Residual Solvent Analysis

Residual solvent analysis refers to laboratory testing that detects traces of solvents potentially remaining in cannabis products after extraction or processing. Common solvents tested include butane, propane, hexane, and ethanol—substances used in concentrate production, distillation, or purification workflows. This testing category falls under quality and safety compliance rather than aroma profiling, though solvent residues can affect product flavor and safety profiles. Regulatory frameworks in most legal markets mandate solvent testing to establish that final products meet acceptable thresholds. Results guide processor decisions on extraction methods, post-processing techniques, and product release protocols.

While breeders focus on cannabinoid and terpene genetics, processors working with cultivar-specific material benefit from understanding which plant material characteristics (moisture content, terpene volatility, lipid profiles) may influence solvent retention during downstream processing. This knowledge helps inform breeding priorities for extraction-focused operations.
