Lipid Oxidation

Lipid oxidation refers to the chemical breakdown of fatty compounds in cannabis plant material, a process that occurs naturally over time and during drying, curing, and storage. This family of chemical reactions involves the degradation of lipids—including fats, waxes, and lipid-bound compounds—through exposure to oxygen, heat, light, and microbial activity. Breeders and cultivators monitor lipid oxidation because it directly affects terpene stability, cannabinoid preservation, and the shelf life of dried flower and concentrates. The rate and extent of lipid oxidation varies significantly based on genetics, harvest timing, drying methods, and storage conditions. Understanding lipid oxidation is essential for seed preservation, clone longevity, and producing stable phenotypes across growing cycles.

Breeders select for genetic factors that slow lipid oxidation to improve product stability and consistency across generations. Cultivators working with specific lineages often adjust curing protocols and storage conditions to minimize oxidative degradation of desirable volatile and semi-volatile compounds.
