Oxidative Degradation

Oxidative degradation refers to the chemical breakdown of terpenes and cannabinoids when cannabis material is exposed to oxygen, light, and heat over time. This process occurs naturally during storage, drying, and curing, and can significantly alter the volatile compound profile of dried flower or concentrate. Breeders and cultivators track oxidative stability as a preservation concern, since more stable chemotypes maintain their original terpene profiles longer. Understanding oxidative degradation is essential for seed preservation, storage protocol development, and predicting how a strain's aroma and chemical composition will evolve post-harvest. Different terpene families show varying resistance to oxidation—for example, some monoterpenes degrade faster than sesquiterpenes under identical conditions.

Breeders working with heirloom or heritage genetics prioritize oxidative stability when selecting parent plants and preservation methods, particularly for long-term seed banking. Cultivators managing post-harvest quality monitor environmental factors (temperature, humidity, light, oxygen exposure) to minimize terpene loss, which directly impacts consistency across batches and storage longevity.
