Oxidation Processes

Oxidation processes in cannabis refer to chemical reactions where plant compounds break down or transform when exposed to oxygen, light, or heat during curing, storage, and aging. These reactions significantly alter volatile terpene profiles and cannabinoid composition over time. Chlorophyll degradation, terpene oxidation, and cannabinoid decarboxylation are key mechanisms breeders and cultivators monitor. Understanding oxidation is critical for seed preservation, post-harvest handling, and predicting how a strain's aroma will evolve. Properly controlled oxidation during curing can develop complexity in aroma profiles, while uncontrolled oxidation typically results in loss of volatile compounds and aroma deterioration.

Breeders studying oxidation stability evaluate how specific genetic lines retain or lose aromatic compounds under various storage conditions. Selecting for stable terpene profiles and robust cannabinoid structures helps develop cultivars that maintain desirable aromatic characteristics during standard curing and storage periods.
