Voc Volatile Organic Compounds

Volatile Organic Compounds (VOCs) represent the broader class of molecules that evaporate readily at room temperature, producing the aromas we associate with cannabis. Terpenes are the primary VOCs in cannabis, but the category also includes other organic compounds like esters, aldehydes, and ketones that contribute to strain-specific scent profiles. Cannabis plants produce VOCs as secondary metabolites, which accumulate in glandular trichomes on flowers and leaves. Understanding VOC composition has become central to cannabis breeding programs seeking to stabilize or enhance particular aroma characteristics. Analytical methods like gas chromatography-mass spectrometry (GC-MS) allow breeders to quantify and compare VOC profiles across cultivars and generations.

Breeders monitor VOC profiles to select for consistent aroma expression and to understand how environmental conditions, curing methods, and genetics interact during cultivation. Knowledge of VOC stability and volatility helps guide decisions about storage, preservation, and breeding lines intended for specific sensory outcomes.
