Cannabinoid Degradation

Cannabinoid degradation refers to the chemical breakdown of cannabinoids (THC, CBD, CBN, etc.) over time through oxidation, heat, light exposure, and enzymatic processes. This occurs naturally during plant senescence, post-harvest handling, storage, and processing. Understanding degradation pathways is critical for breeders and cultivators seeking to preserve cannabinoid profiles and prevent unwanted conversion—for example, THC oxidizing to CBN or CBD decarboxylating under heat. Lineage records and stability testing help identify cultivars with more robust cannabinoid retention under standard storage conditions. Research into this mechanism informs seed preservation protocols and breeding strategies aimed at chemical stability.

Breeders working in this category select for cultivars that maintain cannabinoid expression and resist degradation during cure, storage, and shelf life. Stability testing across temperature and humidity ranges helps identify genetic factors influencing cannabinoid longevity, informing long-term seed viability and product consistency.
