Oxidation And Conversion

Oxidation and conversion refer to chemical transformations that occur in cannabis plant material over time, particularly after harvest and during curing, storage, or aging. These processes involve the breakdown and recombination of cannabinoids, terpenes, and other compounds through exposure to oxygen, light, heat, and microbial activity. Breeders and researchers track oxidation states to understand how fresh flower profiles evolve into aged or degraded material. The term is also applied in breeding contexts to describe genetic lines selected for stability or intended volatility of aromatic compounds. Oxidation can alter aroma descriptors significantly—for example, certain terpenes may oxidize into new chemical profiles over weeks or months. Understanding these processes is central to preservation strategies and storage protocol development.

Breeders working in this category often select for or against oxidation-prone genetics, depending on intended shelf life and desired long-term flavor stability. Seed lines bred for storage resilience or rapid aromatic development during cure require knowledge of oxidation chemistry.
