Post Harvest Enzymatic Activity

Post-harvest enzymatic activity refers to the biochemical processes that continue in cannabis plant material after harvest, primarily involving oxidation, decarboxylation, and degradation of cannabinoids and terpenes. These enzymatic reactions are influenced by temperature, moisture, light exposure, and oxygen availability during drying, curing, and storage. Understanding enzymatic pathways helps explain how THCA converts to THC, how CBD stability changes, and how aromatic profiles shift over time. Breeders and cultivators study these processes to predict shelf stability and final cannabinoid profiles across different genetic backgrounds. Some strains show more robust enzymatic stability than others, making lineage selection relevant for producers managing long-term inventory.

Breeders tracking post-harvest enzymatic behavior often select for genetics that maintain cannabinoid and terpene stability across storage conditions. Genetics showing slower enzymatic degradation or controlled decarboxylation rates are valued in breeding programs focused on consistency and shelf life.
