Enzymatic Activity Post Harvest

Enzymatic activity post-harvest refers to the ongoing biochemical processes occurring in dried and cured cannabis tissue after harvest. These enzymatic reactions—driven by endogenous plant enzymes—continue to break down chlorophyll, degrade lipids, and transform volatile compounds even after the plant material has been dried. The extent and nature of these reactions depend heavily on storage temperature, humidity, light exposure, and initial plant material moisture content. Lineage records and breeder notes frequently document how different cultivars exhibit varying rates of enzymatic degradation during the cure phase, affecting both aroma stability and terpene profile evolution. Understanding these post-harvest biochemical processes is central to optimizing preservation methods and predicting long-term sensory trait retention in stored genetics.

Breeders working in preservation and long-term seed banking study enzymatic activity patterns to predict how parent genetics will age and how terpene profiles will shift during storage. This knowledge informs selection for traits associated with enzymatic stability, helping establish which lineages maintain aroma consistency versus those prone to rapid oxidative or enzymatic degradation.
