Volatile Compound Isomerization

Volatile compound isomerization refers to the structural rearrangement of terpenes and other aromatic molecules during cannabis curing, storage, or heating. Isomers share identical molecular formulas but differ in atomic arrangement, altering aroma and chemical profile without changing the base compound count. In cannabis breeding contexts, isomerization is relevant to preservation strategies and post-harvest chemistry. Breeders and cultivators track how temperature, light, and humidity influence terpene stability and transformation over time. Understanding isomerization helps explain why fresh flower and cured flower may express notably different aromatic profiles despite identical starting chemotypes. This process is central to seed banking, storage protocol development, and reproducibility in breeding programs.

Breeders working with terpene-dominant phenotypes monitor isomerization rates during curing trials to predict shelf-life and stability of desired aromatic profiles. Controlling post-harvest conditions to minimize or direct isomerization is part of phenotype standardization and line maintenance.
