Extraction methods

Extraction methods

The method of extraction can have a big impact on the final product, these terms provide insight as to what happens during the extraction process.

Closed-loop Extraction

Closed-loop extraction is a type of hydrocarbon extraction where the extraction process occurs entirely within a closed system. This keeps the solvent from making any contact with the outside atmosphere. Closed-loop systems offers benefits that other extraction methods are unable to provide, such as safety and efficiency. In a closed-loop extraction systems use solvents to extract cannabinoids, terpenes, and other materials from the hemp plant. The solvent moves from a containment tank into an area where it can wash over the plant material. The system recycles the solvent, so it washes over the cannabis many times repeatedly. The concentrate is then refined, purged of the solvent, and collected. We test all of our concentrates prior to formulating our oils to make sure that none of the solvent used during extraction remain in our concentrated oil.

Decarboxylation

Decarboxylation, which occurs through heating, is the process by which CBDA is converted into CBD. This happens because when the CBDA is heated it undergoes a chemical change which results in the loss of a carboxyl group. This is why the process is called decarboxylation. This is the same process that converts THCa to THC. In order to preserve terpenes and cannabinoids, this process must happen slowly and at a low temperature.
