Volatility And Oxidation

Volatility and oxidation describe how cannabis terpene profiles change over time through exposure to air, light, and temperature. Terpenes are organic compounds with varying vapor pressures—some evaporate readily (high volatility), while others persist longer in stored material. Oxidation occurs when terpenes react with oxygen, degrading their molecular structure and altering aroma character. Breeders and cultivators track these processes because they affect the stability of a strain's sensory profile from harvest through storage. Understanding volatility is particularly relevant for preservation protocols, as certain genetic lines produce terpene combinations that shift more noticeably than others under standard conditions.

Breeders working with volatile terpene lineages—such as those emphasizing limonene or pinene-dominant profiles—often cross for genetic stability or pair with more oxidation-resistant chemotypes. Seed companies document how parent lines' terpene retention affects F1 and F2 stability, informing selection decisions for consistent commercial phenotypes.
