What is CO2 extraction?
The carbon dioxide (CO2) extraction process makes use of pressurised CO2 to draw out compounds like cannabidiol (CBD) and cannabigerol (CBG), from the cannabis plant. When CO2 reaches specific temperatures and pressures, it becomes the medium in which cannabinoids, terpenes and other compounds are captured. The CO2 is then removed, leaving behind the desired compounds. CO2 extraction has been used for many years in various other industries. For example, the method is involved in removing caffeine from coffee beans, and in making essential oils from plants such as lavender. CO2 extraction is regarded as one of the leading extraction methods in the cannabis industry, as it has many benefits compared to other extraction methods.
Why do we choose CO2 extraction?
Cedar Creek chooses CO2 extraction because it is seen as the safest and most effective extraction method. Other extraction methods use chemical solvents such as butane and propane to capture the CBD. These methods pose the risk of leaving traces of those chemical solvents in the final product, which can be hazardous to the health of those using the product.
This is especially relevant in cases of people with weak or compromised immune systems using CBD to improve their wellness. Cedar Creek products provide the best that nature has to offer, with no toxic contaminants or adulterants.
CO2 extraction is highly efficient compared to other methods because it allows for the extraction of more cannabinoids and other valuable compounds such as terpenes.This results in a better quality and ultimately a more effective product.
Another reason we prefer CO2 extraction is that it is more environmentally friendly. CO2 extraction does not result in the same environmental contamination as extraction methods involving solvents like butane, propane and ethanol.
What is subcritical CO2 extraction?
Cedar Creek products are made using subcritical CO2 extraction. This means that the CO2 is heated and pressurized less than that of other CO2 extraction methods. It is more sensitive in nature.
Certain compounds, such as terpenes and flavonoids, are volatile and evaporate easily during other extraction processes. The milder temperature and pressure of subcritical extraction ensures that these more volatile compounds are captured instead.
Research suggests that terpenes and flavonoids contribute to the efficacy and bioavailability of the final product. This is due to a phenomenon known as the “entourage effect”, in which cannabinoids, terpenes and other trace compounds work together to create a combined effect which is greater than the sum of the parts.
