Oxidative Volatilization

Oxidative volatilization describes the chemical process where cannabis plant material undergoes oxidation upon exposure to air, light, or heat, causing volatile compounds to evaporate or transform. This process affects both fresh flower and cured material, altering the terpene profile over time. Common in post-harvest handling, oxidative volatilization can degrade or shift aromas like limonene and myrcene into secondary compounds. Understanding this mechanism is central to preservation strategies in seed storage, flower curing, and breeding selection for stable aroma retention. Breeders often evaluate cultivars for resistance to aroma degradation during typical storage and handling conditions.

Breeders working in aroma stability select for cultivars that retain volatile profiles despite oxidative pressures, particularly important for commercial seed lines and preserved genetics. Cultivars with robust terpene profiles or lower volatilization rates under standard storage are often favored in breeding programs targeting long-term genetic preservation.
