CO2 Extract Definition » Cannabis Dictionary

CO2 extraction is a type of supercritical fluid extraction used to maximize the cannabinoids and terpenes of the marijuana plant while still maintaining their delicate structure. A supercritical fluid behaves both like a gas and like a
liquid-diffusing through solids like a gas but dissolving compounds like a liquid. The supercritical CO2 goes through a series of extraction vessels at specific pressures and temperatures, flooding the ground plant material and extracting those clean cannabinoid profiles. It is then separated and filtered from the plant material and, after the extraction is complete, a drop in pressure allows the excess CO2 to evaporate, leaving the cannabis oil behind.

The benefit of CO2 extraction is that it is naturally occurring and leaves behind no residues. Other examples of CO2 extractions in the food industry include the extraction of flavor oils from hops in the brewing industry and extraction of caffeine from coffee beans. Fun Fact: Most concentrates are made using shake, trim and undesirable buds that aren’t fit to smoke.

What is CO2 extraction and how is it used in cannabis concentrate processing?

CO2 extraction is a method of extracting essential oils and other compounds from plant material using carbon dioxide as a solvent. In cannabis concentrate processing, CO2 extraction is used to extract cannabinoids and terpenes from the plant material, resulting in a highly concentrated oil that can be used for various purposes.

What are the benefits of using CO2 extraction for cannabis concentrates?

CO2 extraction is a safe and efficient method of extracting cannabinoids and terpenes from cannabis plant material. It produces a high-quality concentrate that is free of residual solvents and contaminants, and it allows for precise control over the extraction process, resulting in a consistent and reliable product.

How does CO2 extraction compare to other methods of cannabis concentrate processing?

Compared to other methods of cannabis concentrate processing, such as butane extraction or ethanol extraction, CO2 extraction is generally considered to be safer and more efficient. It produces a higher quality concentrate that is free of residual solvents and contaminants, and it allows for precise control over the extraction process.

What factors affect the quality of CO2-extracted cannabis concentrates?

The quality of CO2-extracted cannabis concentrates can be affected by a number of factors, including the quality of the starting material, the temperature and pressure used during the extraction process, and the post-processing techniques used to refine the concentrate. It is important to use high-quality starting material and to carefully control the extraction process in order to produce a high-quality concentrate.

What are some common uses for CO2-extracted cannabis concentrates?

CO2-extracted cannabis concentrates can be used for a variety of purposes, including vaporizing, dabbing, and adding to edibles or other products. They are highly concentrated and potent, so it is important to use them responsibly and in accordance with local laws and regulations.
