Oxidation Processes

Oxidation processes in cannabis refer to chemical reactions where terpenes and other volatile compounds lose electrons when exposed to oxygen, light, or heat. These reactions occur throughout the plant's lifecycle—during growth, harvest, drying, curing, and storage—and significantly alter the terpene profile and aromatic character of cannabis material. Common oxidation pathways include terpene degradation into secondary compounds, polymerization into larger molecules, and conversion into novel volatile aldehydes and ketones. Understanding oxidation is critical for preservation, as it explains why fresh flower aromatics differ substantially from aged or improperly stored material. Breeders and cultivators monitor oxidation rates to optimize harvest timing and post-harvest handling protocols.

Breeders select for cultivars with oxidation-stable terpene profiles when targeting consistent end-product aromatics and stability across storage conditions. Lineage records frequently document how certain genetic backgrounds resist or accelerate oxidative degradation, informing breeding decisions for commercial cultivation and seed preservation programs.
