Oxidation Rate

Oxidation rate refers to the speed at which cannabis plant material undergoes chemical breakdown when exposed to oxygen, light, and time. This process affects terpene stability, cannabinoid degradation, and overall aromatic profile development during curing and storage. Breeders and cultivators monitor oxidation because faster rates can lead to browning, loss of volatile compounds, and shifts in perceived aroma. Genetics, environmental conditions during drying, and storage methods all influence how quickly oxidation occurs. Understanding oxidation is foundational to preservation practices and predicting how a strain's aroma will evolve post-harvest.

Breeders working in cultivar preservation often select for genetics that exhibit slower oxidation rates, as this trait supports longer shelf-life stability of terpene profiles and cannabinoid integrity. Oxidation rate is also monitored as an indirect marker of plant tissue density and wax layer composition, traits that correlate with certain genetic backgrounds.
