Volatile Organic Compound Profiling

Volatile Organic Compound (VOC) profiling is the systematic analysis and categorization of aromatic molecules released from cannabis plant material. These compounds—including terpenes, esters, and other volatile secondary metabolites—form the chemical basis for strain-specific aroma signatures. VOC profiling relies on techniques such as gas chromatography and mass spectrometry to map the complete aromatic profile of a cultivar. Understanding VOC composition has become central to modern cannabis breeding, as breeders select for specific terpene combinations to establish consistent sensory and chemical traits across generations. VOC profiles serve as objective markers for strain differentiation and lineage verification in formal breeding programs.

Breeders use VOC profiling data to identify parent plants with complementary aromatic profiles, predict offspring terpene outcomes, and stabilize desirable scent characteristics in new cultivars. Detailed VOC analysis helps document genetic lines and supports selective breeding for specific compound ratios that define family characteristics.
