polarity and volatility helps explain why different solvents extract different terpene profiles and cannabinoid ratios. Breeders and processors track terpene behavior under specific solvent systems to optimize extraction efficiency and preserve aromatic compounds.

Breeders working with cultivars destined for solvent extraction often prioritize terpene stability and yield. Strains with robust terpene profiles—particularly those with heat-stable monoterpenes and sesquiterpenes—are valued in commercial extraction programs, as solvent processing can strip volatile compounds during evaporation and purging.
