Flash Frozen Material

Flash freezing is a preservation technique where freshly harvested cannabis material is rapidly frozen at sub-zero temperatures, typically using liquid nitrogen or ultra-cold freezers. This method aims to preserve volatile terpene profiles and cannabinoid structure by halting enzymatic degradation and oxidation immediately after harvest. Flash-frozen material is commonly used in extraction workflows, rosin pressing, and live resin production, where breeders and processors seek to capture the most aromatic and chemically intact plant profile possible. The technique differs from standard drying and curing, which involve slower moisture removal and enzymatic conversion over weeks.

Breeders and seed producers working with flash-frozen samples can assess raw terpene expression without the chemical shifts that occur during traditional drying. This allows for more accurate phenotype characterization and terpene stability evaluation across generations, supporting selective breeding for terpene-rich genetics.
