Limonene Oxidation

Limonene oxidation refers to the chemical degradation of limonene, a major terpene in cannabis, when exposed to heat, light, or oxygen over time. This process transforms the fresh, citrus-forward aroma profile into more muted or altered scent characteristics. Breeders and cultivators studying limonene stability track how storage conditions, harvest timing, and plant genetics affect terpene preservation. Understanding limonene oxidation is relevant for seed banks, breeding programs focused on terpene retention, and lineages selected for environmental resilience. Research into oxidation resistance informs decisions about drying, curing, and long-term seed viability protocols.

Breeders working in preservation and seed longevity often select for genetic traits that slow limonene degradation, as oxidation-resistant phenotypes better maintain volatile profiles across storage cycles. This trait category is particularly relevant for breeding programs developing cultivars intended for regulated markets with strict shelf-life standards.
