CO2 Extraction method
Valens Groworks, Neptune Solutions and MediPharm Labs use CO2 extraction method.
What is CO2 Extraction?
The Supercritical CO2 extraction process creates phase changes in carbon dioxide utilizing temperature and pressure. CO2 is known as a “tunable solvent” making it extremely versatile for creating a multitude of end products by controlling temperature and pressure. These phase changes create an environment to drop out differing weights of components in the plant material.
Why use CO2?
The primary reason is to create a pure, clean, quality oil that is safe to produce with little-to- no post-processing, unlike toxic solvents that may require many hours to purge the solvent trapped in the oil. In addition, multiple industries have proven that the highest efficiencies in commercial processing utilize CO2.
CO2 is efficient, inexpensive and is a “tunable” solvent. The ability to “tune” the extraction process can not be overstated – especially with a system that will separate constituents during an extraction. You can target specific compounds, like terpenes (terpenoids) through different parameters. CO2 is also a sanitizing agent, prolonging shelf life and with the proper system and environment, yields food and medical grade oils.
CO2 extraction is the cleanest, safest method for extracting plants such as hops, cannabis and a wide range of nutraceuticals and organic crops.
