Low Temperature Processing

Low temperature processing refers to extraction and handling methods conducted below standard ambient conditions, typically between -20°C and 0°C, designed to preserve volatile aromatic compounds and cannabinoids that degrade under heat. Cannabis processors employ techniques like cold ethanol extraction, dry ice handling, and frozen material preparation to minimize terpene loss during separation. Lineage records and terpene profiles often show measurably higher aromatic compound retention when plant material undergoes low-temperature workflows compared to heated methods. This approach is particularly relevant in breeding programs focused on preserving strain-specific terpene signatures and organoleptic markers. The technique emerged from cannabis research literature examining post-harvest optimization rather than cultivation itself.

Breeders and seed producers working to preserve and document accurate terpene expressions in their lines increasingly partner with processors using low-temperature methods to generate authentic cannabinoid and terpene data for phenotype selection and strain documentation.
