Oxidation And Degradation

Oxidation and degradation refer to chemical processes that break down terpenes and cannabinoids over time when cannabis material is exposed to oxygen, light, heat, or microbial activity. These reactions alter the molecular structure of volatile compounds, changing aroma profiles, potency, and overall quality of stored flower or concentrate. Terpene oxidation commonly occurs during improper drying, curing, or storage—particularly when buds are exposed to air without humidity control. Degradation can shift fresh citrus or floral notes toward woody, musty, or off-flavor characteristics. Understanding these processes is central to preservation strategy and breeding work focused on stability and shelf-life performance.

Breeders and cultivators working to develop strains with extended storage potential often select for plants with natural antioxidant compounds or denser trichome coverage that slows terpene loss. Cultivators use controlled environment practices—precise humidity, light exclusion, and cool temperatures—to minimize oxidative damage and maintain genetic expression of intended terpene profiles.
