Oxidative Terpene Chemistry

Oxidative terpene chemistry describes the chemical transformations that occur when terpenes react with oxygen, light, or heat during cultivation, drying, curing, and storage. These reactions can convert primary terpenes into secondary compounds, altering both the chemical profile and aromatic character of cannabis material over time. Understanding oxidation pathways is important for breeders and cultivators seeking to preserve or intentionally develop specific terpene profiles. Common oxidative byproducts include alcohols, ketones, and esters that may contribute to the complexity of cured cannabis aroma. Environmental factors—particularly temperature, humidity, and light exposure—significantly influence the rate and direction of oxidative terpene reactions.

Breeders working with specific terpene profiles must account for oxidative stability when selecting genetics, as some cultivars show greater terpene retention through cure cycles than others. Understanding oxidative chemistry helps explain why post-harvest handling and storage conditions critically impact the final expressed terpene profile of any given strain.
