Terpene Oxidation

Terpene oxidation refers to the chemical degradation of cannabis terpenes through exposure to oxygen, light, and heat over time. This process converts volatile aromatic compounds into secondary metabolites, altering the aroma profile and chemical composition of stored plant material or extracts. Understanding oxidation is central to preservation strategy, as it directly impacts the stability of terpene-rich phenotypes during curing, storage, and breeding work. Breeders and cultivators commonly track oxidation rates when evaluating cultivar stability and shelf-life potential. The process occurs naturally during post-harvest handling but can be accelerated by improper environmental conditions. Lineage records frequently note oxidation resistance as a desirable trait in modern preservation-focused breeding programs.

Breeders working in preservation genetics select for cultivars that resist rapid terpene oxidation, as this trait affects reproducibility across generations and market viability of cured material. Oxidation-resistant phenotypes allow more consistent aromatic expression across stored seed lots and harvests.
