If you take some time to analyze the trends of the current market, you can always find CBD in the list of trending products. It rose to the current position within a surprisingly short time span after its legalization in 2018. CBD is extracted from hemp plants, and on its transformation to various product forms, the cannabinoid undergoes several steps of extraction and purification.

In this session, we discuss some of the popular extraction methods of CBD.

CO2 Extraction

This extraction method has the reputation of offering highest levels of purity, which explains why most of the reputed CBD manufacturers use CO2 extraction to manufacture their products. The method requires expensive equipment that increases the overall cost of the extraction method but the method offers failsafe security and purity.

CO2 extraction uses supercritical CO2 that is in a state between liquid and gas. CO2 is converted to supercritical state by subjecting it to a high pressure, low temperature environment for a specific amount of time. The whole extraction process takes place in a closed loop extractor that has three chambers. The first chamber holds pressurized CO2, which is pumped into the second chamber that holds hemp plant material. As supercritical CO2 is run through the plant material, cannabinoids are extracted from it and pumped to the final chamber where CO2 is isolated from the extract.

Solvent Extraction

Solvent extraction involves the use of any solvents like ethanol, butane, propane etc to extract CBD from hemp plant and it is famous as a less expensive option. However, the flammable solvents used in the process makes it a dangerous extraction method.

As the initial step in the extraction process, plant trimmings are placed put into the container of the extraction chamber and the solvent is run through the plant material to extract cannabinoids from it. The solvents are removed from the final product through evaporation.

The toxicity of solvents like butane is a downside of solvent extraction process and even trace amounts of butane solvent that remains in the final product can affect the health of the user adversely. Among various solvent extraction methods, the method that uses ethanol is preferred the most because ethanol is grain alcohol that does not have a toxic nature.

Although several CBD extraction methods are available, experts strongly recommend ethanol extraction and CO 2 extraction due to their extraction efficacy and use of non-toxic extraction materials.
